How Can I Safely and Effectively Use Global Mutexes in C#?

C#global mutually exclusive body: safe and effective application guide

The Mutex class in C#is often misunderstood, especially when creating a global mutual mutual body. This article will explore a safe and effective model to use the global mutual mutual body.

Create the overall mutual body

First, obtain the application of the application from the program set attribute. Then define the mutually exclusive ID by connecting the prefix "Global" to the Guid. This ensures that the mutual body is unique on the entire machine.

Mutual body safety

In order to support the multi -user environment, please use the MutexaccessRule class to set up security rules. Given the Everyone group to complete the full control of permissions through the accountrologype.allow. Use

In the USING block, use the specified ID and security settings to create a new mutual body. Use the waitone () method to try to get a mutually exclusive handle. If it is not obtained within the specified time, Timeoutexception will be thrown. Please handle ABANDONEDMUTEXEPTIONS abnormalities elegantly, because they indicate that the mutual exclusion is abandoned in another process.

The release of mutual reproduction

Once you use the mutually exclusive body to complete the work, you must use the ReleaseMutex () method to release the mutually reprimanded handle. This ensures the correct resource cleaning.

code example

The following code contains these concepts:

This model follows the standards set in the original query, and effectively uses the global mutual mutual body in C#. The code is also optimized slightly, such as using string interpolation to improve readability.
