C# 调用webservice 几种办法（转载）

//=================================================================================================

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。
