Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
The ManagementQualifier attribute contains additional WMI provider-related information about an associated WMI class, instance, property, field or method.
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.

Examples
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.
[ManagementQualifier("Association", Flavor = ManagementQualifierFlavors.DisableOverride)]
public class AssociationSample
{
}
Remarks
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.

Creates an instance of the ManagementQualifierAttribute. |
Properties
| Flavor |
Flavor of the attribute. |
| Name |
Name of the qualifier. |

When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute) |
| Value |
Value associated with the qualifier. |
Methods
| Equals(Object) |
Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute) |
| GetHashCode() |
Returns the hash code for this instance. (Inherited from Attribute) |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| IsDefaultAttribute() |
When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute) |
| Match(Object) |
When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute) |
| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |

Returns a string that represents the current object. (Inherited from Object) |
Explicit Interface Implementations
| _Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr) |
Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute) |
| _Attribute.GetTypeInfo(UInt32, UInt32, IntPtr) |
Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute) |
| _Attribute.GetTypeInfoCount(UInt32) |
Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute) |
| _Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) |
Provides access to properties and methods exposed by an object. (Inherited from Attribute) |
