SqlBulkCopy类 基本使用方法

 private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                string DatabaseOne = "Data Source = DATABASE-VPC\\SQL2005; User ID = sa; password = admin; Initial Catalog = AdventureWorks; Pooling=true";
                string DatabaseTwo = "Data Source = DATABASE-VPC\\SQL2005; User ID = sa; password = admin; Initial Catalog = Jiang; Pooling=true";
                SqlConnection Conn = new SqlConnection(DatabaseOne);
                SqlCommand cmd = new SqlCommand();
                cmd.Connection = Conn;
                cmd.CommandType = CommandType.Text;
                cmd.CommandText = "select * from TableCopyTest";
                Conn.Open();
                DataSet ds = new DataSet();
                SqlDataAdapter per = new SqlDataAdapter(cmd);
                per.Fill(ds, "One");
                cmd.ExecuteNonQuery();
                SqlBulkCopy copytable = new SqlBulkCopy(DatabaseTwo, SqlBulkCopyOptions.UseInternalTransaction);
                copytable.BulkCopyTimeout = 500000;
                copytable.SqlRowsCopied += new SqlRowsCopiedEventHandler(copytable_SqlRowsCopied);
                copytable.NotifyAfter = ds.Tables[0].Rows.Count;

                copytable.DestinationTableName = "TableCopyTwo";
                copytable.ColumnMappings.Add("uid", "pass");///互换对应列
                copytable.WriteToServer(ds.Tables[0]);
            }
            catch (Exception ex) { MessageBox.Show(ex.Message); }
        }

        void copytable_SqlRowsCopied(object sender, SqlRowsCopiedEventArgs e)
        {
            this.label1.Text = "完成！ 共：" + e.RowsCopied.ToString();
        }
