1、定義webservice調用類

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Net;using System.IO;using System.ServiceModel.Description;using System.Web.Services.Description;using System.CodeDom;using Microsoft.CSharp;using System.CodeDom.Compiler;using ServiceDescription = System.Web.Services.Description.ServiceDescription;namespace WebService測試{    public class WebServiceInvoke    {        #region InvokeWebService        /// <summary>        /// 擷取WebService類型        /// </summary>        /// <param name="wsUrl">WebService地址</param>        /// <returns></returns>        private static string GetWsClassName(string wsUrl)        {            string[] parts = wsUrl.Split(‘/‘);            string[] pps = parts[parts.Length - 1].Split(‘.‘);            return pps[0];        }        /// <summary>        /// 調用WebService        /// </summary>        /// <param name="wsUrl">WebService地址</param>        /// <param name="methodName">方法名稱</param>        /// <param name="args">參數列表</param>        /// <returns></returns>        public static object InvokeWebService(string wsUrl, string methodName, object[] args)        {            return InvokeWebService(wsUrl, null, methodName, args);        }        /// <summary>        /// 調用WebService        /// </summary>        /// <param name="wsUrl">WebService地址</param>        /// <param name="className">類名</param>        /// <param name="methodName">方法名稱</param>        /// <param name="args">參數列表</param>        /// <returns></returns>        public static object InvokeWebService(string wsUrl, string className, string methodName, object[] args)        {            string @namespace = "EnterpriseServerBase.WebService.DynamicWebCalling";            if ((className == null) || (className == ""))            {                className = GetWsClassName(wsUrl);            }            try            {                //擷取WSDL                WebClient wc = new WebClient();                Stream stream = wc.OpenRead(wsUrl + "?wsdl");                ServiceDescription sd = ServiceDescription.Read(stream);                ServiceDescriptionImporter sdi = new ServiceDescriptionImporter();                sdi.AddServiceDescription(sd, "", "");                CodeNamespace cn = new CodeNamespace(@namespace);                //產生用戶端代理類代碼                CodeCompileUnit ccu = new CodeCompileUnit();                ccu.Namespaces.Add(cn);                sdi.Import(cn, ccu);                CSharpCodeProvider csc = new CSharpCodeProvider();                ICodeCompiler icc = csc.CreateCompiler();                //設定編譯參數                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 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());                }                //組建代理程式執行個體，並調用方法                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);                return mi.Invoke(obj, args);            }            catch (Exception ex)            {                throw new Exception(ex.InnerException.Message, new Exception(ex.InnerException.StackTrace));            }        }        #endregion    }}

2、定義調用方法

public void ReWebServiceResult(object[] Jsonstri)        {            try            {                string url = "http://localhost:25064/Client/IWSLedgerService.asmx";                //string url = "http://localhost/WebService/Service.asmx";                //string[] args = new string[1];                //args[0] = "P000001";                object result = WebServiceInvoke.InvokeWebService(url, "LogisticsLedgerService", Jsonstri);//LogisticsLedgerService  為需要調用的webservice方法            }            catch (Exception ex)            {            }        }
