ValidationPropertyAttribute 類別

定義

定義 ASP.NET 伺服器控制項用來識別驗證屬性 (Property) 的中繼資料 (Metadata) 屬性 (Attribute)。Defines the metadata attribute that ASP.NET server controls use to identify a validation property. 此類別無法獲得繼承。This class cannot be inherited.

public ref class ValidationPropertyAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Class)]
public sealed class ValidationPropertyAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Class)>]
type ValidationPropertyAttribute = class
    inherit Attribute
Public NotInheritable Class ValidationPropertyAttribute
Inherits Attribute

範例

下列程式碼範例將示範如何 ValidationPropertyAttribute 在建立自訂控制項時使用類別。The following code example demonstrates using the ValidationPropertyAttribute class when creating a custom control.

[ValidationPropertyAttribute("Message")]
public class MessageControl : Label
{
   private int _message = 0;
   public int Message
   {
      get 
      {
         return _message;
      }
      set
      {
         _message = value;
      }
   }
}
<ValidationPropertyAttribute("Message")> Public Class MessageControl
   Inherits Label
   Private _message As Integer = 0

   Public Property Message() As Integer
      Get
         Return _message
      End Get
      Set(ByVal Value As Integer)
         _message = Value
      End Set
   End Property
End Class 

備註

這個屬性通常用於以表單為基礎的輸入控制項。This attribute is typically used for form-based input controls.

建構函式

ValidationPropertyAttribute(String)

初始化 ValidationPropertyAttribute 類別的新執行個體。Initializes a new instance of the ValidationPropertyAttribute class.

屬性

Name

取得 ASP.NET 伺服器控制項的驗證屬性之名稱。Gets the name of the ASP.NET server control's validation property.

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)

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.

(繼承來源 Attribute)
