WqlEventQuery.GroupWithinInterval 屬性

public:
 property TimeSpan GroupWithinInterval { TimeSpan get(); void set(TimeSpan value); };

public TimeSpan GroupWithinInterval { get; set; }

member this.GroupWithinInterval : TimeSpan with get, set

Public Property GroupWithinInterval As TimeSpan

屬性值

回傳 TimeSpan 一個包含用於分組同類型事件的區間的值。

範例

以下範例初始化一個新事件 WqlEventQuery 並顯示事件查詢字串。

using System;
using System.Management;

public class EventSample
{
    public static void Main(string[] args)
    {
        WqlEventQuery query = new WqlEventQuery();
        query.EventClassName = "__InstanceCreationEvent";
        query.Condition = "TargetInstance ISA 'Win32_NTLogEvent'";
        query.GroupWithinInterval = new TimeSpan(0, 0, 10);
        System.Collections.Specialized.StringCollection collection =
            new System.Collections.Specialized.StringCollection();
        collection.Add("TargetInstance.SourceName");
        query.GroupByPropertyList = collection;
        query.HavingCondition = "NumberOfEvents > 25";

        Console.WriteLine(query.QueryString);
        return;
    }
}

Imports System.Management


Public Class EventSample
    Public Overloads Shared Function _
        Main(ByVal args() As String) As Integer

        Dim query As New WqlEventQuery
        query.EventClassName = "__InstanceCreationEvent"
        query.Condition = "TargetInstance ISA 'Win32_NTLogEvent'"
        query.GroupWithinInterval = New TimeSpan(0, 0, 10)
        Dim collection As New System.Collections.Specialized. _
            StringCollection
        collection.Add("TargetInstance.SourceName")
        query.GroupByPropertyList = collection
        query.HavingCondition = "NumberOfEvents > 25"

        MessageBox.Show(query.QueryString)

    End Function 'Main
End Class

備註

設定此屬性值會覆蓋物件中先前儲存的任何值。 查詢字串會被重建以反映新的區間。

屬性值

若不涉及分組，則為零;否則，WMI 應在相同類型事件分組的區間。
