C# 验证所选内容是否在范围内

在Excel（以及可能的其他Office应用程序）中，

Globals.ThisAddIn.Application.Selection

将具有不同的

类型，具体取决于用户选择的内容：单元格、图表等

如何验证用户选择的单元格

如果Globals.ThisAddIn.Application.Selection.GetType是GetType（Excel.Range），则
不起作用。问题似乎在于
GetType（Excel.Range）
，它返回：

错误BC30560:命名空间中的“范围”不明确
“Microsoft.Office.Interop.Excel”

有什么想法吗


更新
源代码已更改为以下内容，以避免名称空间不明确（如果有人理解此处的名称空间冲突…？）

但是当选择单元格时，
If
语句仍然无法正常运行。
