WqlEventQuery.Condition Property

Gets or sets the condition to be applied to events of the specified class.

Namespace:  System.Management
Assembly:  System.Management (in System.Management.dll)

public string Condition { get; set; }

Property Value

Type: System.String
Returns a String value containing the condition or conditions in the event query.

Setting this property value overrides any previous value stored in the object. The query string is rebuilt to reflect the new condition.

Property Value

The condition is represented as a string, containing one or more clauses of the form: <propName> <operator> <value> combined with logical operators. <propName> must represent a property defined on the event class specified in this query.

.NET Framework Security

Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.

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;
    }
}
