c# - 在 C# 中创建没有只读属性的目录

Question

当我尝试这样做时:

Directory.CreateDirectory([folderPath]);
File.CreateText([folderPath]);

我有异常(exception) -

System.UnauthorizedAccessException was unhandled by user code
  HResult=-2147024891
  Message=Access to the path 'C:\[folderPath]' is denied.

文件资源管理器显示:

属性:[三态/不确定复选框]只读(仅适用于文件夹中的文件)

但是 Debug.WriteLine(CurrentContestDirectory.Attributes.ToString());显示 - 目录。而不是只读属性!

我在 Google 中寻找“使用 C# 删除目录上的只读属性”，但所有答案都没有帮助我。我需要做什么？

所有代码都在装有 Windows 8 的本地计算机上运行。管理员帐户。如果我手动取消选中 readonly attrinute，代码运行后它会切换回来。

这是一个简单的控制台应用程序。

现在我手动创建文件夹。它默认为只读。

attrib -r C:\new/s in cmd 不工作!!!

如果我手动取消选中只读并单击确定，那么如果我单击属性 - 只读返回

试试这段代码:

 Directory.CreateDirectory(@"c:\newfolder");
 File.CreateText(@"c:\newfolder\textfile.txt");
