如何将List<System.IO.FileInfo>类型转换为List<string>？

Question

我需要将这种类型的列表转换为字符串列表：

var fileName = (new DirectoryInfo(filePath)).GetFiles(".", SearchOption.AllDirectories).Where(a => Regex.IsMatch(a.Name, "^[^*]*" + logSelected + ".jpg$")).ToList();

有人知道这是怎么回事吗？

Answer 1

var fileName = (new DirectoryInfo(filePath))
.GetFiles(".", SearchOption.AllDirectories)
.Where(a => Regex.IsMatch(a.Name, "^[^*]*" + logSelected + ".jpg$"))
.Select(a => a.Name)
.ToList();

或者更改所需属性的Select方法中的a.Name。

Answer 2

尝试添加.Select(fi => fi.Name)

List<string> fileNames = (new DirectoryInfo(filePath)).GetFiles(".", SearchOption.AllDirectories)
            .Where(a => Regex.IsMatch(a.Name, "^[^*]*" + logSelected + ".jpg$"))
            .Select(fi => fi.Name)
            .ToList();

var fileName = new DirectoryInfo(filePath)
                   .GetFiles(".", SearchOption.AllDirectories)
                   .Where(a => Regex.IsMatch(a.Name, "^[^*]*" + logSelected + ".jpg$"))
                   .Select(x => x.Name)
                   .ToList();
