In class2, you are calling Console.WriteLine(c1.inf1());.

So class1.inf1 should return a string as you are trying to output it to the console.

However, class1.inf1() recursively calls itself with no exit and does not return a string.

So I think this may be what you are trying to accomplish:

protected internal string inf1()
{
    return "
......inf1() 
";
}
