.net 如何调用webservice

Answer 1

.net 调用webservice using System.Collections.Generic;//using System.Linq;using System.Text;using System.IO;using System.Net;using System.CodeDom;using System.CodeDom.Compiler;using System.Web.Services.Description;using Microsoft.CSharp;namespace NetbankTMP{ public static class WebServiceHelper { /// <summary> /// 动态调用WebService /// </summary> /// <param name="url">WebService地址</param> /// <param name="methodname">方法名(模块名)</param> /// <param name="args">参数列表,无参数为null</param> /// <returns>object</returns> public static object InvokeWebService(string url, string methodname, object[] args) { return InvokeWebService(url, null, methodname, args); } /// <summary> /// 动态调用WebService /// </summary> /// <param name="url">WebService地址</param> /// <param name="classname">类名</param> /// <param name="methodname">方法名(模块名)</param> /// <param name="args">参数列表</param> /// <returns>object</returns> public static object InvokeWebService(string url, string classname, string methodname, object[] args) { string @namespace = "wangsx.test"; if (classname == null || classname == "") { classname = WebServiceHelper.GetClassName(url); } //获取服务描述语言(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();// //设定编译器的参数 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 StringBuilder(); foreach (CompilerError ce in cr.Errors) { sb.Append(ce.ToString()); sb.Append(System.Environment.NewLine); } throw new System.Exception(sb.ToString()); } //生成代理实例,并调用方法 System.Reflection.Assembly assembly = cr.CompiledAssembly; System.Type t = assembly.GetType(@namespace + "." + classname, true, true); object obj = System.Activator.CreateInstance(t);// System.Reflection.MethodInfo mi = t.GetMethod(methodname);// return mi.Invoke(obj, args); } private static string GetClassName(string url) { //假如URL为"<a href="http://localhost/InvokeService/Service1.asmx" target="_blank">http://localhost/InvokeService/Service1.asmx</a>" //最终的返回值为 Service1 string[] parts = url.Split('/'); string[] pps = parts[parts.Length - 1].Split('.'); return pps[0]; } }}

1. 右键你的网站-〉添加服务引用-〉然后输入webservice的地址。

2. 之后，你就可以用对象来操作你的webservice了
