1、写一个webService（添加一个web服务）

在当前的网站上 右击-添加-新建项-web服务

然后在生成的类中添加调用的方法，如这里在WebService测试.asmx中添加一个test方法

1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Web; 5 using System.Web.Services; 6   7 namespace WebApplication1 8 { 9     /// 
10     /// WebService测试 的摘要说明11     /// 
12     [WebService(Namespace = "http://tempuri.org/")]13     [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]14     [System.ComponentModel.ToolboxItem(false)]15     // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消注释以下行。 16     // [System.Web.Script.Services.ScriptService]17     public class WebService测试 : System.Web.Services.WebService18     {19  20         [WebMethod]21         public string HelloWorld()22         {23             return "Hello World";24         }25         [WebMethod]26         public int test(int a,int b)27         {28             return a + b;29         }30     }31 }

可以允许该webService测试，在浏览器中输入webService地址

如：

可看到两个方法，一个是HelloWorld，另一个是刚才新建的test方法。

 

 

点击test可以进行测试

 

 

2、调用webService（添加服务引用）

在web项目中 右击-添加服务引用

再 地址栏 中输入webService地址，如上面的webService应输入

然后点转到，可搜索出对应的webService服务。

 

然后，再需要创建一个serviceClient，来调用webService方法（这里用winform程序简单写个按钮点击调用）

 

 

private void button1_Click(object sender, EventArgs e)         {            ServiceReference2.WebService测试SoapClient service = new ServiceReference2.WebService测试SoapClient();            int sum = service.test(1, 12);            MessageBox.Show(sum.ToString());         }

 

3动态调用webservice

 

封装一个WebServiceHelpel类，方便调用

 

1 public class WebServiceHelper 2     { 3         /// 
 4         /// 调用WebService 5         /// 
 6         /// 
     
      WebService地址 7         /// 
      
       方法名称 8         /// 
       
        参数列表 9         /// 
        10         public static object InvokeWebService(string wsUrl, string methodName, params object[] args)11         {12             return InvokeWebService(wsUrl, null, methodName, args);13         }14         /// 
        
15         /// 调用WebService16         /// 
17         /// 
        
         WebService地址18         /// 
         
          类名19         /// 
          
           方法名称20         /// 
           
            参数列表21         /// 
            22         public static object InvokeWebService(string wsUrl, string className, string methodName, params object[] args)23 {24 string @namespace = "EnterpriseServerBase.WebService.DynamicWebCalling";//ServiceBase.WebService.DynamicWebLoad或EnterpriseServerBase.WebService.DynamicWebCalling25             if (string.IsNullOrEmpty(className))26 {27 className = GetWsClassName(wsUrl);28 }29 try30 {31                 //获取WSDL32                 WebClient wc = new WebClient();33 Stream stream = wc.OpenRead(wsUrl + "?WSDL");34 ServiceDescription sd = ServiceDescription.Read(stream);35 ServiceDescriptionImporter sdi = new ServiceDescriptionImporter();36 sdi.AddServiceDescription(sd, "", "");37 CodeNamespace cn = new CodeNamespace(@namespace);38                 //生成客户端代理类代码39                 CodeCompileUnit ccu = new CodeCompileUnit();40 ccu.Namespaces.Add(cn);41 sdi.Import(cn, ccu);42 CSharpCodeProvider csc = new CSharpCodeProvider();43 ICodeCompiler icc = csc.CreateCompiler();44                 //设定编译参数45                 CompilerParameters cplist = new CompilerParameters();46 cplist.GenerateExecutable = false;47 cplist.GenerateInMemory = true;48 cplist.ReferencedAssemblies.Add("System.dll");49 cplist.ReferencedAssemblies.Add("System.XML.dll");50 cplist.ReferencedAssemblies.Add("System.Web.Services.dll");51 cplist.ReferencedAssemblies.Add("System.Data.dll");52                 //编译代理类53                 CompilerResults cr = icc.CompileAssemblyFromDom(cplist, ccu);54 if (true == cr.Errors.HasErrors)55 {56 System.Text.StringBuilder sb = new System.Text.StringBuilder();57 foreach (System.CodeDom.Compiler.CompilerError ce in cr.Errors)58 {59 sb.Append(ce.ToString());60 sb.Append(System.Environment.NewLine);61 }62 throw new Exception(sb.ToString());63 }64                 //生成代理实例，并调用方法65                 System.Reflection.Assembly assembly = cr.CompiledAssembly;66 Type t = assembly.GetType(@namespace + "." + className, true, true);67 object obj = Activator.CreateInstance(t);68 System.Reflection.MethodInfo mi = t.GetMethod(methodName);69 return mi.Invoke(obj, args);70 }71 catch (Exception ex)72 {73 throw new Exception(ex.InnerException.Message, new Exception(ex.InnerException.StackTrace));74 }75 }76 private static string GetWsClassName(string wsUrl)77 {78 string[] parts = wsUrl.Split('/');79 string[] pps = parts[parts.Length - 1].Split('.');80 return pps[0];81 }82 }
           
          
         
        
       
      
     

 

动态调用

static void Main(string[] args)        {            object o = WebServiceHelper.InvokeWebService("http://localhost:46391/WebService测试.asmx", "test",11,2);            Console.WriteLine(o.ToString());//结果输出13            Console.ReadKey();        }

 

动态调用webService带SoapHeader
