Gets or sets properties in the event to be used for grouping events of the same type.
public:
property System::Collections::Specialized::StringCollection ^ GroupByPropertyList { System::Collections::Specialized::StringCollection ^ get(); void set(System::Collections::Specialized::StringCollection ^ value); };
public System.Collections.Specialized.StringCollection GroupByPropertyList { get; set; }
member this.GroupByPropertyList : System.Collections.Specialized.StringCollection with get, set
Public Property GroupByPropertyList As StringCollection
Returns a StringCollection containing the properties in the event to be used for grouping events of the same type.
The following example initializes a new WqlEventQuery and displays the event query string.
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"

End Function 'Main
End Class
Setting this property value overrides any previous value stored in the object. The query string is rebuilt to reflect the new grouping.
Null, if no grouping is required; otherwise, a collection of event property names.
