查找可用和空闲 RAM 空间时出现未处理的异常。在 Windows 窗体应用程序中获取准确答案，同时在文本框中显示详细信息但在控制台应用程序中获取异常。我添加了所有可能的引用..在编译期间未显示任何错误...

        Console.WriteLine("{0}\n{1}", max_space, Available_space);
    }
}

} 得到这样的错误....

现在您已经添加了所有代码，您的错误在这一行：

Console.WriteLine("{0}\n{1}\n{2}\n{3}\n{4}\n{5}\n",drivename,drivetype,driveformat,max_space,Available_space);

你有 6 个参数，只填写其中的 5 个。每个参数必须有一个对应的值（5 个值的从 0 开始的索引为 0-4）。有关详细信息，请参阅MSDN 中的String.format和Console.WriteLine。

所以那行应该是：

Console.WriteLine("{0}\n{1}\n{2}\n{3}\n{4}",drivename,drivetype,driveformat,max_space,Available_space);
