| Name | Description | |
|---|---|---|
![]() | SafePipeHandle(IntPtr, Boolean) | Initializes a new instance of the SafePipeHandle class. |
| Name | Description | |
|---|---|---|
![]() | IsClosed | Gets a value indicating whether the handle is closed.(Inherited from SafeHandle.) |
![]() | IsInvalid | Gets a value that indicates whether the handle is invalid.(Inherited from SafeHandleZeroOrMinusOneIsInvalid.) |
| Name | Description | |
|---|---|---|
![]() | Close() | Marks the handle for releasing and freeing resources.(Inherited from SafeHandle.) |
![]() | DangerousAddRef(Boolean) | Manually increments the reference counter on SafeHandle instances.(Inherited from SafeHandle.) |
![]() | DangerousGetHandle() | Returns the value of the handle field.(Inherited from SafeHandle.) |
![]() | DangerousRelease() | Manually decrements the reference counter on a SafeHandle instance.(Inherited from SafeHandle.) |
![]() | Dispose() | Releases all resources used by the SafeHandle class.(Inherited from SafeHandle.) |
![]() | Equals(Object) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetType() | |
![]() | SetHandleAsInvalid() | Marks a handle as no longer used.(Inherited from SafeHandle.) |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
This class is derived from SafeHandleZeroOrMinusOneIsInvalid. A value of 0 or -1 is an invalid pipe handle.

This type implements the IDisposable interface. When you have finished using the type, you should dispose of it either directly or indirectly. To dispose of the type directly, call its Dispose method in a try/catch block. To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). For more information, see the “Using an Object that Implements IDisposable” section in the IDisposable interface topic. |
