方法详细信息

getCount

public int getCount()
             throws WMIException

Get how many items are in this SWbemObjectSet collection. This property is read-only.

One thing to be careful of when using Count is that WMI does not keep a running tally of the number of items in a collection. If you request Count for a collection, WMI cannot instantly respond with a number; instead, it must literally count the items, enumerating the entire collection. For a collection that has relatively few items, such as services, this enumeration likely takes less than a second. Counting the number of events in an event log collection, however, can take considerably longer.

And then suppose you want to display the property values for every event in the collection. If so, WMI will have to enumerate the entire collection a second time.

Note: If you attempt to get this property from an SWbemObjectSet object that is returned from a method where the specified flags are included the wbemFlagForwardOnly flag, you will get an wbemErrFailed error.

返回：

The count of items in this SWbemObjectSet collection.

抛出：

WMIException
