Asp.net 2.0 中将�|�站首页生成�?r��n)态页的一个比较好的方�?

圣域飞侠 — Wed, 11 Apr 2007 09:51:00 GMT

做网站时,有时��Z��(ji��n)提高性能�?x��)将�|�站首页生成�?r��n)态页(当然, Asp.net中页面缓存�(sh��)��是一个不错的选择�?
��页面生成静(r��n)态的�Ҏ(gu��)��有多�?据不完全�l�计有N�U?N>1)
呵呵
以下的方法来�?nbsp;"孟子E " 解释的方�?

代码如下

    protected override void Render(HtmlTextWriter writer)
    ...{
        System.IO.StringWriter html = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter tw = new HtmlTextWriter(html);
        base.Render(tw);
        System.IO.StreamWriter sw = new System.IO.StreamWriter(Server.MapPath("index.html"), false, System.Text.Encoding.Default);
        sw.Write(html.ToString());
        sw.Close();
        tw.Close();
        Response.Write("��面生成成功!");
    }
��以上上函数数加如到你要生成�?r��n)太文�g的页面里,
函数从蝲�?Render函数作用是把��面�?nbsp;html文本截下�?保存到文仉��,
�q�一步的可以�ȝ��一下asp.net��面生命�q�程.

�?r��n)态页面的生成

protected override void Render(HtmlTextWriter writer) {
     StreamWriter r=new StreamWriter(Server.MapPath(StaticFileName),
           false,System.Text.Encoding.UTF8);  //StaticFileName是html文�g�?
     HtmlTextWriter h=new HtmlTextWriter(r);
     base.Render(h);
     r.Close();
     h.Close();
     Response.Redirect(StaticFileName);
}

然后在同一aspx的pageLoad事�g中判断StaticFileName是否已经存在�Q�如果存在，��应该直接�{向，不应该��l�生成页面了(ji��n)�?img src ="http://www.tkk7.com/yeiwei/aggbug/109966.html" width = "1" height = "1" />

ASP.NET生成�?r��n)态页面实现方�?

圣域飞侠 — Wed, 11 Apr 2007 09:50:00 GMT

<%@ page language="C#" %>
<%@ import namespace=System.IO %>

<%@ page language="C#" %>

　 Untitled Page

ID:
<%=Request.QueryString["id"]%>

其中原理是这��L(f��ng)��.
Main_Execute.aspx是生成HTML的页�?

现在用Main.aspx来对它进行缓�?
�q�程如下:

首先�Ҏ(gu��)��面参数��出文�g�?(�q�个例子只根据Request.QueryString["id"]来算)
��试��d��~�存的文�?如果成功,那么Response.End();
如果不成�?
使用Server.Execute来调用Main_Execute.aspx,�q�且获取它的�l�果内容.
得到内容�?立刻输出到客��L(f��ng)��.
最后把内容写进文�g�?提供�l�下一�ơ做为缓存度�?

Orcas中C#语言的新�Ҏ(gu��)��：(x��)自动属性，对象初始化器�Q�和集合初始化器

圣域飞侠 — Wed, 11 Apr 2007 09:47:00 GMT

几个星期前，我曾在博客上讨论�q�Orcas中针对ASP.NET开发�h员的一些重大的改进。如果你�q�没有读�q�这个脓(chu��ng)子的话，我强烈徏议你在这里读一�?/font>。我认�ؓ(f��)你会(x��)非常喜欢该帖子讨论的新特性的�?

除了(ji��n)那些框架和工��L(f��ng)��的精彩新�Ҏ(gu��)��外�Q�我认�ؓ(f��)开发�h�?包括所有的.NET应用�c�d��的开发�h�?�?x��)非常喜爱O(ji��n)rcas的一件事情是�Q�VB和C#��包含一些新语言�Ҏ(gu��)��和改进。这些语�a�改动��以既微妙又深刻的方式改�q�我们的开发体验，势将改进效率�Q�减��我们需要键入的代码量�?

在下几个星期里，我将试着在博客里讨论几个�q�些语言的改�q�之处，�C��如何把它们��用在一��P��来��生一些非常强有力的结果�?/p>

新的C#语言�Ҏ(gu��)��：(x��)自动属�?Automatic Properties)

如果你现在是C#开发�h员的话，你大概非�怹�(f��n)惯编写象下面�q�个代码片段一样带有基本属性的�c�d��Q?/p>

    public class Person {

        private string _firstName;
        private string _lastName;
        private int _age;
        
        public string FirstName {

            get {
                return _firstName;
            }
            set {
                _firstName = value;
            }
        }

        public string LastName {

            get {
                return _lastName;
            }
            set {
                _lastName = value;
            }
        }        
        
        public int Age {

            get {
                return _age;
            }
            set {
                _age = value;
            }
        }
    } 

注意�Q�我们在属性的geter/setter中实际上�q�没有添加什么逻辑�Q�我们只是将get/set实施��C��(ji��n)一个成员变量。我们不��要问这样一个问题：(x��)��Z��么不直接使用成员变量而��用属性呢�Q�这是因为，向外面呈现公开的成员变量有很多不好的地斏V��二个最大的问题是：(x��)1) 你无法轻易地�Ҏ(gu��)��员变量做数据�l�定�Q?) 如果你从�c�M��向外呈现成员变量的话�Q�之后，你不重新�~�译那些引用老的�cȝ��M��E�序集，��无法将它们�Ҏ(gu��)��属�?譬如�Q�要��d��验证逻辑到setter�?�?

Orcas中发布的新C#�~�译器通过一个叫“自动属�?automatic properties)”的语�a��Ҏ(gu��)��提供了(ji��n)一个优雅的方式来��得你的编码更加简�z�，同时�q��(sh��)��持属性的灉|��性。自动属性允�怽�避免手工声明一个私有成员变量以�?qi��ng)编写get/set逻辑�Q�取而代之的是，�~�译器会(x��)自动��Z��生成一个私有变量和默认的get/set 操作�?/p>

譬如�Q��用自动属性，我现在可以将上面的代码改写成�Q?/p>

    public class Person {
    
        public string FirstName {
            get; set;
        }

        public string LastName {
            get; set;
        }        
        
        public int Age {
            get; set;
        }
    } 

或者，我想更简明的话，我可以将�I�白的地方做�q�一步压�~�，象这��P��(x��)

    public class Person {
        public string FirstName { get; set; }
        public string LastName  { get; set; }        
        public int    Age       { get; set; }
    } 

当Orcas版中的C#�~�译器遇上象上面�q�样的空的get/set属性的话，它会(x��)自动��Z��在类中生成一个私有成员变量，对这个变量实��C��个公开的getter 和setter。这么做的好处是�Q�从�c?合同(type-contract)的角度来看，�q�个�c�跟我们上面�W�一个有点冗长的实现看上��d��全一��P��q�意味着�Q�不象公开的成员变量，在将来，我可以在我的属性setter实现中添加验证逻辑�Q�而不用对引用我的�cȝ��M��外部�l��g做改动�?/p>

Bart De Smet对��用Orcas三月份CTP版中的自动属性时内部发生的情形作�?ji��n)精彩的描述�Q�你可以在这里阅��M��的精彩相兛_��?/font>�?

C#和VB语言的新�Ҏ(gu��)��：(x��)对象初始化器(Object Initializers)

.NET框架中的�c�d��非常依赖于属性的使用。当生成对象实例和��用新的类型时�Q�写�?gu��)��下面�q�样的编码是非常常见的情形：(x��)

   Person person = new Person();
   person.FirstName = "Scott";
   person.LastName = "Guthrie";
   person.Age = 32; 

你有没有惌��把这��L(f��ng)��~�码��化过(也许��其安排在一行上)�Q��用Orcas中的C#和VB语言�~�译器的话，你现在可以利用一个称�?#8220;对象初始化器(object Initializers)”�?#8220;语法甜头(syntactic sugar)”语言�Ҏ(gu��)��来做些��化，��上�q�C��码重写�ؓ(f��)�Q?/p>

  Person person = new Person { FirstName="Scott", LastName="Guthrie", Age=32 }; 

然后�Q�编译器��׃��(x��)自动地生成合适的属性setter代码�Q�保持跟前面较冗长的代码例子同样的语意�?/p>

除了(ji��n)在初始化�c�L��讄��单的属性值外�Q�对象初始化器特性也允许我们讄��更复杂的嵌套(nested)属性类型。譬如，假如我们在上面定义的每个Person�c�d��也拥有一个属于Address�c�d��的叫“Address”的属性。我们可以编写下面这��L(f��ng)��代码来生成一个新的Person对象�Q�同时设�|�它的属性，象这��P��(x��)

   Person person = new Person {
      FirstName = "Scott",
      LastName = "Guthrie"
      Age = 32,
      Address = new Address {
         Street = "One Microsoft Way",
         City = "Redmond",
         State = "WA",
         Zip = 98052
      }
   }; 

Bart De Smet对��用Orcas三月份CTP版中的对象初始化器时内部发生的情形也作了(ji��n)�_�ֽ�的描�q�ͼ�你可�?a target=_blank>在这里阅��M��的精彩相兛_��?/font>�?

C#和VB语言的新�Ҏ(gu��)��：(x��)集合初始化器(Collection Initializers)

对象初始化器很棒�Q�它极大地简化了(ji��n)把对象添加到集合的做法。譬如，假如我要把三个�h加到一个基于泛型的�c�d��为Person的List集合中去的话�Q�我可以写下面这��L(f��ng)��~�码�Q?/p>

  List people = new List();
            
  people.Add( new Person { FirstName = "Scott", LastName = "Guthrie", Age = 32 } );
  people.Add( new Person { FirstName = "Bill", LastName = "Gates", Age = 50 } );
  people.Add( new Person { FirstName = "Susanne", LastName = "Guthrie", Age = 32 } );
  

对这个例子，跟我使用C# 2.0�~�译器要输入的代码相比，单独使用新的对象初始化器�Ҏ(gu��)��就能省�?2行额外的代码�?/p>

但Orcas版中的C#和VB�~�译器允许我们更�q�一步，现在同时支持“集合初始化器(collection initializers)”�Q�这允许我们避免要写多个Add语句�Q�省下更多的键盘操作�Q?/p>

   List people = new List {
      new Person { FirstName = "Scott", LastName = "Guthrie", Age = 32 },
      new Person { FirstName = "Bill", LastName = "Gates", Age = 50 },
      new Person { FirstName = "Susanne", LastName = "Guthrie", Age = 32 }
   }; 

当编译器遇上上面�q�样的句法时�Q�它�?x��)自动��?f��)我们生成象前面的例子一��L(f��ng)��集合插入�~�码�?/p>

�l�语

作�ؓ(f��)开发�h员，我们现在拥有�?ji��n)简明得多的方式来定义对象，对它们初始化�Q�将它们加入集合内。在�q�行�Ӟ��其语意，跟今天的较长的版本的语意�Q�是完全一��L(f��ng)��Q�所以你不必担心(j��)行�ؓ(f��)�?x��)改变�?j��)。但现在你不需输入那么多字�W�了(ji��n)�Q�你的代码将既干净又简明�?

在不�q�的��来�Q�我��发表更多的博客贴子来讨论Orcas版中更多的语�a�上的改进�Q�包括扩展方法（Extension Methods�Q�，Lambdas和匿名类。然后，我将对LINQ做深入讨论，�C��它是如何利用所有这些特性来提供一个非�怼�雅的方式来查询和与数据交互的�?/p>

C#和ASP.Net面试题目集锦

圣域飞侠 — Fri, 30 Mar 2007 03:35:00 GMT

1.有哪几种�Ҏ(gu��)��可以实现一个类存取另外一个类的成员函数及(qi��ng)属�?�q�请丑ֈ�来加以说明和分析.
2.A�c�L��B�cȝ��基类,�q�且都有自己的构�?析构函数,请�D例证明B�c�M��实例化到消亡�q�程中构�?析构函数的执行过�E?请附code
3.什么叫应用�E�序域？什么是受管制的代码�Q�什么是强类型系�l�？
4..Net中读写数据库需要用到哪些类�Q�他们的作用
5.ASP.net的��n份验证方式有哪些�Q�分别是什么原理？
6.解释一下UDDI、WSDL的意义及(qi��ng)其作用�?br>7.常用的调用webservice�Ҏ(gu��)��有哪些？
8.讲一讲你理解的web service,在dot net framework中，怎么很好的结合xml?�Q�讲概念��p��?ji��n)�?j��)
9.C#可否对内存进行直接的操作�Q?�q�可是个隄��哦？要注意！�Q?如果�?如何操作;如果不能,��Z��?
10.描述一下C#中烦(ch��)引器的实现过�E�，是否只能�Ҏ(gu��)��数字�q�行索引�Q?

1.面向对象的思想主要包括什么？
面向对象三大特征:�l�承,��套,多�?面相对象的思想也不是一句两句就能说清楚..主要思想��是减少代码重复,增大代码复用�?.

2.什么是ASP.net中的用户控�g
问这��L(f��ng)��问题,一般是�q�h��?因�ؓ(f��)新手�q�是分不清楚用户控�g和服务器控�g(也称自定义控�?..用户控�g一般用在内容多为静(r��n)�?或者少�怼�(x��)改变的情况下..用的比较�?.�c�M��ASP中的include..但是功能要强大的�?.

如果现有�?ASP.NET 服务器控仉��不符合应用程序的特定要求�Q�则可以创徏��装所需功能�?Web 用户控�g�?Web 自定义控件。这两种控�g之间的主要区别在于设计时的易创徏性与易用性�?/p>

Web 用户控�g易于创徏�Q�但它们在高�U�方案中使用��h��可能不太方便。开�?Web 用户控�g的方式与开�?Web �H�体��늚�方式几乎完全相同。与 Web �H�体�怼��Q�用��h��件可以在可视化设计器中创建，可以使用�?HTML 隔离的代码来�~�写�Q��ƈ且可以处理执行事件。但是，�׃�� Web 用户控�g在运行时动态地�q�行�~�译�Q�所以不能将它们��d��到工��L(f��ng)��中，而且它们在添加到��面上时��q��单的占位�W�标志符��h��表示。如果�?zh��n)�习(f��n)惯于完全�?Visual Studio .NET 设计时支持（包括“属�?#8221;�H�口�?#8220;设计”视图预览�Q�，�q�将�?x��)�?Web 用户控�g使用��h��更不方便�?此外�Q�在应用�E�序之间�׃�n用户控�g的唯一方式是将一个单独的副本攑օ�每个应用�E�序�Q�因此如果对该控件作��Z��(ji��n)更改�Q�将需要进行比较多的维护�?/p>

Web 自定义控件是�~�译的代码，�q��?Web 自定义控件更易于使用但更难于创徏�Q�Web 自定义控件必��M��用代码来创徏。一旦创��控�g�Q�那么，�(zh��n)�就可以��其��d��到工��L(f��ng)��中，�q�在��h��完全“属�?#8221;�H�口支持�?ASP.NET 服务器控件的其他所有设计时功能的可视化设计器中昄��该控件。此外，�q�可以在全局�E�序集缓存�(sh��)��安装 Web 自定义控件的单个副本�Q��ƈ在应用程序之间共享该副本�Q�这��ɾl�护变得更容易。有��x(ch��ng)��多信息，请参阅全局�E�序集缓存�?br>如果�(zh��n)�的控�g包含大量�?r��n)态布局�Q�用��h��件则可能是较佳的选择。如果�?zh��n)�的控件主要是动态生成的�Q�例如数据绑定表的行、树(w��i)视图的节�Ҏ(gu��)��选项�?(TabControl) 控�g的选项卡）(j��)�Q�自定义控�g则可能是较佳的选择�?/p>

下表概述�?ji��n)这两种�c�d��之间的主要区别：(x��)
Web 用户控�g
1.难于创徏
2.��Z��用可视化设计工具的��用者提供有限的支持
3. 每个应用�E�序中需要控件的一个单独副�?br>4. 不能��d��?Visual Studio 中的工具��?br>5. 适用于静(r��n)态布局
Web 自定义控�?br>1.易于创徏
2. ��Z��用者提供完全的可视化设计工��h��?br>3. 仅在全局�E�序集缓存�(sh��)��需要控件的单个副本
4. 可以��d��?Visual Studio 中的工具��?br>5. 适用于动态布局

3.什么叫应用�E�序域？什么是受管制的代码�Q�什么是强类型系�l�？什么是装箱和拆��？什么是重蝲�Q�CTS、CLS和CLR分别作何解释�Q?br>�q�个需要当前描�q�C��(ji��n)..东西太多..打字要打��M��(ji��n)..找个比较��单的说说�?
CTS:公共�c�d��pȝ��.主要是�ؓ(f��)�?ji��n)语�a�之间的进行标准化处理.
CLS:公共语言规范.主要是确保代码可以在��M��语言中访问的最��标准集�?br>CLR:公共语言�q�行�?主要是管理代�?.处理,加蝲代码,以及(qi��ng)所有服务的代码

4.列�D一下你所�?ji��n)解的XML技术及(qi��ng)其应�?br>xml用于配置,用于保存�?r��n)态数据类�?接触XML最多的是web Services..和config

5.值类型和引用�c�d��的区别？写出C#的样例代码�?br>值类型是在内存�(sh��)��保存,引用�c�d��是在内存?sh��)��保存?sh��)��副本.你在内存?sh��)��可以有多个某种引用对�?.但是值类型始�l�只有一�?
最常见的值类型就是static,struct;
例如:
static int aa = 1;//值类�?br>如果多个用户改变aa的值则,aa的��g��(x��)以最后一个修改的记录为准.其他人的修改则会(x��)被冲�?
引用�c�d��,最能说明问题的��是实例�?.你new出来的对象单独分配一个独立的内存..所以��g��?x��)互相冲�H?

数据成员可以分静(r��n)态变量、非�?r��n)态变量两�U?
�?r��n)态成员：(x��)�?r��n)态类中的成员加入static修饰�W?��x(ch��ng)��?r��n)态成�?可以直接使用�c�d��+�?r��n)态成员名讉K��此静(r��n)态成�?因�ؓ(f��)�?r��n)态成员存在于内存,非静(r��n)态成员需要实例化才会(x��)分配内存,所以静(r��n)态成员�(sh��)��能访问非�?r��n)态的成员..因�ؓ(f��)�?r��n)态成员存在于内存,所以非�?r��n)态成员可以直接访问类中静(r��n)态的成员.

非成�?r��n)态员�Q�所有没有加Static的成员都是非�?r��n)态成�?当类被实例化之后,可以通过实例化的�c�d��q�行讉K��..非静(r��n)态成员的生存期决定于该类的生存期..而静(r��n)态成员则不存在生存期的概�?因�ؓ(f��)�?r��n)态成员始�l�驻留在内容�?.

一个类中也可以包含�?r��n)态成员和非静(r��n)态成�?�c�M��也包括静(r��n)态构造函数和非静(r��n)态构造函�?.

对于winApp来说,�?r��n)态成员对于程序员本��n省了(ji��n)很多�?而且因�ؓ(f��)�?r��n)态成员驻留内�?在方法与�Ҏ(gu��)��之间传递共享数据的时�?所以静(r��n)态成员成�?ji��n)我的首�?.但是不要因�ؓ(f��)方便,大量使用,��其是在内存紧张或�?br> 用静(r��n)态方法操作一些共享值的时�?或者要写多用户�pȝ��的时�?要慎之又�?比如:
static int id = 0;
sql = "select * from table where id=" + id;l

6.ADO.net中常用的对象有哪些？分别描述一下�?br>Connection 数据库连接对�?br>Command 数据库命�?br>DataReader 数据��d��?br>DataSet 数据�?/p>

7.如何理解委托�Q?br>委托的概�?最好的说明��是事�g.因�ؓ(f��)事�g使用的就是委�?例如:this.Load += new System.EventHandler(this.Page_Load);�q�个��是使用�?ji��n)一个委�?
具体的用法请参�?我以前的帖子,设计猫鼠联动..

8.C#中的接口和类有什么异同�?br>�c�L��Ҏ(gu��)��功能的实现和集合,接口是规范类.�U�束�c?
