Remarks
A connection may be "broken" under many circumstances. For example, a computer running Visual Studio with an open connection that is disconnected from the network would cause the connection to fall into a broken state.
注意
The only possible interaction with a connection in the broken state is to close it.
This value cannot change on its own; rather, it is set as the result of attempting to act on the connection, such as opening it, running a command against it, or closing it.
Note, too, that a connection typically gets into the broken state only because of an attempt to interact with it. For example, a connection can remain in the Open state after you disconnect the network cable, but the next time you attempt to execute a command, it would move into the Broken state. This points out how it is not normally possible to know with certainty whether a connection is broken.
