HttpClient.Close Method

Definition

Closes the HttpClient instance and releases allocated resources. For programming guidance for the HttpClient class, and code examples, see the HttpClient conceptual topic.

public:
 virtual void Close() = Close;

void Close();

function close()

' This member is not implemented in VB.NET

Implements

M:Windows.Foundation.IClosable.Close M:System.IDisposable.Close

Remarks

The Close method releases allocated resources used by the HttpClient instance. The Close method can manage the lifetime of system resources (the underlying socket and memory for the HttpClient, 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 HttpClient 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.
