我 有 一 个 enum ， 我 想 将 其 转换 为 一 个 DropDownList ， 以便 注册 我 目前 正在 使用 的 ：

@Html.DropDownListFor(InputModel => InputModel.Input.UserProffesion.GetValues(typeof(Mindfull8User.Proffesion)).Cast<string>())

中 的 每 一 个
我 收到 一 个 错误 ：
严重 性 代码 描述 项目 文件 行 禁止 显示 状态 错误 （ active ） * * CS0176 * * 无法 使用 示例 引用 访问 成员 " * * Enum . GetValues （ Type ） * * " ;用 一 个 类型 名 来 代替 Mindfull8 来 限定 它
我 该 怎么 解决 这个 问题 ？ 谢谢
