End Class 2. asp.net调用，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调用，安装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调用，安装SoapToolkit20.exe。添加References：C:\Program Files\Common Files\MSSoap\Binaries\MSSOAP1.dll.

Set xmlDOC = server.CreateObject("MSXML.DOMDocument")
xmlDOC.load(xmlhttp.responseXML)
t3=xmlDOC.childNodes(1).Text
Set xmlDOC = nothing
Else
Response.Write xmlhttp.Status&" "
