在我的模型中，我的模型是我需要的属性，如：
[Required]
[Range(0, 99, ErrorMessage = "Sorry, you must select a range between 0 - 99.")]
public int MaxConcurrentUsers { get; set; }
所以你会认为当我点击页面上的提交按钮发布值时，因为我为MaxConcurrentUsers键入了一个不正确的值，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modelstate .valid是false，但我希望客户端阻止它进入该方法。我做错了什么？

那么有什么帮助吗？谢谢！

这是应该如何运作的。您仍然可以使用该方法，但可以检查ModelState以决定要执行的操作，例如......
if (ModelState.IsValid) {
// Save, redirect to action
}
return View(model); // send them back to correct the problem!
您还可以在视图上显示错误，因为它们将存在。您可以使用ValidationSummary或拥有单独的ValidationFor元素。

您需要启用客户端验证，unobtrusivejavascript并在母版页中引用脚本文件。
[web.config中]
<appSettings>
<add key="webpages:Version" value="1.0.0.0" />
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
