這篇文章將為大家詳細(xì)講解有關(guān)怎么在.net中webservice進(jìn)行調(diào)用，文章內(nèi)容質(zhì)量較高，因此小編分享給大家做個(gè)參考，希望大家閱讀完這篇文章后對(duì)相關(guān)知識(shí)有一定的了解。
代碼如下:
View Code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
namespace TestWebService
{
/// <summary>
/// Service1 的摘要說(shuō)明
/// </summary>
[WebService(Namespace = "http://tempuri.org/",Description="我的Web服務(wù)")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// 若要允許使用 ASP.NET AJAX 從腳本中調(diào)用此 Web 服務(wù)，請(qǐng)取消對(duì)下行的注釋。
// [System.Web.Script.Services.ScriptService]
public class TestWebService : System.Web.Services.WebService
{
[WebMethod]
public string HelloWorld()
{
return "測(cè)試Hello World";
}
[WebMethod]
public string Test()
{
return "測(cè)試Test";
}
[WebMethod(CacheDuration = 60,Description = "測(cè)試")]
public List<String> GetPersons()
{
List<String> list = new List<string>();
list.Add("測(cè)試一");
list.Add("測(cè)試二");
list.Add("測(cè)試三");
return list;
}
}
}
動(dòng)態(tài)調(diào)用示例：
方法一：
看到很多動(dòng)態(tài)調(diào)用WebService都只是動(dòng)態(tài)調(diào)用地址而已，下面發(fā)一個(gè)不光是根據(jù)地址調(diào)用，方法名也可以自己指定的,主要原理是根據(jù)指定的WebService地址的WSDL,然后解析模擬生成一個(gè)代理類(lèi),通過(guò)反射調(diào)用里面的方法
復(fù)制代碼 代碼如下:

{
WebClient client = new WebClient();
String url = "http://localhost:3182/Service1.asmx?WSDL";//這個(gè)地址可以寫(xiě)在Config文件里面，這里取出來(lái)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();//創(chuàng)建客戶(hù)端代理代理類(lèi)。
importer.ProtocolName = "Soap"; //指定訪(fǎng)問(wèn)協(xié)議。
importer.Style = ServiceDescriptionImportStyle.Client; //生成客戶(hù)端代理。
importer.CodeGenerationOptions = CodeGenerationOptions.GenerateProperties | CodeGenerationOptions.GenerateNewAsync;
importer.AddServiceDescription(description, null, null); //添加WSDL文檔。
CodeNamespace nmspace = new CodeNamespace(); //命名空間
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";//輸出程序集的名稱(chēng)
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)
{
// 顯示編譯錯(cuò)誤信息
}
Assembly asm = Assembly.LoadFrom("MyTest.dll");//加載前面生成的程序集
Type t = asm.GetType("TestWebService.TestWebService");
object o = Activator.CreateInstance(t);
MethodInfo method = t.GetMethod("GetPersons");//GetPersons是服務(wù)端的方法名稱(chēng),你想調(diào)用服務(wù)端的什么方法都可以在這里改,最好封裝一下
String[] item = (String[])method.Invoke(o, null);
//注：method.Invoke(o, null)返回的是一個(gè)Object,如果你服務(wù)端返回的是DataSet,這里也是用(DataSet)method.Invoke(o, null)轉(zhuǎn)一下就行了,method.Invoke(0,null)這里的null可以傳調(diào)用方法需要的參數(shù),string[]形式的
foreach (string str in item)
Console.WriteLine(str);
//上面是根據(jù)WebService地址，模似生成一個(gè)代理類(lèi),如果你想看看生成的代碼文件是什么樣子，可以用以下代碼保存下來(lái)，默認(rèn)是保存在bin目錄下面
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代理類(lèi):
根據(jù)提供的wsdl生成webservice代理類(lèi)，然后在代碼里引用這個(gè)類(lèi)文件。
步驟：
1、在開(kāi)始菜單找到 Microsoft Visual Studio 2010 下面的Visual Studio Tools ， 點(diǎn)擊Visual Studio 命令提示(2010)，打開(kāi)命令行。
2、 在命令行中輸入： wsdl /language:c# /n:TestDemo /out:d:/Temp/TestService.cs http://jm1.services.gmcc.net/ad/Services/AD.asmx?wsdl
這句命令行的意思是：對(duì)最后面的服務(wù)地址進(jìn)行編譯，在D盤(pán)temp 目錄下生成testservice文件。
3、 把上面命令編譯后的cs文件，復(fù)制到我們項(xiàng)目中，在項(xiàng)目代碼中可以直接new 一個(gè)出來(lái)后，可以進(jìn)行調(diào)用。
貼出由命令行編譯出來(lái)的代碼：
