Create your own exception class based on Exception

using System; using System.Collections; public class MyException : Exception {     public MyException( String reason, Exception inner ) :base( reason, inner ) {     } } public class MainClass {     static void Main() {         try {             try {                 ArrayList list = new ArrayList();                 list.Add( 1 );                 Console.WriteLine( "Item 10 = {0}", list[10] );             }             catch( ArgumentOutOfRangeException x ) {                 throw new MyException( "I'd rather throw this",x ) ;             }             finally {                 Console.WriteLine( "Cleaning up..." );             }         }         catch( Exception x ) {             Console.WriteLine( x );             Console.WriteLine( "Done" );         }     } } Cleaning up... MyException: I'd rather throw this --- System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index at System.Collections.ArrayList.get_Item(Int32 index) at MainClass.Main() --- End of inner exception stack trace --- at MainClass.Main() Done
