我正在开发我的第一个MMC SnapIn。我想拥有每个SnapIn配置信息。我需要从SnapIn面板控件访问该信息。我没有看到任何方法从这些控件中找到父SnapIn对象。除了创建静态全局之外,还有其他方法吗?
SnapIn的一部分FormViewDescription似乎使用默认构造函数创建控件:
// Create a form view for the root node.
FormViewDescription fvd = new FormViewDescription();
fvd.DisplayName = "Status";
fvd.ViewType = typeof(SelectionFormView);
fvd.ControlType = typeof(SelectionControl);

答案 0 :(得分:1)
在您的控件(SelectionControl
)中,您可以实现Microsoft.ManagementConsole.IFormViewControl
界面。然后,您会以Initialize
为参数接听对FormView
方法的调用。从这个参数中,您可以访问SnapIn。
以下是一个示例:
public class SelectionControl : UserControl, IFormViewControl
{
...
public void Initialize(FormView view)
{
var snapIn = view.ScopeNode.SnapIn;
...
}
}

您可以使用以下类作为控件的基类,而不是UserControl

(这也会调整其父母的控制权。)
注意:不要访问类的构造函数中的SnapIn
属性。请改用OnInitialize
方法。
