按对象列表排序

如果只想在数字之后对这些文件进行排序,可以传递一个比较器来实现所需规则的排序。这将根据文件名的编号对其进行排序:

List<string> files = new List<string>
    {
        "552939_VVIDEO9.mp4",
        "552939_VVIDEO8.mp4",
        "552939_VVIDEO13.mp4",
        "552939_VVIDEO12.mp4",
        "VOD1.mp4",
        "552939_VVIDEO6.mp4",
        "VOD2.mp4",
        "552939_VVIDEO2.mp4",
        "552939_VVIDEO16.mp4",
        "552939_VVIDEO10.mp4",
        "552939_VVIDEO3.mp4",
        "552939_VVIDEO11.mp4",
        "552939_VVIDEO4.mp4",
        "552939_VVIDEO1.mp4",
        "552939_VVIDEO15.mp4",
        "552939_VVIDEO14.mp4",
        "552939_VVIDEO17.mp4"
    };
        files.Sort((a, b) => {
            int an = 0;
            int bn = 1;
            var regex = new Regex("([0-9]+).mp4", RegexOptions.IgnoreCase);
            var aGroups = regex.Match(a).Groups;
            var bGroups = regex.Match(b).Groups;
            var aidx = aGroups.Count > 1 ? 1 : 0;
            var bidx = bGroups.Count > 1 ? 1 : 0;
            an = int.Parse(aGroups[aidx].Value);
            bn = int.Parse(bGroups[bidx].Value); 
            if (an == bn)
                return 0;
            if (an < bn)
                return -1;
            return 1;
        });
        foreach (var file in files)
        {
            Console.WriteLine(file);
        }
        Console.ReadKey();

输出:

VOD1.mp4
552939_VVIDEO1.mp4
VOD2.mp4
552939_VVIDEO2.mp4
552939_VVIDEO3.mp4
552939_VVIDEO4.mp4
552939_VVIDEO6.mp4
552939_VVIDEO8.mp4
552939_VVIDEO9.mp4
552939_VVIDEO10.mp4
552939_VVIDEO11.mp4
552939_VVIDEO12.mp4
552939_VVIDEO13.mp4
552939_VVIDEO14.mp4
552939_VVIDEO15.mp4
552939_VVIDEO16.mp4
552939_VVIDEO17.mp4

注意:可能需要一些额外的错误检查。当然,您可以扩展这个比较器函数来处理您想要的任何规则。
