網(wǎng)上有很多方案，起初用時，因為對asp.net不太了解，覺得FTP實現(xiàn)不錯，可是后來發(fā)現(xiàn)，如果機器在域控下，就會有問題。
一年過去了，asp.net也熟悉了，知道ajax沒事應該用ashx，驗證碼也用ashx，當然這里要說的WinForm上傳也應該是ashx了吧，哈哈，先提供簡單思路：
接收文件的asp.net是：Uploader.ashx，相關(guān)代碼：
- <%@ WebHandler Language="C#" Class="Uploader" %>
- using System;
- using System.IO;
- using System.Web;
-
- public class Uploader : IHttpHandler
- {
- public void ProcessRequest(HttpContext hc)
- {
- foreach (string fileKey in hc.Request.Files)
- {
- HttpPostedFile file = hc.Request.Files[fileKey];
- file.SaveAs(Path.Combine(hc.Server.MapPath("."), file.FileName));
- }
- }
-
- public bool IsReusable
- {
- get { return true; }
- }
- }
<%@ WebHandler Language="C#" Class="Uploader" %>
using System;
using System.IO;
using System.Web;
public class Uploader : IHttpHandler
{
public void ProcessRequest(HttpContext hc)
{
foreach (string fileKey in hc.Request.Files)
{
HttpPostedFile file = hc.Request.Files[fileKey];
file.SaveAs(Path.Combine(hc.Server.MapPath("."), file.FileName));
}
}
public bool IsReusable
{
get { return true; }
}
}
發(fā)送圖片或文件的WinForm.cs 相關(guān)代碼：
- System.Net.WebClient myWebClient = new System.Net.WebClient();
- myWebClient.UploadFile("http://www.yongfa365.com/Uploader.ashx", "POST", "C:\\WINDOWS\\system32\\cmd.exe");
System.Net.WebClient myWebClient = new System.Net.WebClient();
myWebClient.UploadFile("http://www.yongfa365.com/Uploader.ashx", "POST", "C:\\WINDOWS\\system32\\cmd.exe");
OK,完了，這樣操作后，再也不用管是不是在域控內(nèi)了，只要能上網(wǎng)，就能上傳。夠方便吧。
如果你要批量上傳，還有上傳后保存在哪個目錄等操作可以參考寫的：
