How Can I Capture Console Exit Events in C# Multithreaded Applications?

Managing Console Application Termination in C# with Multiple Threads

In multithreaded C# console applications, ensuring clean program shutdown is critical for resource management. Unfortunately, .NET doesn't offer a direct event for console exit handling. This necessitates alternative methods.

One effective solution leverages the Windows API function SetConsoleCtrlHandler via DllImport. This allows registration of a custom handler function triggered by specific console control signals.

Here's an illustrative implementation:

<code class="language-csharp">using System;
using System.Runtime.InteropServices;

// ... (rest of the code remains the same)</code>

This code snippet demonstrates how to utilize SetConsoleCtrlHandler to capture CTRL_C_EVENT, CTRL_LOGOFF_EVENT, CTRL_SHUTDOWN_EVENT, and CTRL_CLOSE_EVENT. The Handler function is executed when any of these events occur.

Important Consideration: This method's reliability might be compromised on Windows 7, as noted in related discussions. Further investigation may be required for optimal compatibility across different Windows versions.
