Linq to SQL插入存储过程从插入中排除第一行

Question

I have a stored procedure in SQL Server responsible for inserting records into the database:

ALTER proc [dbo].[Sp_Add_Item_Decription]
    @orderid int,
    @itemid int,
    @qty decimal(18, 2),
    @price decimal(18, 2)
as
    insert into [ResturantDB].[dbo].[ItemDescribtion] ([OrderID], [ItemID],[Qty], [Price])
    values (@orderid, @itemid, @qty, @price)

I used Linq to SQL to generate the below code but when I execute this code, if the datagridview contains one row it isn't inserted into the database, but if the datagridview contains more than one record then all records are inserted except the first row. I don't know what is the problem. I need to insert all the datagridview records.

private void Button3_Click(object sender, EventArgs e)
{
    dataGridView1.DataSource = DTL;

    if (!string.IsNullOrEmpty(textBox1.Text) && !string.IsNullOrEmpty(textBox3.Text))
    {
        for(int i = 0; i < dataGridView1.Rows.Count - 1; i++)
        {
            resturantDataContext addorderdes = new resturantDataContext();
            addorderdes.Sp_Add_Item_Decription(Convert.ToInt32(textBox1.Text),
                               Convert.ToInt32(dataGridView1.Rows[i].Cells[0].Value),
                               Convert.ToDecimal(dataGridView1.Rows[i].Cells[3].Value),
                               Convert.ToDecimal(dataGridView1.Rows[i].Cells[4].Value));
            addorderdes.SubmitChanges();
        }

        RadMessageBox.Show("RECORD ADDED!");
    }
}

Answer 1

Instead of

for(int i = 0; i < dataGridView1.Rows.Count - 1; i++)
        {

use

for(int i = 0; i < dataGridView1.Rows.Count; i++)
        {

In this way you get the last row too.

Answer 2

Your loop termination is on:

i < dataGridView1.Rows.Count - 1;

This will always be one less than the number of rows in the data grid.

Just replace it with:

i < dataGridView1.Rows.Count;

Also as Adrian Iftode points out in his comment you don't need to recreate the context on every iteration of the loop and you don't need to call SubmitChanges as your stored procedure is writing the data directly back to the database.
