SafeHandle Class
Silverlight
This type can be used only by trusted applications. If you try to use its members in a partial-trust application, your code will throw a MethodAccessException exception. This type is security-critical, which restricts its use.
Namespace:
System.Runtime.InteropServices
Assembly: mscorlib (in mscorlib.dll)

The SafeHandle type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() ![]() | SafeHandle() | Initializes a new instance of the SafeHandle class using system defaults. |
![]() ![]() ![]() | SafeHandle(IntPtr, Boolean) | Initializes a new instance of the SafeHandle class with the specified invalid handle value. |
| Name | Description | |
|---|---|---|
![]() ![]() ![]() | Close | Security Critical. Marks the handle for releasing and freeing resources. |
![]() ![]() ![]() | DangerousAddRef | Security Critical. Manually increments the reference counter on SafeHandle instances. |
![]() ![]() ![]() | DangerousGetHandle | Returns the value of the handle field. |
![]() ![]() ![]() | DangerousRelease | Security Critical. Manually decrements the reference counter on a SafeHandle instance. |
![]() ![]() ![]() | Dispose() | Releases all resources used by the SafeHandle class. |
![]() ![]() ![]() | Dispose(Boolean) | Security Critical. Releases the unmanaged resources used by the SafeHandle class specifying whether to perform a normal dispose operation. |
![]() ![]() ![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() ![]() ![]() | Finalize | Frees all resources associated with the handle. (Overrides CriticalFinalizerObject::Finalize().) |
![]() ![]() ![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() ![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() ![]() | ReleaseHandle | When overridden in a derived class, executes the code required to free the handle. |
![]() ![]() ![]() | SetHandle | Sets the handle to the specified pre-existing handle. |
