Example

using System;

namespace Samples
{
  public class FormatExceptionSample
  {
    public static void Main()
    {
      try
      {
        string s = "12.34";
        int i = Convert.ToInt32(s);
      }
      catch(FormatException e)
      {
        Console.WriteLine("Exception: {0}", e);
      }
    }
  }
}

The output is

   at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info)
   at System.Convert.ToInt32(String value)
