Hinweise

The M:System.Runtime.InteropServices.SafeHandle.DangerousRelease method is the counterpart to M:System.Runtime.InteropServices.SafeHandle.DangerousAddRef(System.Boolean@). You should always match a call to the M:System.Runtime.InteropServices.SafeHandle.DangerousRelease method with a successful call to M:System.Runtime.InteropServices.SafeHandle.DangerousAddRef(System.Boolean@).

Warnung

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. In the same way that unmatched M:System.Runtime.InteropServices.SafeHandle.DangerousAddRef(System.Boolean@) calls can cause resource leaks, unmatched M:System.Runtime.InteropServices.SafeHandle.DangerousRelease calls can cause invalid handle states to become visible to other threads. Do not expose M:System.Runtime.InteropServices.SafeHandle.DangerousAddRef(System.Boolean@) or M:System.Runtime.InteropServices.SafeHandle.DangerousRelease calls to untrusted code.
