DefaultBindingPropertyAttribute 類別

定義

指定元件的預設繫結屬性。Specifies the default binding property for a component. 這個類別無法被繼承。This class cannot be inherited.

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

範例

下列程式碼範例將示範如何DefaultBindingPropertyAttribute使用類別來指定資料系結的預設屬性。The following code example demonstrates using the DefaultBindingPropertyAttribute class to specify the default property for data binding. 如需完整的程式代碼清單, 請參閱如何:在 Windows Forms 控制項中套用屬性。For a full code listing, see How to: Apply Attributes in Windows Forms Controls.

// This control demonstrates a simple logging capability. 
[ComplexBindingProperties("DataSource", "DataMember")]
[DefaultBindingProperty("TitleText")]
[DefaultEvent("ThresholdExceeded")]
[DefaultProperty("Threshold")]
[HelpKeywordAttribute(typeof(UserControl))]
[ToolboxItem("System.Windows.Forms.Design.AutoSizeToolboxItem,System.Design")]
public class AttributesDemoControl : UserControl
{
' This control demonstrates a simple logging capability. 
<ComplexBindingProperties("DataSource", "DataMember"), _
DefaultBindingProperty("TitleText"), _
DefaultEvent("ThresholdExceeded"), _
DefaultProperty("Threshold"), _
HelpKeywordAttribute(GetType(UserControl)), _
ToolboxItem("System.Windows.Forms.Design.AutoSizeToolboxItem,System.Design")> _
Public Class AttributesDemoControl
    Inherits UserControl

備註

DefaultBindingPropertyAttribute是在類別層級指定。The DefaultBindingPropertyAttribute is specified at the class level. 它可以被繼承, 而且不允許在相同類別上有多個屬性。It can be inherited and does not allow multiple attributes on the same class.

如需使用屬性的詳細資訊, 請參閱屬性For more information about using attributes, see Attributes.

建構函式

DefaultBindingPropertyAttribute()

不使用參數來初始化 DefaultBindingPropertyAttribute 類別的新執行個體。Initializes a new instance of the DefaultBindingPropertyAttribute class using no parameters.

DefaultBindingPropertyAttribute(String)

使用指定的屬性名稱,初始化 DefaultBindingPropertyAttribute 類別的新執行個體。Initializes a new instance of the DefaultBindingPropertyAttribute class using the specified property name.

欄位

Default

表示 DefaultBindingPropertyAttribute 類別的預設值。Represents the default value for the DefaultBindingPropertyAttribute class.

屬性

Name

取得 DefaultBindingPropertyAttribute 所繫結之元件的預設繫結屬性名稱。Gets the name of the default binding property for the component to which the DefaultBindingPropertyAttribute is bound.

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)

判斷指定的 Object 和目前的 DefaultBindingPropertyAttribute 執行個體是否相等。Determines whether the specified Object is equal to the current DefaultBindingPropertyAttribute instance.

GetHashCode()

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

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.
