Date comparison - How to check if 20 minutes have passed?

Question

How to check if 20 minutes have passed from current date?

For example:

var start = DateTime.Now;
var oldDate = \"08/10/2011 23:50:31\"; 

    if(start ?         


        

Answer 1

Parse oldDate into a DateTime object (DateTime.Parse).

Subtract the parsed date from start. This will return a TimeSpan.

Inspect TotalMinutes.
