定义

指示参数或字段类型的 COM 别名。Indicates the COM alias for a parameter or field type.

public ref class ComAliasNameAttribute sealed : Attribute

[System.Runtime.InteropServices.ComVisible(true)]
[System.AttributeUsage(System.AttributeTargets.Field | System.AttributeTargets.Parameter | System.AttributeTargets.Property | System.AttributeTargets.ReturnValue, Inherited=false)]

示例

在下面的类型库中,OLE_COLOR是其别名intIn the following type library, OLE_COLOR is an alias for int. 在导入的参数期间Color访问器标记有ComAliasNameAttribute以指示该类型库是指其作为OLE_COLORDuring 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);  
}  

作为导入: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
