Running the script

The execution of a script is initiated by the Script.RunMain method. This method scans the types declared in the script (the list of types is available in the Script.Types property). It looks for a type that has a static method Main, and passes control to this method.

In the example below, running the script using the RunMain method will find the TestClass type, which has a static Main method, and execute it:

using FastScript.CSharp;

var text =
@"
namespace Test
{
    public class TestClass
    {
        public static void Main()
        {
            System.Console.WriteLine(""Hello!"");
        }
    }
}
";

var script = new CSharpScript();

if (script.Compile(text))
{
    script.RunMain();
}

If the Main method being run has parameters, their values must be specified in the RunMain method, for example:

    // script method:
    // public static void Main(int id, string text)

    script.RunMain(1, "abc");

The RunMain method returns the value returned by the Main method declared in the script. If the Main method is declared as void, the return value is undefined.

If the script has top level statements, a special class is created for them that has a static Main method. When the script is run using the RunMain method, this method receives control.

The following is an example of a script similar to the one described above that uses top level statements:

using FastScript.CSharp;

var text =
@"
System.Console.WriteLine(""Hello!"");
";

var script = new CSharpScript();

if (script.Compile(text))
{
    script.RunMain();
}
