call stored procedure with parameter to insert entered data

[zleug]

Hi All.

On online I found information related to my question. But I cannot understand what is dc in that line:

using (SqlConnection con = new SqlConnection(dc.Con)) {

Does that insert data to the table according specified stored procedure? Is that correct?

private void button1_Click(object sender, EventArgs e) {
using (SqlConnection con = new SqlConnection(dc.Con)) {
using (SqlCommand cmd = new SqlCommand("sp_Add_contact", con)) {
cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.Add("@FirstName", SqlDbType.VarChar).Value = txtFirstName.Text;
cmd.Parameters.Add("@LastName", SqlDbType.VarChar).Value = txtLastName.Text;

con.Open();
cmd.ExecuteNonQuery();
}
}
}


Thanks.
