MySqlCommand cmd.ExecuteReader() errors when sitting on a breakpoint for over 3 seconds

Question

I've come across a strange bug that I can't figure out. If I set a breakpoint on a MySqlCommand cmd.ExecuteReader() and sit on the breakpoint for less than 5 seconds, then continue, everything executes without any problems. But if I sit on the breakpoint for more than 5 seconds I get the error Fatal error encountered during command execution. . The MySqlCommand.CommandTimeout is set to 30, and according to MSDN , the CommandTimeout represents seconds. The connection timeout is set to 15. Why is this happening?

Breakpoint position

After waiting >= 5 seconds

您可以尝试通过添加“ Connection Timeout=0 ”在连接字符串中指定超时。
