How to Safely and Robustly Implement Global Mutexes in C#?

C# Class provides a mechanism that provides mutual exclusion between multiple threads or processes to synchronize visits to shared resources. However, the global mutual lock across the entire machine needs to be handled carefully to avoid common traps.

In order to create a strong global mutual lock mode in C#, please consider the following: Mutex

Using the unique mutual lock ID:

Use the global unique identifier (Guid) stored in the

file to identify your application. This ensures that the mutual lock ID is unique on all machines.
1. Set appropriate security permissions: Use the AssemblyInfo.cs Class configuration access rules to grant all users to fully control the permissions to ensure that other processes can interact with mutual locks.
2. Use the lock and Try-Finally structure: The code block that needs to be exclusively accessible to the access resource is included in the lock. Use Try-Finally block to ensure that it is always released, even if abnormalities occur. MutexSecurity Processing the abandoned mutual lock:
If the process of the process is terminated, the mutual lock may be abandoned. Treatment of this situation by capturing and obtaining mutual locks like a new mutual lock.
3. Timeout: In order to prevent potential dead locks, please consider the timeout mechanism, instead of waiting indefinitely to obtain mutual locks.
4. By following these best practices, you can ensure that your global mutual lock is safe, strong and meet your application requirements. The provided example code demonstrates a comprehensive implementation of these guidelines.
