Simple indexer example

The indexer is also called an attribute with parameters. The declaration method is very similar to the attribute.

 

 

Code

  //  Example of Indexer  
     Class  Group
{
  Public     Const     Int Maxnum  =     8  ;
  Private     String  [] Memeber;

  Public     String     This  [  Int  Idx] //  Define Indexer  
  {
  Get  {  Return  Memeber [idx];}
  Set  {Memeber [idx]  =  Value ;}
}

  Public  Group ()
{
Memeber  =    New     String  [Maxnum];
}
  Static     Void  Main (  String  [] ARGs)
{
  //  Note that group is an instance of a class. Because the indexer is defined, you can assign values and values like arrays.  
  Group  =    New  Group ();
Group [  0  ]  =     "  Zhang San  "  ;
Group [  1  ]  =     "  Li Si  " ;
Group [  2  ]  =     "  Wang Wu  "  ;
Group [  3  ]  =     "  Money 6  "  ;
Group [ 4  ]  =     "  Zhao Qi  "  ;
Group [  5  ]  =     "  Sun Ba  "  ;
  For  ( Int  I  =     0  ; I  <  Group. maxnum; I  ++  )
{
Console. writeline (group [I]);  //  Value  
  }
}
}
