Save DateTime in dd/MM/yyyy format

  //this.Text = "22/11/2009";
        string CreatedDate = DateTime.Now.ToString("dd/MM/yyyy");
        string LastUpdatedDate = DateTime.Now.ToString("dd/MM/yyyy");
        string CreatedTime = DateTime.Now.ToString("hh:mm:ss");  //txtStartTime.Text

        objUserDetail.CreateDate = CreatedDates;
        objUserDetail.LastUpdatedDate = LastUpdatedDates;
        Repository.UserProvider.Save(objUserDetail);
Use the following code for dd/MM/yyyy:
---------------------------------------
string format = "dd/MM/yyyy"; 
DateTime dt = DateTime.ParseExact(dateString, format, provider);
Use the following code for MM/dd/yyyy:
-------------------------------------
string format = "MM/dd/yyyy"; 
DateTime dt = DateTime.ParseExact(dateString, format, provider);
