我有一个快速的问题，我正在更新用户，那里的角色和我的modelstate.isvalid失败。因此，用户不会在数据库中获得更新。即使我尝试输入所有字段，我也没有[必填]没有输入的任何内容，但仍然失败。不知道为什么。
这是我的数据模型，我用于编辑/更新用户及角色的控制器动作，这也是我的视图，其中包含视图内部的所有控件。 我真的不确定我的模型状态为何无效，我没有做任何复杂的事情，只是在CRUD中只是一个简单的U，而动作控制器没有在验证模型。

抱歉，没有50个信誉无法发表评论。
如Chetan所说，调试并检查ModelState错误，并检查UserRoles属性是否是问题所在。

如果您使用实体框架，那会很好。那里一切正常。
