problem saving date to mysql from asp.net

Question

I m trying to save the date to mysql from jquery *DatePicker* from C#

string datetime = txtDate.Text + " " + time;//05/11/2011 5:30 pm                    

string getSQL1 = 
   "INSERT into tblconcertdetail 
   (Address, City, Pincode, Country, Concert_Date) 
   VALUES ('" + addr + "','" + txtCCity.Text + "','" + txtCpincode.Text + "','" +
   ddlCCountry.SelectedItem.Text + "','" + Convert.DateTime(datetime) + "')";

Here getsql1 shows me the date field filled but in database it stores 0000-00-00 00:00 value. I m not getting why it is so.

I also try convert.ToString(datetime) to.

As mentioned in comments, you have to use parameters for 2 reasons:

1. Prevent SQL Injections.
2. Handle data type conversions. In your case, handling the .NET DateTime type to its equivalent value in database.
