最近在學(xué)習(xí)WCF,返回datatable的時(shí)候老是出現(xiàn)“An error occurred while receiving the HTTP response to http://localhost:9999/calculatorservice. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.”的錯(cuò)誤。檢查了半天才發(fā)現(xiàn)原來(lái)是返回的datatable沒(méi)有給tablename賦值。

?

代碼 public?System.Data.DataTable?GetDataTable()
????????{
????????????DataTable?mydt?=?new?DataTable();
????????????mydt.Columns.Add("UserID",?typeof(int));
????????????mydt.Columns.Add("UserName",?typeof(string));
????????????mydt.Columns.Add("Birthday",?typeof(DateTime));
????????????for?(int?i?=?0;?i?<?300;?i++)
????????????{
????????????????DataRow?dr?=?mydt.NewRow();
????????????????dr["UserID"]?=?i?+?1;
????????????????dr["UserName"]?=?"xx"?+?i;
????????????????dr["Birthday"]?=?DateTime.Now;
????????????????mydt.Rows.Add(dr);
????????????}
????????????return?mydt;
????????}

?

?后來(lái)加上mydt.TableName="mydt";就好了。
