Question

Here is my following code:

string csr = "connection string";
string add = "Insert INTO table (Column1,Column2,Column3) Values (@Column1,@Column2,@Column3)";
using(SqlConnection connect = new SqlConnection(csr))
{
    using ( SqlCommand command = new SqlCommand(add,connect))
    {
        command.Parameters.AddWithValue("Column1",textbox1.text");
        //and so on
        connect.Open();
        command.ExecuteReader();
        connect.Close();
    }
}

I can see the data added in the gridview but when I check the table data in c# is empty, no value added. what’s wrong?

Answer 1

You shouldn’t have the connect.Close();, the using statement will take care of that for you.
