To provide a TRIAL period to my application when the user first runs the application I save the FirstRunTime like this:

```
string sFirstRunDate = DateTime.Today.ToShortDateString();
saveInfo.saveFirstRun(sFirstRunDate );  // saves as a string to a text file

```

Now everytime I run the application I want to see if it has been more then 60 days and if so terminate (60-day trial only). How can I do that compare?

```
string sFirstRunDate = saveInfo.getFirstRun();   // returns the string I saved earlier
DateTime dtFirstRunDate = DateTime.Parse(sFirstRunDate);  // makes it a DateTime
DateTime now = DateTime.Today.ToShortDateString();   // why am I doing this?

```

So how can I take the two dates and compare them to see if it has been more then 60 days or not?
Thanks,
