示例

下面的示例演示如何从派生类的构造函数调用基 ExternalDataEventArgs 构造函数。 此示例摘自“订单状态机”SDK 示例。 有关详细信息，请参阅 订购状态机示例。

public override void Dispose()
{
    try
    {
        IDesignerLoaderHost host = LoaderHost;
        if (host != null)
        {
            host.RemoveService(typeof(IIdentifierCreationService));
            host.RemoveService(typeof(IMenuCommandService));
            host.RemoveService(typeof(IToolboxService));
            host.RemoveService(typeof(ITypeProvider), true);
            host.RemoveService(typeof(IWorkflowCompilerOptionsService));
            host.RemoveService(typeof(IEventBindingService));
        }
    }
    finally
    {
        base.Dispose();
    }
}

Public Overrides Sub Dispose()
    Try
        Dim host As IDesignerLoaderHost = LoaderHost
        If host IsNot Nothing Then
            host.RemoveService(GetType(IIdentifierCreationService))
            host.RemoveService(GetType(IMenuCommandService))
            host.RemoveService(GetType(IToolboxService))
            host.RemoveService(GetType(ITypeProvider), True)
            host.RemoveService(GetType(IWorkflowCompilerOptionsService))
            host.RemoveService(GetType(IEventBindingService))
        End If
    Finally
        MyBase.Dispose()
    End Try
End Sub

ExternalDataEventArgs()
