Square Number Patterns

Good day, I am having difficulties in this program
My Code is

using System;
class Pattern{
static void Main()
{
int rows, i, j, k;


Console.WriteLine("Enter the no. of rows: ");
rows = int.Parse(Console.ReadLine());

for (i = 1; i <= rows; i++)
{
 

  for (j = 1; j <= rows; j++)
  {
      k=i+j-1;
      if (k>rows){
      k=k-2;
      }
      Console.Write(k+ " ");
    
    
  }
  Console.WriteLine();
}
}
}

The output that I get is

123
232
323

The output that I want to get is
When I input 3
the output should be

123
232
321

When I input 4
the output should be

1234
2343
3432
4321

What seems to be wrong in my code? Thank you

>Solution :

    int count = int.Parse(Console.ReadLine());

    for (int i = 1; i <= count; i++)
    {
        string s = string.Empty;
        for (int j = i; j <= count + i - 1; j++)
        {
            int v;
            if (j > count)
            {
                v = count - (j - count);
            }
            else
            {
                v = j;
            }
            s += v;
        }
        Console.WriteLine(s);
    }
