Is there a way using DateTime.Parse to validate a date in the following format?
mm/dd/yyyy

You are using an out of date browser. It may not display this or other websites correctly.
You should upgrade or use an alternative browser.

Sure - give the format to DateTime.Parse or DateTime.ParseExact. Note
that in custom format strings, "m" is for minute - "M" is for month.

If it is valid it will not throw an exception, otherwise it will. Example:
try
{
DateTime a = DateTime.Parse("01/10/200a");
MessageBox.Show("Date is good!");
}
catch (Exception ex)
{
MessageBox.Show("Date is not in proper format.");
}
This will throw an exception and display a message box. Other way is to
use a regular expression.
try
{
DateTime a = DateTime.Parse("01/10/200a");
MessageBox.Show("Date is good!");
}
catch (Exception ex)
{
MessageBox.Show("Date is not in proper format.");
}
This will throw an exception and display a message box. Other way is to
use a regular expression.

try
just a note: a specific Exception should be caught always when possible
As commonly said "Imagine an OutOfMemoryException would be thrown"...

So true, but hopefully that gives you a basic idea dwight.
