In this short article, we would like to show how to return the status code from the Main function in C#.

Quick solution:

xxxxxxxxxx
 
// put at the end of the Main()
​
Environment.Exit(code);
​
// e.g.
Environment.Exit(2);

Practical example

Edit

xxxxxxxxxx
 
using System;
​
public class TestClass
{
    public static void Main()
    {
        Environment.Exit(2); // 0 usually means the program ended successfully
                             //   other numbers describe error code
                             // e.g. 
                             //   here we returned error with code 2
    }
}

Example output:

xxxxxxxxxx
 
The program '[4476] ConsoleApp1.exe' has exited with code 2 (0x2).

Above code is equivalent to the following c++ / cpp code version:

xxxxxxxxxx
 
using namespace std;
​
int main()
{
    return 2; // 0 usually means the program ended successfully
              //   other numbers describe error code
              // e.g. 
              //   here we returned error with code 2
}
