C动态调用WebService服务方法

1、C#动态调用WebService服务方法调用举例：string xmlTxt = WebServiceHelper.InvokeWebService(interFaceUrl, MethodName, Objpara).ToString();代码：using System;using System.Collections.Generic;using System.Text;using System.IO;using System.Net;using System.CodeDom;using System.CodeDom.Compiler;using System.Web.Services.De

2、scription;using Microsoft.CSharp;namespace HDSS.Finance.Common public static class WebServiceHelper private static Dictionary _DicInvokeType; public static Dictionary DicInvokeType get if (_DicInvokeType = null) _DicInvokeType = new Dictionary(); return _DicInvokeType; set _DicInvokeType = value; /

3、/ 动态调用WebService / / WebService地址 / 方法名(模块名) / 参数列表,无参数为null / object public static object InvokeWebService(string url, string methodname, params object args) return InvokeWebService(url, null, methodname, args); public static object InvokeWebService(string url, string classname, string methodname,

4、params object args) return InvokeWebService(url, WebServer, classname, methodname, args); / / 动态调用WebService / / WebService地址 / 类名 / 方法名(模块名) / 参数列表 / object public static object InvokeWebService(string url, string namespace, string classname, string methodname, params object args) url = url.Trim();

5、 WebInvokePar tWebInkove = new WebInvokePar(); System.Reflection.MethodInfo mi; if (DicInvokeType.ContainsKey(url) tWebInkove = DicInvokeTypeurl; if (tWebInkove != null) mi = tWebInkove.WebType.GetMethod(methodname);/【11】 if (mi != null) return mi.Invoke(tWebInkove.AssInstance, args); /string namesp

7、onImporter sdi = new ServiceDescriptionImporter();/【3】 sdi.AddServiceDescription(sd, , ); CodeNamespace cn = new CodeNamespace(namespace);/【4】 /生成客户端代理类代码 CodeCompileUnit ccu = new CodeCompileUnit();/【5】 ccu.Namespaces.Add(cn); sdi.Import(cn, ccu); CSharpCodeProvider csc = new CSharpCodeProvider();/

8、【6】 ICodeCompiler icc = csc.CreateCompiler();/【7】 /设定编译器的参数 CompilerParameters cplist = new CompilerParameters();/【8】 cplist.GenerateExecutable = false; cplist.GenerateInMemory = true; cplist.ReferencedAssemblies.Add(System.dll); cplist.ReferencedAssemblies.Add(System.XML.dll); cplist.ReferencedAsse

9、mblies.Add(System.Web.Services.dll); cplist.ReferencedAssemblies.Add(System.Data.dll); /编译代理类 CompilerResults cr = icc.CompileAssemblyFromDom(cplist, ccu);/【9】 if (true = cr.Errors.HasErrors) System.Text.StringBuilder sb = new StringBuilder(); foreach (CompilerError ce in cr.Errors) sb.Append(ce.ToS

10、tring(); 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; var tps = assembly.GetTypes(); Type t = null; if (tps.Length = 1) t = tps0; else t = assembly.GetType(namespace + . + classname, true, true); ob

11、ject obj = Activator.CreateInstance(t);/【10】 mi = t.GetMethod(methodname);/【11】 if (mi = null) return ; tWebInkove.AssInstance = obj; tWebInkove.WebType = t; tWebInkove.WebUrl = url; DicInvokeTypeurl = tWebInkove; return mi.Invoke(obj, args); private static string GetClassName(string url) /假如URL为http:/localhost/InvokeService/Service1.asmx /最终的返回值为 Service1 string parts = url.Split(/); str
