Assembly:  mscorlib (in mscorlib.dll)


[AttributeUsageAttribute(AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Parameter | AttributeTargets.ReturnValue, 
	Inherited = false)]
public sealed class ComAliasNameAttribute : Attribute


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.


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.)


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


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


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


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


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

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

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

System_CAPS_pubinterfaceSystem_CAPS_privmethod_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.)


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

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

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();
