class Microsoft.Win32.SafeHandles.CriticalHandleZeroOrMinusOneIsInvalid
Assembly: System.Runtime
Inheritance: object → System.Runtime.ConstrainedExecution.CriticalFinalizerObject → System.Runtime.InteropServices.CriticalHandle → CriticalHandleZeroOrMinusOneIsInvalid
Implemented Interfaces
- System.IDisposable Implemented by: CriticalHandle
Provides a base class for Win32 critical handle implementations in which the value of either 0 or -1 indicates an invalid handle.
Fields and Constants
protected
nint
handle
Specifies the handle to be wrapped.
Properties
public
bool
IsInvalid
Gets a value that indicates whether the handle is invalid.
public
bool
IsClosed
Gets a value indicating whether the handle is closed.
Methods
public
void
Close()
Inherited from System.Runtime.InteropServices.CriticalHandle
Marks the handle for releasing and freeing resources.
public
void
Dispose()
Inherited from System.Runtime.InteropServices.CriticalHandle
Releases all resources used by the <see cref="T:System.Runtime.InteropServices.CriticalHandle" /> .
protected
void
Dispose(bool disposing)
Inherited from System.Runtime.InteropServices.CriticalHandle
Releases the unmanaged resources used by the <see cref="T:System.Runtime.InteropServices.CriticalHandle" /> class specifying whether to perform a normal dispose operation.
disposing
<see langword="true" /> for a normal dispose operation; <see langword="false" /> to finalize the handle.
protected
void
Finalize()
Inherited from System.Runtime.InteropServices.CriticalHandle
Frees all resources associated with the handle.
protected
bool
ReleaseHandle()
Inherited from System.Runtime.InteropServices.CriticalHandle
When overridden in a derived class, executes the code required to free the handle.
Returns <see langword="true" /> if the handle is released successfully; otherwise, in the event of a catastrophic failure, <see langword="false" /> . In this case, it generates a releaseHandleFailed Managed Debugging Assistant.
protected
void
SetHandle(nint handle)
Inherited from System.Runtime.InteropServices.CriticalHandle
Sets the handle to the specified pre-existing handle.
handle
The pre-existing handle to use.
public
void
SetHandleAsInvalid()
Inherited from System.Runtime.InteropServices.CriticalHandle
Marks a handle as invalid.
public
bool
Equals(object obj)
Inherited from object
Determines whether the specified object is equal to the current object.
Returns <see langword="true" /> if the specified object is equal to the current object; otherwise, <see langword="false" /> .
obj
The object to compare with the current object.
public
int
GetHashCode()
Inherited from object
Serves as the default hash function.
Returns A hash code for the current object.
public
System.Type
GetType()
Inherited from object
Gets the <see cref="T:System.Type" /> of the current instance.
Returns The exact runtime type of the current instance.
protected
object
MemberwiseClone()
Inherited from object
Creates a shallow copy of the current <see cref="T:System.Object" /> .
Returns A shallow copy of the current <see cref="T:System.Object" /> .
public
string
ToString()
Inherited from object
Returns a string that represents the current object.
Returns A string that represents the current object.
