ManagementEnumeratorAttribute Class
The ManagementEnumerator attribute marks a method that returns all the instances of a WMI class.
System.Attribute
System.Management.Instrumentation.ManagementMemberAttribute
System.Management.Instrumentation.ManagementNewInstanceAttribute
System.Management.Instrumentation.ManagementEnumeratorAttribute
Assembly: System.Core (in System.Core.dll)
The ManagementEnumeratorAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
 | ManagementEnumeratorAttribute | Initializes a new instance of the ManagementEnumeratorAttribute class. |
| Name | Description | |
|---|---|---|
| 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.) |
| Name | Description | |
|---|---|---|
| Equals | Infrastructure. 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 | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
| _Attribute.GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
| _Attribute.GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
| _Attribute.GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
| _Attribute.Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
The method must be static and public. It must return a collection of all instances of the WMI class. The collection can be of any type convertible to IEnumerable.
| Note |

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 Enumerator attribute to mark a method that is used to enumerate instances of a class. In this case, the Enumerate method uses the Process class to retrieve all of the processes running on the computer.
[C#]
[ManagementEnumerator]
public static IEnumerable Enumerate()
{
Process[] rgProcesses = Process.GetProcesses();
for (int i = 0; i < rgProcesses.Length; i++)
{
yield return new ProcessProvider(rgProcesses[i]);
}
}
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
