创建方法
//动态调用web服务 public static object InvokeWebSer(string url,string @namespace, string classname, string methodname, object[] args) { System.Net.WebClient wc = new System.Net.WebClient(); string URL=string.Empty; if ((url.Substring(url.Length - 5, 5) != null) && ((url.Substring(url.Length - 5, 5).ToLower() != "?wsdl"))) URL = url + "?WSDL"; else URL = url; System.IO.Stream stream = wc.OpenRead(URL); System.Web.Services.Description.ServiceDescription sd = System.Web.Services.Description.ServiceDescription.Read(stream); System.Web.Services.Description.ServiceDescriptionImporter sdi = new System.Web.Services.Description.ServiceDescriptionImporter(); sdi.AddServiceDescription(sd, "", ""); System.CodeDom.CodeNamespace cn = new System.CodeDom.CodeNamespace(@namespace); System.CodeDom.CodeCompileUnit ccu = new System.CodeDom.CodeCompileUnit(); ccu.Namespaces.Add(cn); sdi.Import(cn, ccu); Microsoft.CSharp.CSharpCodeProvider csc = new Microsoft.CSharp.CSharpCodeProvider(); System.CodeDom.Compiler.CompilerParameters cplist = new System.CodeDom.Compiler.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"); System.CodeDom.Compiler.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()); } 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); }
调用
object obj = InvokeWebservice("http://localhost/GSP_WorkflowWebservice/common.asmx", "YouNamespace", // 欲调用的WebService的命名空间 "ServiceName", // 欲调用的WebService的类名(不包括命名空间前缀) "MethodName", // 欲调用的WebService的方法名 new object[]{"1"}); //传入参数
