将特定图像添加到 FileInfo[]

Question

我有一个 FileInfo 对象，它从一个目录接收所有图像：-

string Path = HttpContext.Server.MapPath("~/Content/TempImages/");
DirectoryInfo directory = new DirectoryInfo(Path);
FileInfo[] files = directory.GetFiles();

这可以正常工作并从目录中获取所有图像。但是，我只想从列表（ImagesToShow）中的目录中获取特定图像：-

string Path = HttpContext.Server.MapPath("~/Content/TempDocs/");
foreach (var image in ImagesToShow)
{
  //How do I add all image.imageName to the FileInfo[] object?
}

Answer 1

让它与列表一起工作

      var AllDocs = //List of image names

      string path = HttpContext.Server.MapPath("~/Content/TempImages/");
      List<FileInfo> filelist = new List<FileInfo>();
      foreach (var item in AllDocs)
      {
         filelist.Add(new FileInfo(path + item.ImageName));
      }

然后根据需要转换为数组

      FileInfo[] newfiles = filelist.ToArray();
