Connection pooling isn't the answer to this problem.连接池不是这个问题的答案。 Connection pooling allows multiple connections to be made to the server and then recycled to avoid having to reestablish the connection.连接池允许与服务器建立多个连接，然后再循环以避免必须重新建立连接。 Establishing and reestablishing connections can be very expensive in time and computing resources.建立和重新建立连接在时间和计算资源方面可能非常昂贵。

What you're looking for is to increase the command timeout.您正在寻找的是增加命令超时。 This can be done one of two ways.这可以通过以下两种方式之一来完成。 Either in the connection string by specifying default command timeout or by assigning a value to the CommandTimeout property on the MySqlCommand .通过指定默认命令超时或通过为MySqlCommand上的CommandTimeout属性分配一个值，在连接字符串中。
