Return Value
An array of objects containing the return value and any by reference or out parameters for the XML Web service method.The following code example is an ASP.NET Web Form, which calls an XML Web service named Math. Within the EnterBtn_Click function, the Web Form starts and completes an asynchronous invocation of the Add XML Web service method.
The following code example is a proxy class generated by the Web Services Description Language tool (Wsdl.exe) for the Math XML Web service below. Within the EndAdd method of the proxy class, the EndInvoke method starts an asynchronous invocation of the Add XML Web service method.
namespace MyMath { [XmlRootAttribute("snippet1>",Namespace="http://MyMath/",IsNullable=false)] public ref class Math: public HttpGetClientProtocol { public: Math() { this->Url = "http://www.contoso.com/math.asmx"; } [HttpMethodAttribute(System::Web::Services::Protocols::XmlReturnReader::typeid, System::Web::Services::Protocols::UrlParameterWriter::typeid)] int Add( String^ num1, String^ num2 ) { array<Object^>^temp0 = {num1,num2}; return *dynamic_cast<int^>(this->Invoke( "Add", String::Concat( this->Url, "/Add" ), temp0 )); } IAsyncResult^ BeginAdd( String^ num1, String^ num2, AsyncCallback^ callback, Object^ asyncState ) { array<Object^>^temp1 = {num1,num2}; return this->BeginInvoke( "Add", String::Concat( this->Url, "/Add" ), temp1, callback, asyncState ); } int EndAdd( IAsyncResult^ asyncResult ) { return *dynamic_cast<int^>(this->EndInvoke( asyncResult )); } }; }
The following code example is the Math XML Web service, from which the above proxy class was created.
