目录中的文件按fileName升序排序 [英] Files in directory sort by fileName ascending

问题描述

我有一个目录中的文件列表，我想按文件名对其进行排序.

I am having a list of files from a directory and I want to sort it out by filename.

这是主要代码:

var localPath = this.Server.MapPath("~/Content/Img/" + type + "/");
var directory = new DirectoryInfo(localPath);
isDirectory = directory.Exists;

if (isDirectory)
{
    foreach (FileInfo f in directory.GetFiles())
    {
        Picture picture = new Picture();

        picture.ImagePath = path;
        picture.CreationDate = f.CreationTime;
        picture.FileName = f.Name;
        listPictures.Add(picture);
    }
}

这是存储所有文件的Picture类:

here is the class Picture where all the files are stored:

public class Picture
{
    public string ImagePath { get; set; }
    public string FileName { get; set; }
    public DateTime CreationDate { get; set; }
}

如何按文件名的顺序对文件列表进行排序?

How do you do to sort a files list by order of FileName?

推荐答案

只需更改您的for循环:

Simply change your for loop :

foreach (FileInfo f in directory.GetFiles().OrderBy(fi=>fi.FileName))
{

}

或者，您可以使用以下代码重写整个循环:

Alternatively, you can rewrite the whole loop using this code :

var sortedFiles = from fi in directory.GetFiles()
                  order by fi.FileName
                  select new Picture { ImagePath = path, CreationDate = f.CreationTime, FileName = f.FileName };

listPictures.AddRange(sortedFiles);
