C# Language Tutorial => Creating a new program using Mono

Example

First install Mono by going through the install instructions for the platform of your choice as described in their installation section.

Mono is available for Mac OS X, Windows and Linux.

After installation is done, create a text file, name it HelloWorld.cs and copy the following content into it:

public class Program
{
    public static void Main()
    {
        System.Console.WriteLine("Hello, world!");
        System.Console.WriteLine("Press any key to exit..");
        System.Console.Read();
    }
}

If you are using Windows, run the Mono Command Prompt which is included in the Mono installation and ensures that the necessary environment variables are set. If on Mac or Linux, open a new terminal.

To compile the newly created file, run the following command in the directory containing HelloWorld.cs:

mcs -out:HelloWorld.exe HelloWorld.cs

The resulting HelloWorld.exe can then be executed with:

mono HelloWorld.exe

which will produce the output:

Hello, world!   
Press any key to exit..
