Any difference between DateTime.Parse and Convert.ToDateTime?

DateTime.Parse has an overload that takes only one String and nothing else and it uses the current Locale info without you having to pass it in.

DateTime.Parse will throw an Exception when a null string is passed, Convert.ToDateTime will return DateTime.MinValue on passing a null value.

Per an answer on another forum from Jon Skeet...

Convert.ToDateTime uses DateTime.Parse internally, with the current culture - unless you pass it null, in which case it returns DateTime.MinValue.

If you're not sure string is a valid DateTime, use neither and instead, use DateTime.TryParse()

If you're sure the string is a valid DateTime, and you know the format, you could also consider the DateTime.ParseExact() or DateTime.TryParseExact() methods.
