Question

我正在尝试在特定目录中获取图像路径字符串的排序列表。该目录包含43个以数字命名的图像：“1.png”，“2. png”，依此类推。

这是我的代码：

  var sorted = Directory.GetFiles(Directory.GetCurrentDirectory(), "*.png").OrderBy(f => f);           
  foreach (string img in sorted) 
  {
   Console.WriteLine(img);
  }

我得到的结果

出于某种原因，我无法获得正确的按字母顺序排序的列表，我也尝试使用LINQ Sort()方法，但没有成功。

寻找解决方案。

感谢。

原因是它是一个字符串，因此它按字符串排序规则排序。你想要做的是取数字部分并按顺序排序：

Directory.GetFiles(Directory.GetCurrentDirectory(), "*.png")
         .OrderBy(f => int.Parse(f.Split('.')[0]));

如果不使用Split，您可以使用Scott的建议来使用GetFileNameWithoutExtension：

Directory.GetFiles(Directory.GetCurrentDirectory(), "*.png")
         .OrderBy(f => int.Parse(Path.GetFileNameWithoutExtension(f)));

请记住，这是一个天真的解决方案，假设所有文件名都是(number).png。如果不是这种情况，您可以先检查它是否为数字，然后解析
