Try
尝试
Path.GetPathRoot(Environment.GetFolderPath(Environment.SpecialFolder.System));
That will return (normally) C:\
这将返回（通常）C:\
But it depends on how you define the "main" hard drive. This will give you the drive Windows is installed on.
但这取决于您如何定义“主”硬盘。这将为您提供安装 Windows 的驱动器。

This should work (assuming you want the drive that windows is on):
这应该可以工作（假设您想要 Windows 所在的驱动器）：
string rootDrive = Path.GetPathRoot(Environment.SystemDirectory);
