C# 属性更改|调用成员名称|模糊匹配交换

我在运行时遇到以下错误：AmbiguousMatchException找到了不明确的匹配

有人知道原因是什么吗

班 截图 堆栈跟踪 System.Reflection.AmbiguousMatchException是aufgetreten

问题是，HtUserGroupSetup中的Permissions属性隐藏了基类HtUserGroup的Permissions属性

---

重命名HtUserGroupSetup中的Permissions属性解决了问题。

您应该发布整个异常，包括stack@OfirWinegarten请添加整个类。您需要添加更多上下文。另外，避免发布截图。改为张贴代码/文本。最有可能的错误发生在PropertyChanged事件的处理程序中，因此与CallerMemberName无关。但如果没有完整的堆栈跟踪，很难说现在发布的内容是不完整的，因为只包含最后一次调用。确保类中没有与CurrentUserGroupSetup和CurrentUserGroupSetup同名但大小写不同的属性。
