C#

// dateOfBirth will simulate your text from Txt_dob.Text
string dateOfBirth = DateTime.Now.ToString("dd/MM/yyyy");

DateTime dateTimeInstance = DateTime.ParseExact(
    dateOfBirth,
    "dd/MM/yyyy",
    System.Globalization.CultureInfo.InvariantCulture);
// You now have a DateTime instance.

// If you need this as a string in MySQL format

string mySqlString = dateTimeInstance.ToString("yyyy/MM/dd");
