语法

声明
Public Shared Operator - ( _
    eventSet As ServerDdlTriggerEventSet, _
    anEvent As ServerDdlTriggerEvent _
) As ServerDdlTriggerEventSet
用法
Dim eventSet As ServerDdlTriggerEventSet
Dim anEvent As ServerDdlTriggerEvent
Dim returnValue As ServerDdlTriggerEventSet

returnValue = (eventSet - anEvent)

public static ServerDdlTriggerEventSet operator -(
    ServerDdlTriggerEventSet eventSet,
    ServerDdlTriggerEvent anEvent
)

public:
static ServerDdlTriggerEventSet^ operator -(
    ServerDdlTriggerEventSet^ eventSet, 
    ServerDdlTriggerEvent^ anEvent
)

static let inline (-)
        eventSet:ServerDdlTriggerEventSet * 
        anEvent:ServerDdlTriggerEvent  : ServerDdlTriggerEventSet
