how do you pass a filename parameter to the main function

[abaker992]

Im trying to pass a filename parameter from the function to the main functio:

using System;
using System.Text;
using System.IO;

namespace Reaingthingyiles

{
	class program{
        

        public static void  checkit(StreamReader file)
        
	{
		StreamReader thingy = new StreamReader(thingy);
    	while(!thingy.EndOStream)
    	{
    		string line = thingy.ReadLine();
    		Console.WriteLine(line);

    	}
      
    }

    
    static void Main()
    {
    	checkit(new StreamReader (@"data.txt"));
       
    }
  }

}

Im failing horribly I need some direction.
