I have a simple code as following
// :c03:Assignment.cs

class Number
{
    public int i;
}

public class Assignment
{
    public static void Main()
    {
        Number n1 = new Number();
        Number n2 = new Number();

        n1.i = 9;
        n2.i = 47;

        System.Console.WriteLine("1: n1.i: " +n1.i + ", n2.i: " + n2.i);
        n1.i = n2.i;
        System.Console.WriteLine("2: n1.i: " +n1.i + ", n2.i: " + n2.i);
        n1.i = 27;
        System.Console.WriteLine("3: n1.i: " +n1.i + ", n2.i: " + n2.i);

    }
}
when I compiled and ran the exe file I just saw a flash and that was it. How can I make the dos windows to stay that I can see the result? Please help this beginner!

From the Debug menu select Start without Debugging (CTRL+F5) instead of Start (F5)

I compiled this by command line not from vs.net
c:\csc Assignment.cs
Then I did double click on Assignment.exe to view, but it was just flashing and disappeared..

This is not a C# or DevStudio issue. This will happen with any executable, which doesn't require user input.

Just open a command line first and execute the program from the command line.

Hope this helps,
Boris

Oh I got it. I just put the System.Console.ReadLine() right after System.Console.WriteLine(). Thanks for all inputs.
