ManagementBindAttribute Class

The ManagementBind attribute indicates that a method is used to return the instance of a WMI class associated with a specific key value.

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

[AttributeUsageAttribute(AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple = false)]
[HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort = true)]
public sealed class ManagementBindAttribute : ManagementNewInstanceAttribute


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.

This attribute marks the method that the infrastructure uses to perform the WMI get operation. The method must take the key values of the corresponding WMI class as parameters and return the associated instance of the WMI class.

Important   The method parameters must have exactly the same name and type as the key parameters of the class. The key parameters are identified by the .ManagementKeyAttribute attribute

The method must assign values to all instrumented properties of the class.

When the WMI Provider Extensions infrastructure requires this binding functionality, it first searches for a constructor with this attribute. If none is found, it then searches for a static method that returns the WMI class type.

The target of this attribute must be either a method or a static method.

The following example shows how to use the ManagementBind attribute to mark the constructor of a class.


// Use the ManagementBind attribute to specify that this constructor
// is used to attach a class instance to a specific WMI
// instance. The constructor should set the values of the
// key properties of the WMI instance.
public ClassConstructor(int Id)
     // Set this class instance to a specific instance
     // by assigning property values and 
     // giving unique values to the key properties. 

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
