End Class 2. asp.net調(diào)用，添加Web References。
Dim s As String
Dim t As New mingservice.Service1
ResultAdd.Text = t.add(CInt(Param1.Text), CInt(Param2.Text))
3. VB6調(diào)用，安裝SoapToolkit20.exe。添加References：C:\Program Files\Common Files\MSSoap\Binaries\MSSOAP1.dll.
Dim sc As New MSSOAPLib.SoapClient
sc.mssoapinit "http://192.168.0.8/VSService/Service1.asmx?WSDL"
Text3.Text = sc.Add(CInt(Text1.Text), CInt(Text2.Text))
4.ASP調(diào)用，安裝SoapToolkit20.exe。添加References：C:\Program Files\Common Files\MSSoap\Binaries\MSSOAP1.dll.

t1 = Request.Form("text1")
t2 = Request.Form("text2")
url = "http://192.168.0.8/VSService/Service1.asmx/add"

xmlhttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
xmlhttp.setRequestHeader "HOST","192.168.0.8"
xmlhttp.setRequestHeader "Content-Length",LEN(SoapRequest)
xmlhttp.Send(SoapRequest)
If xmlhttp.Status = 200 Then
Set xmlDOC = server.CreateObject("MSXML.DOMDocument")
xmlDOC.load(xmlhttp.responseXML)
t3=xmlDOC.childNodes(1).Text
Set xmlDOC = nothing
Else
Response.Write xmlhttp.Status&" "
Response.Write xmlhttp.StatusText
End if
Set xmlhttp = Nothing
