Thank for posting your code

Where is the question though?

I like this way:

public static int[,] TP2(int n)
{
int[,] arr = new int[n + 1, n + 1];
for (int r = 0; r < n + 1; ++r)
{
arr[r, 0] = 1;
arr[r, r] = 1;
if (r 0)
{
for (int c = 1; c < n; ++c)
arr[r, c] = arr[r - 1, c - 1] + arr[r - 1, c];
}
}
return arr;
}
