Basically the Convert class makes it easier to convert between all the base types.
The Convert.ToInt32(String, IFormatProvider) underneath calls the Int32.Parse. So the only difference is that if a null string is passed to Convert it returns 0, whereas Int32.Parse throws an ArgumentNullException.
It is really a matter of choice whichever you use.
Also have a look at the new .NET 2.0 method Int32.TryParse, which attempts to convert a string to an int without throwing an exception.
