Question

How often are you into a fromdate-todate scenario.
Or perhaps a fromValue-toValue.

How do you do those times?
I use one of those commonly,

T = ObjectType (DateTime, int, string..)

Dictionary<T,T> (used with .Single())

T fromDate;
T toDate;

T[] comparison;

Which are directly used or returned by a method.

Very Very seldom i stand create a whole object

public struct T 
{
   T fromDate { get; set;}
   T toDate { get; set;}
}

public Method T(params)
{
   ..some operations..
   return T { fromDate = someBegin, toDate = someEnd };
}

Everytime time, I want a stright and simple KeyValuePair<T,T> test;. The problem to me, using KeyValuePair, is missleading if used this way?? If I see a KeyValuePair in someones code, i look at the variable like “index 10, category books”.

What are your suggestion?

Answer 1

If you have .NET Framework 4, I’d suggest to use Tuple<T, T> instead, since it does not imply a key-value-relationship like KeyValuePair.
