Try this - replace 20 with the length you need

	static void Main()
		{

			decimal[] values = {
								   11211105.99m,
								   0m, 
								   1m
							   };

			foreach (decimal x in values)
				Console.WriteLine("{0,20:$#,##0.00}", x);
			

			StringBuilder sb = new StringBuilder();
			sb.AppendFormat("{0,20:$#,##0.00}",  11211105.99m);
			Console.WriteLine(sb.ToString());
			Console.ReadLine();
		}
