Question

在几个不相关的项目中，我们在Azure上使用SqlBulkCopy到SQL数据库时遇到了异常。

还有其他人遇到过这种行为吗？我怀疑最近Azure SQL已经发生了一些变化，这破坏了这个BulkCopy。

我们遇到的错误就是这个：

[Win32Exception (0x80004005): An existing connection was forcibly closed by the remote host]

[SqlException (0x80131904): A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)]
