ManagementQualifierAttribute 类

定义

ManagementQualifier 属性包含有关关联的 WMI 类、实例、属性、字段或方法的与 WMI 提供程序相关的信息。The ManagementQualifier attribute contains additional WMI provider-related information about an associated WMI class, instance, property, field or method.

注意:WMI .NET 库现在视为处于最终状态,且没有可用于会影响这些库的非安全性相关问题的进一步开发、增强或更新。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. MI API 应用于所有新的开发。The MI APIs should be used for all new development.

public ref class ManagementQualifierAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.All, AllowMultiple=true)]
public sealed class ManagementQualifierAttribute : Attribute
type ManagementQualifierAttribute = class
    inherit Attribute
Public NotInheritable Class ManagementQualifierAttribute
Inherits Attribute

示例

下面的示例演示如何使用 ManagementQualifier 特性指示类实现 WMI 关联类。The following example demonstrates using the ManagementQualifier attribute to indicate that a class implements a WMI association class. 在这种情况下, 限定符有DisableOverride一个风格, 指定不能在子类中覆盖限定符的效果。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  
{  
}  

注解

限定符是 WMI 基础结构使用的名称/值对。Qualifiers are name/value pairs used by the WMI infrastructure. 大多数必需的 WMI 限定符都是由 WMI.NET 提供程序扩展基础结构自动生成的。Most of the necessary WMI qualifiers are automatically generated by the WMI.NET Provider Extensions infrastructure. 许多其他属性会导致生成 WMI 限定符。Many of the other attributes cause the generation of WMI qualifiers. 但是, 此属性允许您手动关联其他限定符。However, this attribute lets you manually associate additional qualifiers should you need to do so.
