c# - 目录中的文件按文件名升序排序

Question

我有一个目录中的文件列表，我想按文件名对它进行排序。

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图片类:

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

如何按照文件名的顺序对文件列表进行排序？

Answer 1

只需更改您的 for 循环:

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:

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);
