Dictionary<TKey,object> modify indexer to cast before returning value

I've seen this in a question: :

edit: type's are known before adding to dictionary 

You could use Dictionary<string, object>, then you'd need to cast the results:

int no = 1;       
string str = "world";
Dictionary dict = new Dictionary<string,object>();

dict.add( "intObj" , no  );
dict.add( "intObj" , str );


int a = (int) Storage.Get("age"); //everthing was perfect till i see cast .
string b = (string) Storage.Get("name");
double c = (double) Storage.Get("bmi");

question: how can i modify square-Brackets [] to cast type before returnig value so it will look like this;

int a = dict["intObject"] ;   //we got rid of casting forever
string b = dict["stringObject"] ;

thank you.

(Answered before the .NET 2.0 requirement was mentioned - it may still be useful for others.)

You can use a Dictionary<string, dynamic> instead - at which point the compile-time type of the expression dict["stringObject"] will be dynamic. The assignment to a variable of type string will then perform the conversion at execution time.

You can't change how Dictionary<string, object> behaves though. You would have to change the type argument... and no, you can't do this with .NET 2.0.
