Question

i have used a checkbox list in my project .am storing all the checked items values in arraylist using code below

 ArrayList  services= new ArrayList();
for (int i = 0; i < chkservices.Items.Count; i++)
        {
            if (chkservices.Items[i].Selected == true)
            {
                services.Add(chkservices.Items[i].Text+',');
            }
        }

now the problem is when i insert data in to database instead of data in the arraylist it gets inserted as ‘System.Collections.ArrayList‘ how can i insert all values into database in a single insert statement?

EDIT

inserting into database

con.Open();
        SqlCommand cmd = new SqlCommand("insert into XXX(First_Name,Last_Name,ServicesProvided) values ('" + txtfrstname.Text + "','" + txtlastname.Text + "','" + services + "')", con);
        cmd.ExecuteNonQuery();
        con.Close();

or could anyone provide me a alternative for arraylist..i need to save checked items from checkboxlist and save it in database

it should be saved in database as

  First_Name             Last_name                 ServicesProvided
user1firstname        user1lastname               selectedvalue1,
                                              selectedvalue2,selectedvalue3

Answer 1

Why not to concatenate your data using the following code:

 var mydata = String.Join(',', chkservices.Items
   .Where( a => a.Selected).Select( b => b.Text));

So you can add your data as a string.

EDIT:
It is a very bad habit of concatenating strings to make a query! Apart from many side effects like in your case here it is a great security breach. Try the parameterized query instead:

     SqlCommand cmd = new SqlCommand(
         @"insert into XXX(First_Name,Last_Name,ServicesProvided) values 
         (@First_Name,@Last_Name,@ServicesProvided")", con); 
      cmd.Parameters.AddWithValue("@ServicesProvided", mydata);
      cmd.Parameters.AddWithValue("@First_Name", frstname.Text);
      cmd.Parameters.AddWithValue("@Last_Name", txtlastname.Text);
    cmd.ExecuteNonQuery();

mydata is the variable from my first example.
