SafeHandle Constructor (IntPtr, Boolean)

 

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
)

Parameters

invalidHandleValue
Type: System::IntPtr

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

ownsHandle
Type: System::Boolean

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

Exception Condition
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.
