Store Array Data to Database

Question

I'm trying to store data from some arrays into the database but only the last index of the arrays were stored. I know I need to fix the looping part but I've no idea how to. Below is the code.

for (int i = 0; i < 5; i++)
        {
            cmd.Parameters["Mon1"].Value = newTA.MonAry[i];
            cmd.Parameters["Tue1"].Value = newTA.TueAry[i];
            cmd.Parameters["Wed1"].Value = newTA.WedAry[i];
            cmd.Parameters["Thu1"].Value = newTA.ThuAry[i];
            cmd.Parameters["Fri1"].Value = newTA.FriAry[i];
        }

Answer 1

You need to create and execute the command inside the loop:

for (int i = 0; i < 5; i++)
{
    using (var conn = new SqlConnection("Some Connection String"))
    using (var cmd = conn.CreateCommand())
    {
        conn.Open();
        cmd.CommandText = "INSERT INTO foo (...) VALUES (...)";
        cmd.Parameters["Mon1"].Value = newTA.MonAry[i];
        cmd.Parameters["Tue1"].Value = newTA.TueAry[i];
        cmd.Parameters["Wed1"].Value = newTA.WedAry[i];
        cmd.Parameters["Thu1"].Value = newTA.ThuAry[i];
        cmd.Parameters["Fri1"].Value = newTA.FriAry[i];
        cmd.ExecuteNonQuery();
    }
}

如果您使用的是sqlserver，则可以将此作为表类型参数传递，以便可以插入多个行， 请参见此链接
