Question

执行SQL查询时，我会以随机间隔收到以下错误

Message: System.Data.SqlClient.SqlException (0x80131904): A transport-level error has     occurred when receiving results from the server. (provider: TCP Provider, error: 0     - The specified network name is no longer available.)

at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe)

我认为这可能是由于网络连接中断，这是正确的吗？我该如何编码？

我认为这可能是由于网络连接断开，这是正确的吗？

是的，“传输级错误”是“网络”的“极客谈话”字样。例如，当网络连接变得陈旧时，也可能发生这种情况，因为在获得连接并长时间保持连接后，服务器会重新启动。

我如何围绕此进行编码？

不幸的是，关于网络连接，你无能为力。您可以使用try / catch，查找SQL异常，然后重试计数，但最终会向最终用户报告。
