表示需要用來處理 FeatureProvider 之 FeatureConnector<TFeatureProviderType> 的型別。

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

語法

<AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple := True)> _
Public NotInheritable Class FeatureConnectorAttribute _
    Inherits Attribute

Dim instance As FeatureConnectorAttribute

[AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple = true)]
public sealed class FeatureConnectorAttribute : Attribute

[AttributeUsageAttribute(AttributeTargets::Class, AllowMultiple = true)]
public ref class FeatureConnectorAttribute sealed : public Attribute

public final class FeatureConnectorAttribute extends Attribute

備註

您可以將 FeatureConnectorAttribute 套用至自訂 FeatureProvider 類別，以指定會發行 FeatureProvider 所需之服務的 FeatureConnector<TFeatureProviderType>。

範例

在下列程式碼範例中，會說明如何使用 FeatureConnectorAttribute，讓 FeatureConnector<TFeatureProviderType> 類別與名為 DiagnosticsMenuProvider 的功能提供者產生關聯。如需完整的程式碼清單，請參閱 HOW TO：建立自訂功能連接器。

' The DiagnosticsMenuProvider class adds a context menu item
' that displays a dialog box listing the currently running and 
' pending feature connectors. 
<FeatureConnector(GetType(DiagnosticsFeatureConnector))>  _
Public Class DiagnosticsMenuProvider
    Inherits PrimarySelectionContextMenuProvider

    Public Sub New() 
        Dim action As New MenuAction("Feature Diagnostics...")

        AddHandler action.Execute, AddressOf action_Execute 

        Items.Add(action)    
    End Sub

    Sub action_Execute(ByVal sender As Object, ByVal e As MenuActionEventArgs) 
        Dim service As IDiagnosticsService = e.Context.Services.GetRequiredService(Of IDiagnosticsService)()

        service.ShowWindow()

    End Sub

End Class

// The DiagnosticsMenuProvider class adds a context menu item
// that displays a dialog box listing the currently running and 
// pending feature connectors. 
[FeatureConnector(typeof(DiagnosticsFeatureConnector))]
public class DiagnosticsMenuProvider : PrimarySelectionContextMenuProvider 
{
    public DiagnosticsMenuProvider() 
    {
        MenuAction action = new MenuAction("Feature Diagnostics...");

        action.Execute += new EventHandler<MenuActionEventArgs>(action_Execute); 

        Items.Add(action);
    }

    void action_Execute(object sender, MenuActionEventArgs e)
    {
        IDiagnosticsService service = 
            e.Context.Services.GetRequiredService<IDiagnosticsService>();

        service.ShowWindow();
    }
}
