Date Conversion

Question

I have date in this format

 

string strdob =Convert.ToDateTime(ddlDay.SelectedValue + "-" + ddlMonth.SelectedValue + "-" + ddlYear.SelectedValue).ToString("yyyy-MM-dd");

 

Output is like "2017-03-06"

 

In my database i stored date as  {2017-03-06 00:00:00}

 

I used this ,,DateTime DOBDate = DateTime.Parse(strdob); 

 but the Result Shows like {06-03-2017 00:00:00}

 

I want to display it as  {2017-03-06 00:00:00}.How can i do it??
