TextReader.Dispose Method

Definition

Namespace:

System.IO

Assembly:

System.Runtime.dll

Releases all resources used by the TextReader object.

Overloads

Dispose()	Releases all resources used by the TextReader object.
Dispose(Boolean)	Releases the unmanaged resources used by the TextReader and optionally releases the managed resources.

Dispose()

Source:

TextReader.cs

Releases all resources used by the TextReader object.

public:
 virtual void Dispose();

public void Dispose ();

abstract member Dispose : unit -> unit
override this.Dispose : unit -> unit

Public Sub Dispose ()

Implements

Dispose()

Remarks

Call Dispose when you are finished using the TextReader. The Dispose method leaves the TextReader in an unusable state. After calling Dispose, you must release all references to the TextReader so the garbage collector can reclaim the memory that the TextReader was occupying.

For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose Method.

Note

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

Dispose(Boolean)

Source:

TextReader.cs

Releases the unmanaged resources used by the TextReader and optionally releases the managed resources.

protected:
 virtual void Dispose(bool disposing);

protected virtual void Dispose (bool disposing);

abstract member Dispose : bool -> unit
override this.Dispose : bool -> unit

Protected Overridable Sub Dispose (disposing As Boolean)

Parameters

disposing

Boolean

true to release both managed and unmanaged resources; false to release only unmanaged resources.

Remarks

This method is called by the public Dispose() method and the Finalize() method, if it has been overridden. Dispose() invokes this method with the disposing parameter set to true. Finalize invokes this method with disposing set to false.

When the disposing parameter is true, this method releases all resources held by any managed objects that this TextReader references. This method invokes the Dispose method of each referenced object.

Notes to Inheritors

Dispose can be called multiple times by other objects. When overriding this method, be careful not to reference objects that have been previously disposed of in an earlier call to Dispose. For more information about how to implement this method, see Implementing a Dispose Method.
