Question

I need method of lines, so that when you have method call Rows (4), a method prints four blank lines.

This is my code but it wont work, tell me what is wrong?

namespace something
{ 
  class Program 
  { 
    static void Main(string[] args) 
    { 
      Console.Write("give number: "); 
      int lines = int.Parse(Console.ReadLine()); 
      line(lines); 
      Console.WriteLine("lines end"); 
      Console.ReadKey(); 
    } 

    private static void line(int lines) 
    { 
       for (int i = 1; i <= lines; i++); 
       Console.WriteLine(" ");
    }
  } 
}

Remove ; at the end:

for (int i = 1; i <= lines; i++);
                                ^

In this case your Console.WriteLine(" "); called only once after loop finished. Loop doing nothing.
