FeatureConnectorAttribute 类
更新：2007 年 11 月
指示处理 FeatureProvider 所必需的 FeatureConnector<TFeatureProviderType> 的类型。
命名空间： Microsoft.Windows.Design.Features
程序集： Microsoft.Windows.Design.Extensibility（在 Microsoft.Windows.Design.Extensibility.dll 中）
语法
声明
<AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple := True)> _
Public NotInheritable Class FeatureConnectorAttribute _
Inherits Attribute
用法
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
备注
将 FeatureConnectorAttribute 应用于自定义 FeatureProvider 类，以指定发布 FeatureProvider 所必需的服务的 FeatureConnector<TFeatureProviderType>。
示例
下面的代码示例演示如何使用 FeatureConnectorAttribute 将 FeatureConnector<TFeatureProviderType> 类与名为 DiagnosticsMenuProvider 的自定义功能提供程序相关联。有关完整的代码列表，请参见如何：创建自定义功能连接器。
' 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();
}
}
