.net 调用webservice 总结

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Services;namespace TestWebService{ /// <summary> /// Service1 的摘要说明 /// </summary> [WebService(Namespace = "http://tempuri.org/",Description="我的Web服务")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。 // [System.Web.Script.Services.ScriptService] public class TestWebService : System.Web.Services.WebService { [WebMethod] public string HelloWorld() { return "测试Hello World"; } [WebMethod] public string Test() { return "测试Test"; } [WebMethod(CacheDuration = 60,Description = "测试")] public List<String> GetPersons() { List<String> list = new List<string>(); list.Add("测试一"); list.Add("测试二"); list.Add("测试三"); return list; } }}
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
View Codeusing 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：

方法三：利用http 协议的get 和post
这是最为灵活的方法。
