1.在webconfig写:
<add key="webservices" value="http://127.0.0.1/SendMessageServices/Send_Gsm_New.asmx"/>
2.新建类:WS_Read
using System;
using System.Collections;
using System.Text;
using System.Web.Services.Description;
using System.Configuration;
namespace Message
{
/// <summary>
/// WS_Read 的摘要说明。
/// </summary>
public class WS_Read
{
/// <param name="sUrl">WebService的http形式的地址</param>
/// <param name="NameSpace">欲调用的WebService的命名空间</param>
/// <param name="ClsName">欲调用的WebService的类名（不包括命名空间前缀）</param>
/// <param name="MethodName">欲调用的WebService的方法名</param>
/// <param name="args">参数列表</param>
/// <param name="sErrMsg">用于接收错误信息</param>
/// <returns>WebService的执行结果</returns>
/// <remarks>
/// 如果调用失败，将会通过参数ErrMsg返回错误信息
/// 异常信息可能会发生在两个地方：
/// 1、动态构造WebService的时候，CompileAssembly失败。
/// 2、WebService本身执行失败。
/// </remarks>
public static object InvokeWebservice(string sUrl,string @NameSpace,string ClsName,string MethodName,object[] args,out string sErrMsg)
{
sErrMsg = "";
if (sUrl == "")
{
sErrMsg = "";
return null;
}

try
{
//获取描述文档

System.CodeDom.CodeCompileUnit my_CodeCompileUnit = new System.CodeDom.CodeCompileUnit();
my_CodeCompileUnit.Namespaces.Add(my_CodeNamespace);
//step.3获取名称空间中导入内容的集合
my_SerDesrImport.Import(my_CodeNamespace, my_CodeCompileUnit);
//step.4访问代码编译器,构建动态编译器实例
Microsoft.CSharp.CSharpCodeProvider my_csc = new Microsoft.CSharp.CSharpCodeProvider();

//step.6执行动态编译

return null;
}
//编译结束，并且编译成功
//=====================================================//
//开始获取程序集
//*******************************************************
//step.1获取已编译侧程序集

}
catch (Exception ex)
{

}
}
public static string Get_WS(string parm)
{

}
}
3.调用类的方法:
public int ChargeUp(string acco, string pass)
{
int result;
string str_ws=WS_Read.Get_WS("webservices2");
string ErrMsg=String.Empty;
object[] args = new object[2];
args[0] =acco;
args[1] =pass;
result = (int)WS_Read.InvokeWebservice(str_ws, "SendMessageService", "Send_Gsm_New", "ChargeUp", args, out ErrMsg);
return result;
}
