c#获得排序的图像列表

本文关键字：图像 列表 排序 | 更新日期: 2023-09-27 18:05:09

我试图在一个特定的目录中获得图像路径字符串的排序列表。目录包含43张以数字命名的图片:"1.png"， "2.png"，等等。

这是我的代码:

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

得到的结果

由于某种原因，我不能得到一个正确的按字母顺序排序的列表，我也尝试使用LINQ Sort()方法，没有成功。

寻找解决方案

谢谢。

c#获得排序的图像列表

原因是它是一个字符串，所以它按照字符串排序规则排序。你要做的是取其中的数字部分并按它排序:

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，它假设所有的文件名都是(number).png。如果不是，可以先检查是否为数字，然后解析
