1.url:http://localhost:8002/名称.asmx(asmx结尾)
2.需要引用的命名空间:System.Web.Services
3.调用代码:
public class DynamicWebService { /// <summary> /// 动态调用WebService /// </summary> /// <param name="url">地址</param> /// <param name="methodname">方法名</param> /// <param name="args">参数</param> /// <returns></returns> public static object InvokeWebService(string url, string methodname, object[] args) { return InvokeWebService(url, null, methodname, args); } /// <summary> /// 动态调用WebService /// </summary> /// <param name="url">地址</param> /// <param name="classname"></param> /// <param name="methodname">方法名</param> /// <param name="args">参数</param> /// <returns></returns> public static object InvokeWebService(string url, string classname, string methodname, object[] args) { string @namespace = "EnterpriseServerBase.WebService.DynamicWebCalling"; if ((classname == null) || (classname == "")) { classname = GetWsClassName(url); } try { //获取WSDL WebClient wc = new WebClient(); Stream stream = wc.OpenRead(url + "?wsdl"); ServiceDescription sd = ServiceDescription.Read(stream); ServiceDescriptionImporter sdi = new ServiceDescriptionImporter(); sdi.AddServiceDescription(sd, "", ""); CodeNamespace cn = new CodeNamespace(@namespace); //生成客户端代理类代码 CodeCompileUnit ccu = new CodeCompileUnit(); ccu.Namespaces.Add(cn); sdi.Import(cn, ccu); CSharpCodeProvider csc = new CSharpCodeProvider(); //ICodeCompiler icc = csc.CreateCompiler(); //设定编译参数 CompilerParameters cplist = new CompilerParameters(); cplist.GenerateExecutable = false; cplist.GenerateInMemory = true; cplist.ReferencedAssemblies.Add("System.dll"); cplist.ReferencedAssemblies.Add("System.XML.dll"); cplist.ReferencedAssemblies.Add("System.Web.Services.dll"); cplist.ReferencedAssemblies.Add("System.Data.dll"); //编译代理类 CompilerResults cr = csc.CompileAssemblyFromDom(cplist, ccu); if (true == cr.Errors.HasErrors) { System.Text.StringBuilder sb = new System.Text.StringBuilder(); foreach (System.CodeDom.Compiler.CompilerError ce in cr.Errors) { sb.Append(ce.ToString()); sb.Append(System.Environment.NewLine); } throw new Exception(sb.ToString()); } //生成代理实例,并调用方法 System.Reflection.Assembly assembly = cr.CompiledAssembly; Type t = assembly.GetType(@namespace + "." + classname, true, true); object obj = Activator.CreateInstance(t); System.Reflection.MethodInfo mi = t.GetMethod(methodname); return mi.Invoke(obj, args); } catch (Exception ex) { throw new Exception(ex.InnerException.Message, new Exception(ex.InnerException.StackTrace)); } } private static string GetWsClassName(string wsUrl) { string[] parts = wsUrl.Split('/'); string[] pps = parts[parts.Length - 1].Split('.'); return pps[0]; } }//end
3.调用示例:
string url = "http://localhost:8002/方法.asmx"; string[] args = new string[2]; args[0] = "123"; object result = DynamicWebService.InvokeWebService(url, "方法名", args);
