我正在尝试使用属性和字符串填充列表

Question

我正在尝试用属性个名称和值填充一个列表，这是我到目前为止的代码...

 public class DirPropeties { 
        public string Name { get; set; }
        public string Path { get; set; }
        public string HiddenStatus { get; set; }
    }
    public static List<string> GetDirAttributes(string path, bool IsHidden = true)
    {

        List<DirPropeties> FolderArrayList = new List<DirPropeties>();
        DirectoryInfo di = new DirectoryInfo(path);
        DirectoryInfo[] subdirectories = di.GetDirectories();
        foreach (DirectoryInfo dir in subdirectories)
        {
            if (IsHidden)
            {
                //FolderArrayList.Add(dir.Name);
                FolderArrayList.Add(new DirPropeties { Name = dir.Name });
            }
            else if ((dir.Attributes & FileAttributes.Hidden) != FileAttributes.Hidden)
            {
                FolderArrayList.Add(new DirPropeties { Name = dir.Name });
            }

        };

        return FolderArrayList;
    }

我是这样称呼它的....

  List<string> DirectoryArrayList = new List<string>();
  DirectoryArrayList = BaseDirectory.GetDirAttributes(FileDetailsViewModel.FolderPath, FileDetailsViewModel.AllowHidden);

我正在尝试像这样访问属性...

   if (folderIndex >= DirectoryArrayList.Count) { break; }
   var folder = DirectoryArrayList[folderIndex];
   var label = new Label()
   {
        Text = folder.Name,
        FontSize = 20,
        VerticalTextAlignment = TextAlignment.Center,
        HorizontalTextAlignment = TextAlignment.Center
   };

我在 FolderArrayList 的 return 上收到以下错误...

无法将类型 'System.Collections.Generic.List' 隐式转换为 'System.Collections.Generic.List'

在 folder.Name 上我得到以下错误...

'string' 不包含 'Name'

的定义

任何人都可以帮助指导我解决这个问题需要做什么吗？

Answer 1

无需在此代码中的任何地方使用 List<string>。变化

public static List<string> GetDirAttributes(string path, bool IsHidden = true)

到

public static List<DirPropeties> GetDirAttributes(string path, bool IsHidden = true)

也改

List<string> DirectoryArrayList = new List<string>();
DirectoryArrayList = BaseDirectory.GetDirAttributes(FileDetailsViewModel.FolderPath, FileDetailsViewModel.AllowHidden);

到

var DirectoryArrayList = BaseDirectory.GetDirAttributes(FileDetailsViewModel.FolderPath, FileDetailsViewModel.AllowHidden);

您还可以改进此代码

if (IsHidden)
{
   //FolderArrayList.Add(dir.Name);
    FolderArrayList.Add(new DirPropeties { Name = dir.Name });
}
else if ((dir.Attributes & FileAttributes.Hidden) != FileAttributes.Hidden)
{
    FolderArrayList.Add(new DirPropeties { Name = dir.Name });
}

到

if (IsHidden || (dir.Attributes & FileAttributes.Hidden) != FileAttributes.Hidden)
{
    FolderArrayList.Add(new DirPropeties { Name = dir.Name });
}
