Manually increments the reference counter on SafeHandle instances.
Assemblies: mscorlib (in mscorlib.dll)
System.Runtime.Handles (in System.Runtime.Handles.dll)
The method prevents the common language runtime from reclaiming memory used by a handle (which occurs when the runtime calls the ReleaseHandle method). You can use this method to manually increment the reference count on a SafeHandle instance. returns a Boolean value using a ref parameter (success) that indicates whether the reference count was incremented successfully. This allows your program logic to back out in case of failure. You should set success to false before calling . If success is true, avoid resource leaks by matching the call to with a corresponding call to DangerousRelease.
This method is intended for advanced users and must always be used carefully. To avoid leaking handle resources, always call this method inside a constrained execution region (CER), where a thread abort cannot interrupt processing.
