ch07Ex02
when function main() load the string "nested index" in array eTypes,there will emerge a exception "IndexOutOfRangeException",I think the exception will go to the "catch(System.IndexOutOfRangeException)" inside the function main,but it goes to "catch" inside the function of Throwexception,
WHY?

Hello,

Could you post any code? Don't have the book.

Thanks,

Brian

I know now
Thank you all the same ,
the code as follows :

using System;

namespace Ch07Ex02
{
   /// <summary>
   /// Summary description for Class1.
   /// </summary>
   class Class1
   {
      static string[] eTypes = {"none", "simple", "index", "nested index"};

      static void Main(string[] args)
      {
         foreach (string eType in eTypes)
         {
            try
            {
               Console.WriteLine("Main() try block reached."); // Line 18
               Console.WriteLine("ThrowException(\"{0}\") called.", eType);
               // Line 19
               ThrowException(eType);
               Console.WriteLine("Main() try block continues."); // Line 21
            }
            catch (System.IndexOutOfRangeException e) // Line 23
            {
               Console.WriteLine("Main() System.IndexOutOfRangeException catch"
                  + " block reached. Message:\n\"{0}\"",
                  e.Message);
            }
            catch // Line 29,Ò»°ãµÄÒì³££¡
            {
               Console.WriteLine("Main() general catch block reached.");
            }
            finally
            {
               Console.WriteLine("Main() finally block reached.");
            }
            Console.WriteLine();
         }
      }

      static void ThrowException(string exceptionType)
      {
         // Line 43
         Console.WriteLine("ThrowException(\"{0}\") reached.", exceptionType);
         switch (exceptionType)
         {
            case "none" :
               Console.WriteLine("Not throwing an exception.");
               break; // Line 48
            case "simple" :
               Console.WriteLine("Throwing System.Exception.");
               throw (new System.Exception()); // Line 51
               break;
            case "index" :
               Console.WriteLine("Throwing System.IndexOutOfRangeException.");
               eTypes[4] = "error"; // Line 55
               break;
            case "nested index" :
               try // Line 58
               {
                  Console.WriteLine("ThrowException(\"nested index\") " +
                     "try block reached.");
                  Console.WriteLine("ThrowException(\"index\") called.");
                  ThrowException("index"); // Line 63
               }
               catch // Line 65
               {
                  Console.WriteLine("ThrowException(\"nested index\") general"
                     + " catch block reached.");

               }
               finally
               {
                  Console.WriteLine("ThrowException(\"nested index\") finally"
                     + " block reached.");
               }
               break;
         }


      }
   }
}

So what was the problem, or no problem at all?
