C# 动态调用WebService
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Net; using System.Web.Services.Description; using System.CodeDom; using Microsoft.CSharp; using System.CodeDom.Compiler; using System.IO; namespace IBO.XJMYQP.Utility { public class WebServiceInvoke { public static object InvokeWebService(string url, string methodname) { return InvokeWebService("", url, null, methodname, null); } public static object InvokeWebService(string url, string methodname, object[] args) { return InvokeWebService("", url, null, methodname, args); } public static object InvokeWebService(string nameSpace, string url, string methodname, object[] args) { return InvokeWebService(nameSpace, url, null, methodname, args); } public static object InvokeWebService(string nameSpace, string url, string classname, string methodname, object[] args) { string @namespace = nameSpace; 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 = icc.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]; } } }
调用:
WebServiceInvoke.InvokeWebService(url, "GetServiceStatus");

另外一种动态方式: 记录一个.net平台下动态调用webservice的处理类(动态编辑请求soap信息)
实质上就是基于Http get/post请求来调用webservice
