C#動態調用WebService?

object item = InvokeWebService(this._webServicesUrl, "HelloWorld", new object[] { "參數" });

public static object InvokeWebService(string url, string methodname, object[] args){return InvokeWebService(url, null, methodname, args);}public static object InvokeWebService(string url, string classname, string methodname, object[] args){string @namespace = "ServiceBase.WebService.DynamicWebLoad";if (classname == null || classname == ""){classname = GetClassName(url.Replace("?wsdl", ""));}//獲取服務描述語言(WSDL)WebClient wc = new WebClient();Stream stream = wc.OpenRead(url);ServiceDescription sd = ServiceDescription.Read(stream);ServiceDescriptionImporter sdi = new ServiceDescriptionImporter();sdi.AddServiceDescription(sd, "", "");CodeNamespace cn = new CodeNamespace(@namespace);//生成客戶端代理類代碼CodeCompileUnit ccu = new CodeCompileUnit();ccu.Namespaces.Add(cn);sdi.Import(cn, ccu);Microsoft.CSharp.CSharpCodeProvider csc = new Microsoft.CSharp.CSharpCodeProvider();ICodeCompiler icc = csc.CreateCompiler();//設定編譯器的參數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");//編譯代理類CompilerResults cr = icc.CompileAssemblyFromDom(cplist, ccu);if (true == cr.Errors.HasErrors){System.Text.StringBuilder sb = new StringBuilder();foreach (CompilerError ce in cr.Errors){sb.Append(ce.ToString());sb.Append(System.Environment.NewLine);}throw new Exception(sb.ToString());}//生成代理實例,并調用方法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);System.Reflection.MethodInfo mt = t.GetMethod("set_Url");mt.Invoke(obj, new object[] { url });object result;try{result = mi.Invoke(obj, args);}catch (Exception ex){result = ex.InnerException;}return result;}private static string GetClassName(string url){string[] parts = url.Split('/');string[] pps = parts[parts.Length - 1].Split('.');return pps[0];} View Code
