动态调用示例：

方法一：

看到很多动态调用WebService都只是动态调用地址而已，下面发一个不光是根据地址调用，方法名也可以自己指定的,主要原理是根据指定的WebService地址的WSDL,然后解析模拟生成一个代理类,通过反射调用里面的方法

using System;
using System.IO;
using System.Collections.Generic;
using System.Linq;
using System.Collections;
using System.Web;
using System.Net;
using System.Reflection;
using System.CodeDom;
using System.CodeDom.Compiler;
using System.Web.Services;
using System.Text;
using System.Web.Services.Description;
using System.Web.Services.Protocols;
using System.Xml.Serialization;
using System.Windows.Forms;

namespace ConsoleApplication1
{
??? class Program
??? {
??????? static void Main(string[] args)
??????? {
??????????? WebClient client = new WebClient();
??????????? String url = "http://localhost:3182/Service1.asmx?WSDL";//这个地址可以写在Config文件里面，这里取出来就行了.在原地址后面加上： ?WSDL
??????????? Stream stream = client.OpenRead(url);
??????????? ServiceDescription description = ServiceDescription.Read(stream);

??????????? ServiceDescriptionImporter importer = new ServiceDescriptionImporter();//创建客户端代理代理类。

??????????? importer.ProtocolName = "Soap"; //指定访问协议。
??????????? importer.Style = ServiceDescriptionImportStyle.Client; //生成客户端代理。
??????????? importer.CodeGenerationOptions = CodeGenerationOptions.GenerateProperties | CodeGenerationOptions.GenerateNewAsync;

??????????? importer.AddServiceDescription(description,null,null); //添加WSDL文档。

??????????? CodeNamespace nmspace = new CodeNamespace(); //命名空间
??????????? nmspace.Name = "TestWebService";
??????????? CodeCompileUnit unit = new CodeCompileUnit();
??????????? unit.Namespaces.Add(nmspace);

??????????? ServiceDescriptionImportWarnings warning = importer.Import(nmspace,unit);
??????????? CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp");

??????????? CompilerParameters parameter = new CompilerParameters();
??????????? parameter.GenerateExecutable = false;
??????????? parameter.OutputAssembly = "MyTest.dll";//输出程序集的名称
??????????? parameter.ReferencedAssemblies.Add("System.dll");
??????????? parameter.ReferencedAssemblies.Add("System.XML.dll");
??????????? parameter.ReferencedAssemblies.Add("System.Web.Services.dll");
??????????? parameter.ReferencedAssemblies.Add("System.Data.dll");

??????????? CompilerResults result = provider.CompileAssemblyFromDom(parameter,unit);
??????????? if (result.Errors.HasErrors)
??????????? {
??????????????? // 显示编译错误信息
??????????? }

??????????? Assembly asm = Assembly.LoadFrom("MyTest.dll");//加载前面生成的程序集
??????????? Type t = asm.GetType("TestWebService.TestWebService");

??????????? object o = Activator.CreateInstance(t);
??????????? MethodInfo method = t.GetMethod("GetPersons");//GetPersons是服务端的方法名称,你想调用服务端的什么方法都可以在这里改,最好封装一下

??????????? String[] item = (String[])method.Invoke(o,null);
??????????? //注：method.Invoke(o,null)返回的是一个Object,如果你服务端返回的是DataSet,这里也是用(DataSet)method.Invoke(o,null)转一下就行了,method.Invoke(0,null)这里的null可以传调用方法需要的参数,string[]形式的
??????????? foreach (string str in item)
??????????????? Console.WriteLine(str);

??????????? //上面是根据WebService地址，模似生成一个代理类,如果你想看看生成的代码文件是什么样子，可以用以下代码保存下来，默认是保存在bin目录下面
??????????? TextWriter writer = File.CreateText("MyTest.cs");
??????????? provider.GenerateCodeFromCompileUnit(unit,writer,null);
??????????? writer.Flush();
??????????? writer.Close();
??????? }
??? }
}

方法二：利用 wsdl.exe生成webservice代理类:

根据提供的wsdl生成webservice代理类，然后在代码里引用这个类文件。

步骤：1、在开始菜单找到? Microsoft Visual Studio 2010 下面的Visual Studio Tools ， 点击Visual Studio 命令提示(2010)，打开命令行。

????????? 2、 在命令行中输入：? wsdl /language:c# /n:TestDemo /out:d:/Temp/TestService.cs http://jm1.services.gmcc.net/ad/Services/AD.asmx?wsdl

??????????????? 这句命令行的意思是：对最后面的服务地址进行编译，在D盘temp 目录下生成testservice文件。

????????? 3、 把上面命令编译后的cs文件，复制到我们项目中，在项目代码中可以直接new 一个出来后，可以进行调用。

?? 贴出由命令行编译出来的代码：

//------------------------------------------------------------------------------
// <auto-generated>
//???? 此代码由工具生成。
//???? 运行时版本:4.0.30319.225
//
//???? 对此文件的更改可能会导致不正确的行为，并且如果
//???? 重新生成代码，这些更改将会丢失。
// </auto-generated>
//------------------------------------------------------------------------------

//
// 此源代码由 wsdl 自动生成,Version=4.0.30319.1。
