WebResponse.IDisposable.Dispose Method

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

When overridden in a derived class, releases all resources used by the WebResponse.

Namespace:  System.Net
Assembly:  System (in System.dll)

void IDisposable.Dispose()




Any attempt is made to access the method, when the method is not overridden in a descendant class.

Call IDisposable.Dispose when you are finished using the WebResponse. The IDisposable.Dispose method leaves the WebResponse in an unusable state. After calling IDisposable.Dispose, you must release all references to the WebResponse so the garbage collector can reclaim the memory that the WebResponse was occupying. For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose Method.

The IDisposable.Dispose method may behave differently when it is used in a Portable Class Library project. For more information, see API Differences in Portable Class Library.


Always call IDisposable.Dispose before you release your last reference to the WebResponse. Otherwise, the resources it is using will not be freed until the garbage collector calls the WebResponse object's Finalize method.
