public SqlDependency(
	SqlCommand command
)

Parameters

The SqlCommand object to associate with this SqlDependency object. The constructor will set up a SqlNotificationRequest object and bind it to the command.

ExceptionCondition
ArgumentNullException

The command parameter is NULL.

InvalidOperationException
