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 /// <summary> 10 /// WebService测试 的摘要说明 11 /// </summary> 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.WebService 18 { 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：http://localhost:46391/WebService测试.asmx
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http://localhost:46391/WebService测试.asmx
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 /// <summary> 4 /// 调用WebService 5 /// </summary> 6 /// <param name="wsUrl">WebService地址</param> 7 /// <param name="methodName">方法名称</param> 8 /// <param name="args">参数列表</param> 9 /// <returns></returns> 10 public static object InvokeWebService(string wsUrl, string methodName, params object[] args) 11 { 12 return InvokeWebService(wsUrl, null, methodName, args); 13 } 14 /// <summary> 15 /// 调用WebService 16 /// </summary> 17 /// <param name="wsUrl">WebService地址</param> 18 /// <param name="className">类名</param> 19 /// <param name="methodName">方法名称</param> 20 /// <param name="args">参数列表</param> 21 /// <returns></returns> 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.DynamicWebCalling 25 if (string.IsNullOrEmpty(className)) 26 { 27 className = GetWsClassName(wsUrl); 28 } 29 try 30 { 31 //获取WSDL 32 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
