using System;
using System.Globalization;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      // Create a read-write NumberFormatInfo object for the current culture.
      NumberFormatInfo numberInfo = NumberFormatInfo.CurrentInfo.Clone() as NumberFormatInfo;
      decimal value = -0.1324m;

      // Assign each possible value to the CurrencyNegativePattern property.
      for (int ctr = 0; ctr <= 11; ctr++)
      {
         numberInfo.PercentNegativePattern = ctr;
         outputBlock.Text += String.Format("{0,2}: {1}\n", ctr, 
                                           value.ToString("P", numberInfo));
      }
