如何转换List的类型 <System.IO.FileInfo> 列表 <string> ？

Question

我需要将这种类型的List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();

有人知道怎么回事？

Answer 1

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

或者在Select方法中为您需要的属性更改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();
