.net 调用webservice 总结
最近做一个项目，由于是在别人框架里开发app,导致了很多限制，其中一个就是不能直接引用webservice 。
我们都知道，调用webserivice 最简单的方法就是在 "引用" 那里点击右键，然后选择"引用web服务"，再输入服务地址。
确定后，会生成一个app.config 里面就会自动生成了一些配置信息。
现在正在做的这个项目就不能这么干。后来经过一番搜索，就找出另外几种动态调用webservice 的方法。
废话少说，下面是webservice 代码
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
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();
}
}
}
在网上找了一个更为详细的

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。
