ManagementProbeAttribute Class

Definition

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

Note: the WMI .NET libraries are now considered in final state, and no further development, enhancements, or updates will be available for non-security related issues affecting these libraries. The MI APIs should be used for all new development.

public ref class ManagementProbeAttribute sealed : System::Management::Instrumentation::ManagementMemberAttribute
[System.AttributeUsage(System.AttributeTargets.Field | System.AttributeTargets.Property, AllowMultiple=false)]
public sealed class ManagementProbeAttribute : System.Management.Instrumentation.ManagementMemberAttribute
type ManagementProbeAttribute = class

Examples

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

[ManagementProbe]  
string count;  

The next example shows how to use the ManagementProbe attribute to mark a property.

// Use the ManagementProbe attribute to specify that a property  
// is a read-only property in the provider. Consumers will be  
// able to get this property value through WMI.  
[ManagementProbe]  
public int ReadOnlyProperty  
{  
    get { return this.propertyValue; }  
}  

Remarks

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.
