System_CAPS_pubmethod ComAliasNameAttribute

Initializes a new instance of the ComAliasNameAttribute class with the alias for the attributed field or parameter.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


Gets the alias for the field or parameter as found in the type library when it was imported.

System_CAPS_pubmethod Equals

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod GetHashCode

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod 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.)

System_CAPS_pubmethod Match

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod ToString

Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

You can apply this attribute to parameters, fields, properties, or return values.

In the following type library, OLE_COLOR is an alias for int. During import, the arguments of the Color accessor are marked with the ComAliasNameAttribute to indicate that type library refers to them as OLE_COLOR.

typedef int OLE_COLOR;  

interface Baz {
 HRESULT SetColor([in] OLE_COLOR cl);
 HRESULT GetColor([out, retval] OLE_COLOR *cl);

is imported as:

interface Baz {
 void SetColor([ComAliasName("stdole.OLE_COLOR")] int cl);
 [return: ComAliasName("stdole.OLE_COLOR")] int GetColor();
Interface Baz
    Sub SetColor( <ComAliasName("stdole.OLE_COLOR")> cl As Integer)
    Function GetColor() As <ComAliasName("stdole.OLE_COLOR")> Integer
End Interface
interface class Baz
   void SetColor( [ComAliasName("stdole.OLE_COLOR")]int cl );

   int GetColor();
