Is Server.MapPath still the best way?
Server.MapPath 仍然是最好的方法吗？
I have this now DirectoryInfo di = new DirectoryInfo(Server.MapPath("/content/images/thumbs") );but feel it's not the right way.
我现在有这个，DirectoryInfo di = new DirectoryInfo(Server.MapPath("/content/images/thumbs") );但觉得这不是正确的方法。
is there a best practice in MVC for this or is the above still correct?
MVC 中是否有最佳实践，或者以上仍然正确？
采纳答案by Daniel T.
Directory.GetFiles("/content/images/thumbs")
That will get all the files in a directory into a string array.
这会将目录中的所有文件放入一个字符串数组中。

.NET 4.0 has got a more efficient method for this:
.NET 4.0 为此提供了一种更有效的方法：
Directory.EnumerateFiles(Server.MapPath("~/Content/images/thumbs"));
You get an IEnumerable<string>on which you can iterate on the view:
你会得到一个IEnumerable<string>你可以在视图上迭代的：
@model IEnumerable<string>
<ul>
@foreach (var fullPath in Model)
{
var fileName = Path.GetFileName(fullPath);
<li>@fileName</li>
}
</ul>
