Examples
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 class Baz
{
void SetColor( [ComAliasName("stdole.OLE_COLOR")]int cl );
[returnvalue:ComAliasName("stdole.OLE_COLOR")]
int GetColor();
};
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
Remarks
You can apply this attribute to parameters, fields, properties, or return values.
Constructors
ComAliasNameAttribute(String) |
Initializes a new instance of the ComAliasNameAttribute class with the alias for the attributed field or parameter. |
Properties
TypeId |
When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute) |
Value |
Gets the alias for the field or parameter as found in the type library when it was imported. |
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) |
