Question

The frame method, which has two parameters, the frame length and height. The main program lines i used

String s = Frame (5, 4);
Console.WriteLine (s);

which prints following:

*****
*   *
*   *
*****

this is very easy without method, but with method this seems to be difficult, any ideas?
This is my last question for today. 🙂

using System;
using System.Collections.Generic;
using System.Linq;

class Sample {
    static string Frame(int width, int height){
        var wk = new List<string>();
        string term = new String('*', width);
        string inner = "*" + new String(' ', width-2) + "*";
        wk.Add(term);
        wk.AddRange(Enumerable.Repeat(inner, height-2));
        wk.Add(term);
        return String.Join("\n", wk);

    }
    static void Main(){
        string s = Frame (5, 4);
        Console.WriteLine (s);
    }
}
