ManagementQualifierAttribute Class

The ManagementQualifier attribute contains additional WMI provider-related information about an associated WMI class, instance, property, field or method.


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

[<AttributeUsageAttribute(AttributeTargets.All, AllowMultiple = true)>]
type ManagementQualifierAttribute =  
        inherit Attribute

The ManagementQualifierAttribute type exposes the following members.

Public methodManagementQualifierAttributeCreates an instance of the ManagementQualifierAttribute.

Public propertyFlavorFlavor of the attribute.
Public propertyNameName of the qualifier.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Public propertyValueValue associated with the qualifier.

Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

Qualifiers are name/value pairs used by the WMI infrastructure. Most of the necessary WMI qualifiers are automatically generated by the WMI.NET Provider Extensions infrastructure. Many of the other attributes cause the generation of WMI qualifiers. However, this attribute lets you manually associate additional qualifiers should you need to do so.

To learn more about this topic, see WMI Qualifiers in the WMI SDK on MSDN online.

The following example demonstrates using the ManagementQualifier attribute to indicate that a class implements a WMI association class. In this case, the qualifier has a DisableOverride flavor that specifies that the effect of the qualifier cannot be overridden in subclasses.
