Question

我想在无序列表中列出文件名（在本例中为文章），但是在获取文件的绝对路径时遇到了问题。如何获得可靠且符合标准的解决方案，以在ASP .NET Core中列出解决方案文件名？

我尝试调用Directory.EnumerateFiles（目录路径参数中是否包含〜）

我还尝试过使用GetFiles，在路径错误上得到类似的结果。

我的代码如下：

<p>
    <ul>
    @foreach (string articulo in Directory.EnumerateFiles("~/Views/Articulo"))
    {
        <li>
            <a asp-controller="Articulo" asp-action="@articulo">@articulo</a>
        </li>
    }
    </ul>
</p>

目前，解决方案上的DOM如下：

-Root Application

  -Views
    -Articulo
      -Todo.cshtml //Only page in the folder

我希望尝试使用正确的锚标记时会出现一些错误，但是却收到了路径错误：


'Directory.EnumerateFiles("~/Views/Articulo")' threw an exception of type 'System.IO.DirectoryNotFoundException'
    Data: {System.Collections.ListDictionaryInternal}
    HResult: -2147024893
    HelpLink: null
    InnerException: null
    Message: "Could not find a part of the path 'C:\\Users\\MyUser\\Documents\\Source\\Repos\\MyRepo\\MySolution\\~\\Views\\Articulo'."
    Source: "System.IO.FileSystem"
    StackTrace: "   at System.IO.Enumeration.FileSystemEnumerator`1.CreateDirectoryHandle(String path, Boolean ignoreNotFound)\r\n   at System.IO.Enumeration.FileSystemEnumerator`1..ctor(String directory, EnumerationOptions options)\r\n   at System.IO.Enumeration.FileSystemEnumerable`1..ctor(String directory, FindTransform transform, EnumerationOptions options)\r\n   at System.IO.Enumeration.FileSystemEnumerableFactory.UserFiles(String directory, String expression, EnumerationOptions options)\r\n   at System.IO.Directory.InternalEnumeratePaths(String path, String searchPattern, SearchTarget searchTarget, EnumerationOptions options)\r\n   at System.IO.Directory.EnumerateFiles(String path)"

EnumerateFiles("~/Views/Articulo")不会扩展~。您需要手动获取真实路径：

@using System.IO
@inject Microsoft.AspNetCore.Hosting.IHostingEnvironment env

<ul>
@{
    var dir = System.IO.Path.Combine(env.ContentRootPath,"Views/Articulo");
}
@if(System.IO.Directory.Exists(dir))
{
    @foreach (string articulo in Directory.EnumerateFiles(dir))
    {
        <li>
            <a asp-controller="Articulo" asp-action="@articulo">@articulo</a>
        </li>
    }
}else{
    <span>"No Files"</span>
}
</ul>

问题列出ASP .NET Core中解决方案文件夹上的每个文件
