ManagementProbeAttribute Class

The ManagementProbe attribute indicates that a property or field represents a read-only WMI property.

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

[AttributeUsageAttribute(AttributeTargets.Property|AttributeTargets.Field, AllowMultiple = false)]
[HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort = true)]
public sealed class ManagementProbeAttribute : ManagementMemberAttribute


The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: MayLeakOnAbort. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

The property or field must be public. The class that contains the property must be marked with the ManagementEntityAttribute attribute. Any fields or properties in the class that are not marked with this or another WMI Provider Extensions attribute will not be instrumented.

The following example shows how to use the ManagementProbe attribute to indicate that a field represents a read-only WMI property.
