ComAliasNameAttribute 類別

定義

表示參數或欄位類型的 COM 別名。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)]
public sealed class ComAliasNameAttribute : Attribute
type ComAliasNameAttribute = class
    inherit Attribute
Public NotInheritable Class ComAliasNameAttribute
Inherits Attribute

ComAliasNameAttribute
屬性

範例

在下列類型程式庫中,OLE_COLORint的別名。In the following type library, OLE_COLOR is an alias for int. 在匯入期間,Color 存取子的引數會以 ComAliasNameAttribute 標記,以指出類型程式庫將其參考為 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);  
}  
  

匯入為: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

備註

您可以將此屬性套用至參數、欄位、屬性或傳回值。You can apply this attribute to parameters, fields, properties, or return values.

建構函式

ComAliasNameAttribute(String)

使用屬性化欄位或參數的別名,初始化 ComAliasNameAttribute 類別的新執行個體。Initializes a new instance of the ComAliasNameAttribute class with the alias for the attributed field or parameter.

屬性

TypeId

在衍生類別中實作時,取得這個 Attribute 的唯一識別碼。When implemented in a derived class, gets a unique identifier for this Attribute.

(繼承來源 Attribute)
Value

取得匯入時在型別程式庫中找到的欄位或參數的別名。Gets the alias for the field or parameter as found in the type library when it was imported.

方法

Equals(Object)

傳回值,這個值指出此執行個體是否與指定的物件相等。Returns a value that indicates whether this instance is equal to a specified object.

(繼承來源 Attribute)
GetHashCode()

傳回這個執行個體的雜湊碼。Returns the hash code for this instance.

(繼承來源 Attribute)
GetType()

取得目前執行個體的 TypeGets the Type of the current instance.

(繼承來源 Object)
IsDefaultAttribute()

在衍生類別中覆寫時,表示這個執行個體的值是衍生類別的預設值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(繼承來源 Attribute)
Match(Object)

在衍生類別中覆寫時,會傳回值,表示這個執行個體是否等於指定物件。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(繼承來源 Attribute)
MemberwiseClone()

建立目前 Object 的淺層複製。Creates a shallow copy of the current Object.

(繼承來源 Object)
ToString()

傳回代表目前物件的字串。Returns a string that represents the current object.

(繼承來源 Object)

明確介面實作

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

將一組名稱對應至一組對應的分派識別項 (Dispatch Identifier)。Maps a set of names to a corresponding set of dispatch identifiers.

(繼承來源 Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

擷取物件的類型資訊,可以用來取得介面的類型資訊。Retrieves the type information for an object, which can be used to get the type information for an interface.

(繼承來源 Attribute)
_Attribute.GetTypeInfoCount(UInt32)

擷取物件提供的類型資訊介面數目 (0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1).

(繼承來源 Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

提供物件所公開的屬性和方法的存取權。Provides access to properties and methods exposed by an object.
