In C #. net, batch processing is used to process big data and database interactions, improving performance and reducing memory pressure.

Int batchmax = 100; // set int curloc = 0; arraylist personlist = NULL; // batch processing while (true) {# region batch if (curloc + batchmax> arrpersonid. count) {personlist = arrpersonid. getrange (curloc, arrpersonid. count-curloc); curloc = arrpersonid. count;} else {personlist = arrpersonid. getrange (curloc, batchmax); curloc = curloc + batchmax;} If (personlist = NULL | personlist. count = 0) {break;} # endregion // use the new data set personlist to interact with the data, reducing the pressure on a query, at the same time, it also reduces the low performance of a single loop}
