Web Service动态调用.docx

完全动态处理,传入服务服务网址,方法名和参数即可. usingSystem; usingSystem.Net; usingSystem.IO; usingSystem.CodeDom; usingMicrosoft.CSharp; usingSystem.CodeDom.Compiler; usingSystem.Web.Services.Description; usingSystem.Web.Services.Protocols; namespaceHB.Common /*调用方式 *stringurl=/globalweather.asmx; *stringargs=newstring2; *args0=Hangzhou; *args1=China; *objectresult=WebServiceHelper.InvokeWebService(url,GetWeather,args); *Response.Write(result.ToString(); */ publicclassWebServiceHelper #regionInvokeWebService / /动态调用web服务 / /WSDL服务地址 /方法名 /参数 / publicstaticobjectInvokeWebService(stringurl,stringmethodname,objectargs) returnWebServiceHelper.InvokeWebService(url,null,methodname,args); / /动态调用web服务 / /WSDL服务地址 /类名 /方法名 /参数 / publicstaticobjectInvokeWebService(stringurl,stringclassname,stringmethodname,objectargs) stringnamespace=EnterpriseServerBase.WebService.DynamicWebCalling; if(classname=null)|(classname=) classname=WebServiceHelper.GetWsClassName(url); try /获取WSDL WebClientwc=newWebClient(); Streamstream=wc.OpenRead(url+?WSDL); ServiceDescriptionsd=ServiceDescription.Read(stream); ServiceDescriptionImportersdi=newServiceDescriptionImporter(); sdi.AddServiceDescription(sd,); CodeNamespacecn=newCodeNamespace(namespace); /生成客户端代理类代码 CodeCompileUnitccu=newCodeCompileUnit(); ccu.Namespaces.Add(cn); sdi.Import(cn,ccu); CSharpCodeProvidericc=newCSharpCodeProvider(); /设定编译参数 CompilerParameterscplist=newCompilerParameters(); 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 CompilerResultscr=icc.CompileAssemblyFromDom(cplist,ccu); if(true=cr.Errors.HasErrors) System.Text.StringBuildersb=newSystem.Text.StringBuilder(); foreach(System.CodeDom.Compiler.CompilerErrorceincr.Errors) sb.Append(ce.ToString(); sb.Append(System.Environment.NewLine); thrownewException(sb.ToString(); /生成代理实例，并调用方法 System.Reflection.Assemblyassembly=cr.CompiledAssembly; Typet=assembly.GetType(namespace+.+classname,true,true); objectobj=Activator.CreateInstance(t); System.Reflection.MethodInfomi=t.GetMethod(methodname); returnmi.Invoke(obj,args); /* PropertyInfopropertyInfo=type.GetProperty(propertyname); returnpropertyInfo.GetValue(obj,null); */ catch(Exceptionex) thrownewException(ex.InnerException.Message,newException(ex.InnerException.StackTrace); privatestaticstringGetWsClassName(stringwsUrl) stringparts=wsUrl.Split(/); stringpps=partsparts.Length-1.Split(.); returnpps0; #endregion 返回时如果不是字符串,即强制转换,如返回是DataSet,则 stringurl=/globalweather.asmx; stringa
