Request Message. Close Method
public: virtual void Close() = Close;
// This member is not implemented in C#
' This member is not implemented in VB.NET
The Close method releases allocated resources used by the HttpRequestMessage instance. The Close method can manage the lifetime of system resources (memory for the HttpRequestMessage, for example) used by a Windows Runtime object.
In the .NET Framework 4.5, this method projects as the Dispose method. In Visual C++ component extensions (C++/CX), this method projects as the destructor (delete operator).
Apps written in C++ or CX don't have a Close method since these apps can destroy the object. In C++ and CX, objects are released when they fall out of program scope or as part of the destructor (delete operator) for the object.
