我使用_layout cshtml来获得所有相同的开始屏幕。它在索引页面上有效，但是当我转到下一个时，bootstrap的css丢失了。我添加了引导程序布局，但知道它不会在下一个屏幕上进行布局。如果您需要所有代码，我也可以将zip发送给您。索引false仅存在于没有任何内容的布局页面中，当您转到另一个页面时，您会获得布局的文本，而不是引导CSS

答案 0 :(得分：0)
在此示例中使用的所有文件引用都是相对于页面路径的，因此文件必须位于该位置。由于ASP.net将在（例如）http://localhost:33333/处启动默认的“主页”页面，因此浏览器将请求url + css / filename.css，这将适用于第一页。
尽管如果您导航到http://localhost:33333/Home/Index（基本上是同一页面），它将不再起作用，因为浏览器将请求url + / home / index相对路径+ css / filename.css的css （导致找不到http://localhost:333333/home/css/filename.css）
您可以通过以下方法很容易地解决此问题：更改您的layout.cshtml：
<link href="css/bootstrap.css" rel="stylesheet" />
<link href="css/bootstrap-responsive.css" rel="stylesheet" />
对此：
<link href="/css/bootstrap.css" rel="stylesheet" />
<link href="/css/bootstrap-responsive.css" rel="stylesheet" />
<!-- ^ --->
如您所见，文件路径之前有一个斜杠（/）。这将指示浏览器始终使用URL的根，而不是当前位置的相对路径。
