当我尝试从列表上传文件时出现此错误

“错误：不存在 ID 为 1 的文件。文件列表可能已更改”

当我附加一个文件时它可以工作，但是当列表有多个文件时，我收到错误

调用函数

            foreach (var item in fileList)

            if (!Directory.Exists(_path))
            {
                System.IO.Directory.CreateDirectory(_path);
            }

            Stream stream = entry.OpenReadStream();
            FileStream fs = File.Create(path);
            await stream.CopyToAsync(fs);
            stream.Close();
            fs.Close();

            return path;
        }
        catch (Exception …
