Office加载项和功能区：初始化顺序？

Question

加载项和功能区的初始化顺序是什么？加载项对象是否始终在功能区之前创建，或者这可能会有所不同？

Answer 1

通过调用addin对象的RequestService方法来创建功能区。IRibbonExtensibility实现。
因此，插件必须已经存在。

在功能区XML模板中，您可以在功能区CS文件中执行以下操作：

public partial class ThisAddIn {
    private RibbonManager ribbon;
    ///<summary>Returns an object that extends a feature in the 2007 Microsoft Office system.</summary>
    ///<param name="serviceGuid">A System.Guid that identifies an extensibility interface 
    ///that is supported by applications in the 2007 Microsoft Office system.</param>
    ///<returns>An object that implements the extensibility interface that is identified by serviceGuid.</returns>
    protected override object RequestService(Guid serviceGuid) {
        if (!String.IsNullOrEmpty(JournalPath) && serviceGuid == typeof(IRibbonExtensibility).GUID) {
            if (ribbon == null)
                ribbon = new RibbonManager();
            return ribbon;
        }

        return base.RequestService(serviceGuid);
    }
}
