Properties
Name | Description | |
---|---|---|
TypeId | When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.) |

Methods
Name | Description | |
---|---|---|
Equals | Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) | |
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.) | |
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
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.) |
