IRegisterMetadata.Register 方法

發行項

更新：2007 年 11 月

會將設計階段中繼資料附加至特定控制項型別。

命名空間： Microsoft.Windows.Design.Metadata
組件： Microsoft.Windows.Design (在 Microsoft.Windows.Design.dll 中)

語法

Sub Register

Dim instance As IRegisterMetadata

instance.Register()

void Register()

void Register()

function Register()

備註

實作 Register 方法的類別都應該使用 AddAttributeTable 方法，將中繼資料加入至存放區。

範例

在下列程式碼範例中，會說明如何實作 Register 方法。Metadata 類別會將裝飾項提供者附加至控制項。如需詳細資訊，請參閱逐步解說：建立設計階段裝飾項。

' Container for any general design-time metadata to initialize.
' Designers look for a type in the design-time assembly that 
' implements IRegisterMetadata. If found, designers instantiate 
' this class and call its Register() method automatically.
Friend Class Metadata
    Implements IRegisterMetadata

    ' Called by the designer to register any design-time metadata.
    Public Sub Register() Implements IRegisterMetadata.Register
        Dim builder As New AttributeTableBuilder()

        ' Add the adorner provider to the design-time metadata.
        builder.AddCustomAttributes(GetType(ButtonWithDesignTime), _
                                    New FeatureAttribute(GetType(OpacitySliderAdornerProvider)))

        MetadataStore.AddAttributeTable(builder.CreateTable())
    End Sub

End Class

// Container for any general design-time metadata to initialize.
// Designers look for a type in the design-time assembly that 
// implements IRegisterMetadata. If found, designers instantiate 
// this class and call its Register() method automatically.
internal class Metadata : IRegisterMetadata
{
    // Called by the designer to register any design-time metadata.
    public void Register()
    {
        AttributeTableBuilder builder = new AttributeTableBuilder();

        // Add the adorner provider to the design-time metadata.
        builder.AddCustomAttributes(
            typeof(ButtonWithDesignTime), 
            new FeatureAttribute(typeof(OpacitySliderAdornerProvider)));

        MetadataStore.AddAttributeTable(builder.CreateTable());
    }
}
