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 ref class ManagementBindAttribute sealed : public ManagementNewInstanceAttribute

The ManagementBindAttribute type exposes the following members.

Public methodManagementBindAttributeInitializes a new instance of the ManagementBindAttribute class. This is the default constructor.

Public propertyNameGets or sets the name of the management attribute. (Inherited from ManagementMemberAttribute.)
Public propertySchemaGets or sets a value that defines the type of output that the method that is marked with the ManagementEnumerator attribute will output.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

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.)

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 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.

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.
