While solving star patterns, just focus on gaps,
In your problem, if column>=Row, means (j>=i) then it has to print j otherwise not.
public class Program
{
  public static void Main()
  {
    int n=4; // whatever is user input
     for (int i=1;i<=n;i++) // rows
    {
     for (int j=n;j>=1;j--) // columns
          {
             if(j>=i) // Gaps where we don't want to print
                {
                    Console.Write(j);  // same line
                 }
           }
        Console.WriteLine();  // next line
     }
  }
}

static void printPattern(int n)
{
// Loop to print desired pattern
int curr_Index = n;
for (int line_no = n; line_no > 0;)
{
// If current index count is Greater than 0
// current line number
if (curr_Index > 0)
{
Console.Write(curr_Index + (n - line_no));
curr_Index--;
continue;
}

// Else time to print a new line
if (curr_Index <= 0)
{
Console.WriteLine();
line_no--;
curr_Index = line_no;
}
}
}

Desired Output with single Loop Only

public static void Main()
{
Console.Write("Enter Number of Rows :");
int rows = Convert.ToInt32(Console.ReadLine());
for (int i = rows; i >= 1; i--)
{
//j<=i //let rows = 5
/* first row (0 to 5) = 5 numbers (1,2,3,4,5)
* second row (0 to 4) = 4 numbers (1,2,3,4)
* third row (0 to 3) = 3 numbers (1,2,3)
* and so on
*/
//calculate stars for each row one by one
for (int j = 1; j <= i; j++)
{
Console.Write(j + " ");
}
Console.WriteLine();
}
Console.ReadLine();
}

Enter Number of Rows: 5
