WaitHandle.Handle Property (System.Threading)

.NET Framework Class Library

WaitHandle..::.Handle Property

Note: This API is now obsolete. The non-obsolete alternative is SafeWaitHandle.

Gets or sets the native operating system handle.

Namespace: System.Threading
Assembly: mscorlib (in mscorlib.dll)

<ObsoleteAttribute("Use the SafeWaitHandle property instead.")> _
Public Overridable Property Handle As IntPtr

[ObsoleteAttribute("Use the SafeWaitHandle property instead.")]
public virtual IntPtr Handle { get; set; }

[ObsoleteAttribute(L"Use the SafeWaitHandle property instead.")]
public:
virtual property IntPtr Handle {
	IntPtr get ();
	void set (IntPtr value);
}

[<ObsoleteAttribute("Use the SafeWaitHandle property instead.")>]
abstract Handle : IntPtr with get, set
[<ObsoleteAttribute("Use the SafeWaitHandle property instead.")>]
override Handle : IntPtr with get, set

Property Value

Type: System..::.IntPtr
An IntPtr representing the native operating system handle. The default is the value of the InvalidHandle field.

Remarks

Assigning a new value to the Handle property does not close the previous handle. This can result in a leaked handle.

Do not use this property in the .NET Framework version 2.0 or later; use the SafeWaitHandle property instead. Setting this property to a valid handle also sets the SafeWaitHandle property, but setting it to InvalidHandle can result in a leaked handle.
