C#获取图像的排序列表[重复]

Question

我正在尝试在一个实用目录中获取图像路径字符串的排序列表。 该目录包含 43 张以数字命名的图片：“1.png”、“2.png”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);
  } 

我得到的结果

由于某种原因，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。

正在寻找解决方案。

谢谢。

Answer 1

原因是它是一个字符串，所以它是按照字符串排序规则排序的。你想要做的是取它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，您可以使用斯科特的建议使用GetFileNameWithoutExtension：

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

请记住，这是一个幼稚的解决方案，它假定所有文件名都是(number).png。如果不是，你可以先检查它是否是一个数字，然后解析
