字符串数组排序问题

我正在获取文件夹中的所有文件，并将它们放入字符串数组中。我遇到的问题是字符串数组无法正确地对数字大于9的页面进行排序。让字符串数组按正确的方式排序的最简单方法是什么？正如你所看到的，第一个pdf是A10C，它应该显示在A9C下，但它是第一个显示的。B10C:也发生了同样的事情

字符串数组排序问题

您可以使用regex和linq 的组合

var sorted = strs
    .OrderBy(s => DateTime.ParseExact(Regex.Match(s, @"PAPER''('d+)''").Groups[1].Value, "yyyyMMdd", CultureInfo.InvariantCulture))
    .ThenBy(s => Regex.Match(s, @"('w)'d+'w.pdf").Groups[1].Value)
    .ThenBy(s => int.Parse(Regex.Match(s, @"'w('d+)'w.pdf").Groups[1].Value))
    .ThenBy(s => Regex.Match(s, @"'w'd+('w).pdf").Groups[1].Value);
