这是我的代码，如果每行数据不正确，那么所有行都会回滚我的代码问题是当第一行好了它插入数据库但接下来不能和回滚无法正常工作

DateTime da = new DateTime();
da = DateTime.Now;
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
    using (DsourceDataContext dc = new DsourceDataContext())
    {
        using (TransactionScope tscope = new TransactionScope())
        {
            custompacking1 category = new custompacking1();
            {
                Double val3 = Convert.ToDouble(dataGridView1.Rows[i].Cells["fro"].Value);
                //Double val4 = Convert.ToDouble(dataGridView1.Rows[i].Cells["too"].Value.ToString());
                Double val5 = Convert.ToDouble(dataGridView1.Rows[i].Cells["gwt"].Value.ToString());
                Double val6 = Convert.ToDouble(dataGridView1.Rows[i].Cells["nwt"].Value.ToString());

                category.cid = Convert.ToInt32(dataGridView1.Rows[i].Cells["cid"].Value);
                category.tid = Convert.ToInt32(dataGridView1.Rows[i].Cells["tid"].Value);
                if (dataGridView1.Rows[i].Cells["fro"].Value != null)
                {
                    category.fro = Convert.ToDouble(dataGridView1.Rows[i].Cells["fro"].Value);
                }
                else
                {
                    category.fro = 0;
                }
                if (dataGridView1.Rows[i].Cells["too"].Value != null)
                {
                    category.too = dataGridView1.Rows[i].Cells["too"].Value.ToString();
                }
                else
                {
                    category.too = "";
                }
                if (dataGridView1.Rows[i].Cells["gwt"].Value != null)
                {
                    category.grosswt = Convert.ToDouble(dataGridView1.Rows[i].Cells["gwt"].Value);
                }
                else
                {
                    category.grosswt = 0;
                }
                if (dataGridView1.Rows[i].Cells["nwt"].Value != null)
                {
                    category.netwt = Convert.ToDouble(dataGridView1.Rows[i].Cells["nwt"].Value);
                }
                else
                {
                    category.netwt = 0;
                }
                category.date2 = dateTimePicker1.Value.ToString("MM/dd/yyyy");
                category.date1 = da.ToString("MM/dd/yyyy");
                category.gsmpcs = dataGridView1.Rows[i].Cells["gpcs"].Value.ToString();
            }

            dc.custompacking1s.InsertOnSubmit(category);
            dc.SubmitChanges();
            //dc.Dispose();
            tscope.Complete();
        }
    }
}
MessageBox.Show("Inserted");

m也可以在本论坛的帮助下使用Transactionscope，但它不能工作

当然它不会回滚，因为，当插入到DB中时，如果所有值都不正确，则会发生回滚，但即使一行是正确的，该值也会输入到DB中，在这种情况下，你会必须在代码中手动执行回滚。使用＆＃39; if＆＃39;检查datarow1.fill()的语句为true，如果返回false，则使用delete选项删除最近受影响的行
