如何使用asp.net2.0的UpdateBatchSize高效上传文件

使用UpdateBatchSize效率真的很高，我做了一个小demo，希望大家在项目中灵活的使用它，代码如下提供DEMO下载

 

protected void Button1_Click(object sender, EventArgs e)
        {
            ListBox1.Items.Clear();

            SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["demoConnectionString"].ToString());
            SqlCommand selectComm = new SqlCommand("select * from product", conn);
            SqlCommand updateComm = new SqlCommand("update product set remark=@remark", conn);
            updateComm.Parameters.Add("@remark", SqlDbType.VarChar, 200, "remark");
            updateComm.UpdatedRowSource = UpdateRowSource.None;

            SqlDataAdapter sda = new SqlDataAdapter();
            sda.SelectCommand = selectComm;
            sda.UpdateCommand = updateComm;
            DataSet ds = new DataSet();
            sda.Fill(ds);
            //for (int i = 1; i < 10; i++)
            //{
            //    UpdateData(sda, ds, i);
            //}
            UpdateData(sda, ds, 300);
        }
        public void UpdateData(SqlDataAdapter sda, DataSet ds, int recordCount)
        {
            foreach (DataRow row in ds.Tables[0].Rows)
            {
                row["remark"] = "当前时间：" + DateTime.Now.ToString();
            }
            try
            {
                sda.UpdateBatchSize = recordCount;
                long oldTicks = DateTime.Now.Ticks / TimeSpan.TicksPerMillisecond;
                sda.Update(ds);
                long ticksSpan = (DateTime.Now.Ticks / TimeSpan.TicksPerMillisecond - oldTicks) / 1000;
                ListBox1.Items.Add("UpdateBatchSize=" + recordCount.ToString() + "时，用时:" + ticksSpan.ToString() + "。");
            }
            catch (Exception ex)
            {
                ListBox1.Items.Add(ex.Message);
            }
            finally
            {

            }
        }
