    	string s;
    	public void Test() {
    		Console .WriteLine(“scanftree”);
    	}
    }
    

    create object for the class

    Scanftree obj;
    Obj=new scaftree();

    using System ;
    using System.Collection.Generic ;
    using System.Linq ;
    using System .Text;
    namespace Oopprograme {
    	class Class1 {
    		public int year = 2011;
    		public string s= “scanftree”;
    		static void Main() {
    			Class1 cls=new Class1();
    			Console.WriteLine (“--------”+cls.s+”-------“);
    			Console.WriteLine(“*******”+cls.year+”*********);
    			Console.Read();
    		}
