获取硬盘信息仅返回 C 盘信息，不会返回其他信息.c#.

Question

我正在组装一个程序，该程序从PC中提取一堆信息并将其发送到服务器。我目前正在尝试从具有多个驱动器的PC中提取HDD信息，但我只能让它与第一个驱动器一起使用。下面是提取实际驱动器信息的代码，下面是将其写入控制台的代码：

public static string CurrentDiskUsage()
    {
        DriveInfo[] drives = DriveInfo.GetDrives();
        foreach (DriveInfo drive in drives)
        {
            try
            {
                if (drive.IsReady)
                {
                    double result = 100 * (double) drive.TotalFreeSpace / drive.TotalSize;
                    result = Math.Round(result, 2, MidpointRounding.AwayFromZero);
                    string driveInformation = null;
                    driveInformation += drive.Name + "n" + drive.DriveFormat + "n" + "Drive total size: " + FormatBytes(drive.TotalSize) + "n" + "Drive total free space: " + FormatBytes(drive.TotalFreeSpace) + "n" + "Free space as percentage: " + result + "% n ";
                    return driveInformation;
                }
            }
            catch (Exception e)
            {
                return "Fail";
                Console.WriteLine(e);
            }
        }
        return "Fail";
    }

将信息写入控制台

String[] Content  = new string[7]; 
        Content[0] = reportFunctions.GetOsName();
        Content[1] = reportFunctions.IsSoftwareInstalled();
        Content[2] = reportFunctions.CurrentLoggedInUser();
        Content[3] = reportFunctions.GetPcName();
        Content[4] = reportFunctions.CurrentDiskUsage();
        int i = 0;
        while (i < 6)
        {
            Console.WriteLine(Content[i]);
            i++;
        }
}

Answer 1

在第一个循环结束时，你有" return "Fail"; ">

删除此行，因为它会阻止进一步的工作。 您可能还想从异常中删除返回，就像您的 CD 驱动器说驱动器 D 未准备好一样，您的代码将停止，并且也不会继续

编辑：而不是返回 - 因为您还尝试返回一串驱动器信息 - 只需将此数据写出控制台即可。 回归意味着停止做我现在做的事情，回到我所做的事情。

您的代码需要看起来更像这样(PS 您还应该使用 Environment.NewLine 而不是 ，因为这总是返回操作系统的正确换行符(

public static string CurrentDiskUsage()
    {
        String driveInformation ="";   //your code overwrote this with each loop
        DriveInfo[] drives = DriveInfo.GetDrives();
        foreach (DriveInfo drive in drives)
        {
            try
            {
                if (drive.IsReady)
                {
                    double result = 100 * (double) drive.TotalFreeSpace / drive.TotalSize;
                    result = Math.Round(result, 2, MidpointRounding.AwayFromZero);
                    driveInformation += drive.Name + Environment.NewLine + drive.DriveFormat + Environment.NewLine + "Drive total size: " + FormatBytes(drive.TotalSize) + Environment.NewLine + "Drive total free space: " + FormatBytes(drive.TotalFreeSpace) + Environment.NewLine + "Free space as percentage: " + result + "% "+Environment.NewLine;
                }
            }
            catch (Exception e)
            {
                DriveInformation+="Fail:"+Drive.Name+Environment.NewLine+e.Message;
            }
        }
       return driveInformation;
    }
