How Do I Set Exit Codes in My .NET Console Applications?

Set Exit Codes in Console Applications with .NET

This article aims to guide you in defining the exit code of a console application created using .NET. Console applications are commonly used for testing or as components within larger programs.

Method 1: Returning Main with an int

Declare the Main method to return an integer, signifying the exit code. For example:

public static int Main(string[] args) {
    // Your application logic here...
    return 0;
}

Method 2: Utilizing Environment.Exit(code)

Call Environment.Exit(code) explicitly within your application. This method takes in an integer parameter that represents the exit code.

Environment.Exit(0);

Method 3: Setting Exit Code using Properties

Set the exit code using Environment.ExitCode = -1;. This property will be utilized if no other method has explicitly set the return code or used the previous options.

Variations based on Application Type

The choice of method may vary depending on the type of application you're developing. Here's an overview:

• Console Applications: Use Method 1 or Method 2.
• Service Applications: Method 3 is preferred.
• Web Applications: Exit codes are not typically used in ASP.NET applications.
