Hi Nilesh ,
I think we can try following function:
public int FindLength(int num)
       {
           try
           {
               if (num < 0)
               {
                   num = num * (-1);
               }

               return num == 0 ? 1 : (int)Math.Floor(Math.Log10(num)) + 1;
           }
           catch (Exception ex)
           {
               throw ex;
           }
       }
Regards,
Mukesh Nayak
