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;@H_502_9@ using System.IO;@H_502_9@ using System.Collections.Generic;@H_502_9@ using System.Linq;@H_502_9@ using System.Collections;@H_502_9@ using System.Web;@H_502_9@ using System.Net;@H_502_9@ using System.Reflection;@H_502_9@ using System.CodeDom;@H_502_9@ using System.CodeDom.Compiler;@H_502_9@ using System.Web.Services;@H_502_9@ using System.Text;@H_502_9@ using System.Web.Services.Description;@H_502_9@ using System.Web.Services.Protocols;@H_502_9@ using System.Xml.Serialization;@H_502_9@ using System.Windows.Forms;

namespace ConsoleApplication1@H_502_9@ {@H_502_9@     class Program@H_502_9@     {@H_502_9@         static void Main(string[] args)@H_502_9@         {@H_502_9@             WebClient client = new WebClient();@H_502_9@             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@H_502_9@             Stream stream = client.OpenRead(url);@H_502_9@             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。@H_502_9@             importer.Style = ServiceDescriptionImportStyle.Client; //生成客户端代理。@H_502_9@             importer.CodeGenerationoptions = CodeGenerationoptions.GenerateProperties | CodeGenerationoptions.GenerateNewAsync;

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

            CodeNamespace nmspace = new CodeNamespace(); //命名空间@H_502_9@             nmspace.Name = "TestWebService";@H_502_9@             CodeCompileUnit unit = new CodeCompileUnit();@H_502_9@             unit.Namespaces.Add(nmspace);

            ServiceDescriptionImportWarnings warning = importer.Import(nmspace,unit);@H_502_9@             CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp");

            CompilerParameters parameter = new CompilerParameters();@H_502_9@             parameter.GenerateExecutable = false;@H_502_9@             parameter.OutputAssembly = "MyTest.dll";//输出程序集的名称@H_502_9@             parameter.ReferencedAssemblies.Add("System.dll");@H_502_9@             parameter.ReferencedAssemblies.Add("System.XML.dll");@H_502_9@             parameter.ReferencedAssemblies.Add("System.Web.Services.dll");@H_502_9@             parameter.ReferencedAssemblies.Add("System.Data.dll");

            CompilerResults result = provider.CompileAssemblyFromDom(parameter,unit);@H_502_9@             if (result.Errors.HasErrors)@H_502_9@             {@H_502_9@                 // 显示编译错误信息@H_502_9@             }

            Assembly asm = Assembly.LoadFrom("MyTest.dll");//加载前面生成的程序集@H_502_9@             Type t = asm.GetType("TestWebService.TestWebService");

            object o = Activator.CreateInstance(t);@H_502_9@             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);@H_502_9@             //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@H_502_9@             foreach (string str in item)@H_502_9@                 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@H_502_9@             TextWriter writer = File.CreateText("MyTest.cs"); @H_502_9@             provider.GenerateCodeFromCompileUnit(unit,writer,null);@H_502_9@             writer.Flush();@H_502_9@             writer.Close();@H_502_9@         } @H_502_9@     }@H_502_9@ }

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：
