ComplexBindingPropertiesAttribute 類別

定義

指定支援複雜資料繫結之元件的資料來源和資料成員屬性。Specifies the data source and data member properties for a component that supports complex data binding. 這個類別無法被繼承。This class cannot be inherited.

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

範例

下列程式碼範例將示範ComplexBindingPropertiesAttribute如何使用來識別控制項DataSourceDataMember和屬性, 以進行資料系結。The following code example demonstrates using ComplexBindingPropertiesAttribute to identify a control's DataSource and DataMember properties 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

是用來指定用於複雜資料系結的屬性, 例如以為System.Collections.IList基礎的系結。 ComplexBindingPropertiesAttributeThe ComplexBindingPropertiesAttribute is used to specify the properties used with complex data binding, such as binding based on System.Collections.IList.

ComplexBindingPropertiesAttribute屬性是在類別層級指定。The ComplexBindingPropertiesAttribute attribute is specified at the class level. 它是可繼承的, 而且不允許在相同類別上有多個屬性。It is inheritable and does not allow multiple attributes on the same class.

控制項可以同時支援簡單系結, 以及DefaultBindingPropertyAttribute和複雜的系結。A control can support both simple binding, with DefaultBindingPropertyAttribute, as well as complex binding.

欄位

Default

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

屬性

DataMember

取得 ComplexBindingPropertiesAttribute 所繫結之元件的資料成員屬性名稱。Gets the name of the data member property for the component to which the ComplexBindingPropertiesAttribute is bound.

DataSource

取得 ComplexBindingPropertiesAttribute 所繫結之元件的資料來源屬性名稱。Gets the name of the data source property for the component to which the ComplexBindingPropertiesAttribute 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 ComplexBindingPropertiesAttribute 執行個體是否相等。Determines whether the specified Object is equal to the current ComplexBindingPropertiesAttribute 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)
