在我的模型所在的类文件中，我具有必需的属性，例如：
[Required]
[Range(0, 99, ErrorMessage = "Sorry, you must select a range between 0 - 99.")]
public int MaxConcurrentUsers { get; set; }
因此，您会认为，当我单击页面上的提交按钮以发布值时，因为我为 MaxConcurrentUsers 键入了不正确的值，所以它不会到达我的 C# 代码中的 actionResult 方法。但确实如此。我注意到的一件事是我的模型状态 .valid 是错误的，但我希望客户端阻止它使用该方法。我究竟做错了什么？
