How Can I Customize the Exit Code of a .NET Console Application?

Customizing the Exit Code of a Console Application in .NET

In .NET console applications, it may be necessary to specify a custom exit code for various purposes, such as indicating the success or failure of a test or providing additional information to the console consumer. To achieve this, three primary options are available:

1. Return Code from Main Method:

Declare the Main method of the console application to return an integer:

public static int Main(string[] args)
{
    // ... Your application code ...

    return exitCode; // Replace with the desired exit code
}

2. Environment.Exit(code):

Call the Environment.Exit method with the specified code:

Environment.Exit(exitCode);

3. Environment.ExitCode Property:

Set the ExitCode property of the Environment class:

Environment.ExitCode = exitCode; // Replace with the desired exit code

The choice of method depends on the specific requirements of the console application and the context in which it is used. For example, in a console-based test application, returning the exit code from the Main method may be suitable. In a production environment, using Environment.Exit or Environment.ExitCode property allows for more flexibility and control.
