Retrieve files from a folders for the specified datetime ran

Question

I am able to retrieve all the files from the specified folder using following line.

string[] filePaths = Directory.GetFiles(@"c:\MyDir\");

On UI I will have 2 parameters --

Startdate and Starttime

EndDate and Endtime

I want to retrieve only those files where Date Modified of files (in the windows explorer) is in between startdatetime and enddatetime

Any clue?
