HttpRequestMessage.Close Method

Definition

Closes the HttpRequestMessage instance and releases allocated resources.

public:
 virtual void Close() = Close;
void Close();
// This member is not implemented in C#
function close()
' This member is not implemented in VB.NET

Implements

System.IDisposable.Close

Remarks

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 JavaScript, C#, or VB.NET use garbage collection to release resources. So the HttpRequestMessage object and associated resources don't get released until the garbage collection pass runs. The Close method allows an app to release these resources early rather than waiting for the object to be released by garbage collection.

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.
