c# datastructure to index value with DateTime
<p>I need to store data such that a <code>DateTime</code> value and a <code>float</code> value are stored together. A <code>Dictionary</code> is not useful because when retrieving data, I don't have the exact <code>DateTime</code> value. I just give the date(not the hour,min,second values) and have to get the <code>float</code> value/values corresponding to the date. What other datastructure can I use?</p>
