SafeHandle Constructor

Note: This constructor is new in the .NET Framework version 2.0.

Initializes a new instance of the SafeHandle class with the specified invalid handle value.

Namespace: System.Runtime.InteropServices
Assembly: mscorlib (in mscorlib.dll)

protected:
SafeHandle (
	IntPtr invalidHandleValue, 
	bool ownsHandle
)
protected SafeHandle (
	IntPtr invalidHandleValue, 
	boolean ownsHandle
)
protected function SafeHandle (
	invalidHandleValue : IntPtr, 
	ownsHandle : boolean
)

Parameters

invalidHandleValue

The value of an invalid handle (usually 0 or -1). Your implementation of IsInvalid should return true for this value.

ownsHandle

true to reliably let SafeHandle release the handle during the finalization phase; otherwise, false (not recommended).

Exception typeCondition

TypeLoadException

The derived class resides in an assembly without unmanaged code access permission.

If the ownsHandle parameter is false, ReleaseHandle is never called; thus, it is not recommended to use this parameter value as your code may leak resources.
