导读：代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Net;
using System.IO;
using System.Web.Services.Description;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Net;
using System.IO;
using System.Web.Services.Description;

代码如下: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Net; using System.IO; using System.Web.Services.Description; using System.CodeDom; using Microsoft.CSharp; using System.CodeDom.Compiler; using System.Reflection; namespace HTTPS { public class WSHelper { /// < summary> /// 动态调用web服务 /// < /summary> /// < param name="url">WSDL服务地址< /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 WSHelper.InvokeWebService(url, null, methodname, args); } /// < summary> /// 动态调用web服务 /// < /summary> /// < param name="url">WSDL服务地址< /param> /// < param name="classname">类名< /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 = WSHelper.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 icc = new CSharpCodeProvider(); //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); （编辑：聊城站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
