【问题描述】：
我有一个简短的问题，我正在更新我的用户和角色，而我的 modelstate.isvalid 失败了。所以用户不会在数据库中得到更新。即使我尝试输入所有字段，我也没有任何 [必需] 没有被输入到文本框中，但它仍然失败。不知道为什么。
这是我的数据模型，用于编辑/更新用户和角色的控制器操作，也是我的视图，其中包含视图内部的所有控件。 我真的不确定为什么我的模型状态无效我没有做任何复杂的事情，它只是 CRUD 中的一个简单的 U 并且动作控制器没有验证模型。

你需要调试你的代码并检查
ModeState.Errors属性 -
我没有查看任何 ModelState.Error 或 ModelState.Errors，我什至将它添加为监视变量，但找不到它。我检查了我的模型状态上的每个属性，它没有在任何地方说它失败或抛出异常。我检查了每个键和值...我很困惑为什么它失败了我什至尝试了'ModelState.Remove("Birthday");'在一堆属性上，仍然失败..
-
通过以下帖子尝试找出导致
IsValid属性设置为false 的错误：stackoverflow.com/questions/1791570/…。如果您能得到它们，请将您的问题编辑为附加信息。
