我从visual studio 2012专业版运行我的程序作为管理员。我以管理员的身份运行了visual studio。

例如，现在异常错误就行了：

Directory.CreateDirectory(outputtext);

UnauthorizedAccessException 访问路径'C：\ Users \ bout0_000 \ AppData \ Local \ OutputFiles \ outputtext'被拒绝。

还有windows它自己给我一个窗口中间的窗口说：位置不可用然后在里面我看到描述检查网络检查我是否插入了磁盘....等等。

如果我以管理员身份运行我的程序，为什么我无法访问？
在管理员权限不足的情况下，我可以使用哪些目录可以访问任何用户？或者可能没有管理员权限？取而代之的是：

C：\用户\ bout0_000 \应用程序数据\本地\ OutputFiles \的outputText

也许在C：\ Users \ bout0_000 \ AppData \ Local中还有其他位置根本不需要管理员？也许C：\ Users \ bout0_000 \ AppData \ Local \ Temp？

这是完整的异常错误：

System.UnauthorizedAccessException was unhandled
  HResult=-2147024891
  Message=Access to the path 'C:\Users\bout0_000\AppData\Local\OutputFiles\outputtext' is denied.

您的代码中存在一些问题，请尝试修改此版本：

public static void CreateDirectories()
    {

        outputfiles = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "OutputFiles");
        if (Directory.Exists(outputfiles)) Directory.Delete(outputfiles, true);            
        outputtext = outputfiles + "\\outputtext";            
        Directory.CreateDirectory(outputtext);

        outputphotos = outputfiles + "\\outputphotos";
        Directory.CreateDirectory(outputphotos);

        temptxt = outputfiles + "\\txtfiles";
        Directory.CreateDirectory(temptxt);

        tempphotos = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) + "\\photosfiles";
        if (Directory.Exists(tempphotos)) Directory.Delete(tempphotos, true);
        Directory.CreateDirectory(tempphotos);            

        photofilesDir = outputphotos + "\\" + "photosfiles";            
        Directory.CreateDirectory(photofilesDir);

        photofilesDir1 = outputphotos + "\\" + "photosfiles1";
        Directory.CreateDirectory(photofilesDir1);

        photofilesDir2 = outputphotos + "\\" + "photosfiles2";
        Directory.CreateDirectory(photofilesDir2);

        photofilesDir3 = outputphotos + "\\" + "photosfiles3";
        Directory.CreateDirectory(photofilesDir3);
    }

有些说明：

在创建新文件夹之前，您似乎要删除旧的outputfiles文件夹。使用Directory.Delete(path,true)删除将删除所有子目录和文件。因此，删除outputphotos文件夹并创建新文件夹后，所有子文件夹（outputtext，outputfiles，...）显然不存在。这意味着，我们不必检查子文件夹是否存在，只需创建新文件夹即可。同样的逻辑也适用于outputphotos文件夹。
在创建子目录之前，您不必先创建父目录。 Directory.CreateDirectory(path)将在创建子目录（path中的最后一个目录）之前创建所需的所有父目录。

为什么我有时会收到此错误：位置不可用？
