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

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 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.
[ManagementBind]
public ClassConstructor(int Id)
{
     // Set this class instance to a specific instance
     // by assigning property values and
     // giving unique values to the key properties.
}

Remarks

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.

Constructors

ManagementBindAttribute()

Initializes a new instance of the ManagementBindAttribute class. This is the parameterless constructor.

Properties

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

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)
ToString()	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)
