You are specifying MM when you only have a single digit. Either use just a single M, or pad left with zero using the PadLeft function.

The following code demonstrates this with both dd and MM padded as desired

string format = "dd/MM/yyyy";
string mydate = "12/4/2012";
DateTime t = DateTime.ParseExact(mydate.Split('/')[0].PadLeft(2,'0') + "/" + 
                                 mydate.Split('/')[1].PadLeft(2,'0') + "/" + 
                                mydate.Split('/')[2], format, CultureInfo.InvariantCulture);

Output is:

12/04/2012 00:00:00
