方法一:
DataTable table = new DataTable(); //TODO: init table... string connStr = "user id=" + dbInfo.UserName + ";data source=" + dbInfo.DBServerIP + ";persist security info=False;initial catalog=" + dbInfo.DatabaseName + ";password=" + dbInfo.Password; SqlConnection conn = new SqlConnection(connStr); conn.Open(); SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(conn); sqlBulkCopy.DestinationTableName = dbInfo.TableName; sqlBulkCopy.WriteToServer(table); sqlBulkCopy.Close();
方法二:
DataTable table = new DataTable(); //TODO: init table... string connStr = "user id=" + dbInfo.UserName + ";data source=" + dbInfo.DBServerIP + ";persist security info=False;initial catalog=" + dbInfo.DatabaseName + ";password=" + dbInfo.Password; DataTable dt = new DataTable(); SqlConnection conn = new SqlConnection(connStr); SqlCommand cmd = new SqlCommand(string.Format("select * from {0} where 1=2", dbInfo.TableName), conn); SqlDataAdapter sda = new SqlDataAdapter(cmd); SqlCommandBuilder Builder = new SqlCommandBuilder(sda); sda.Fill(dt); DataRow addRow = null; foreach (DataRow row in table.Rows) { addRow = dt.NewRow(); for (int i = 0; i < table.Columns.Count; i++) { addRow[i] = row[i]; } dt.Rows.Add(addRow); } sda.Update(dt);
总结
1. 只有 Insert ? 那么用 SqlBulkCopy.
2. Insert/Update/Delete ? 那么用 DataAdapter.Update.
