Hello everyone,

I am generating controls like textbox ,labels dynamically for different subjects which are further dependent on the standard selected now i have to cross check that which controls are generated like if i select standard 9 then controls of subjects would be of Maths, science etc and if i select 11th science then it would be physics , chemistry etc. for that i have taken an bool[] b array in which i specify that b[0] is for Maths and if maths textbox is generated then it is set to true else it is false.

Now what i need is can i have array like this b["Maths"]=true OR b["M"]=true?? i.e. is it possible to traverse or iterate to an array using string or character ??

Please let me know if it is possible ...

Thanks & Regards,
Krunal Panchal

Such indexing functionality is achieved through one of the following generic classes:

System.Collections.Generic.Dictionary<TKey, TValue>;
http://msdn.microsoft.com/en-us/library/xfhwa508.aspx[^];
System.Collections.Generic.SortedDictionary<TKey, TValue>;
http://msdn.microsoft.com/en-us/library/f7fta44c.aspx[^];
System.Collections.Generic.SortedList<TKey, TValue>;
http://msdn.microsoft.com/en-us/library/ms132319.aspx[^].

These classes are very similar in usage and different mostly in the trade-off between performance and redundancy. The Dictionary class is the most often used. Please see the MSDN help pages referenced above for further detail.

[EDIT]

The traversal of the whole collection can be done through foreach; and the loop variable has the type System.Collections.Generic.KeyValuePair<TKey, TValue>, http://msdn.microsoft.com/en-us/library/5tbh8a42.aspx[^].
