获得的 Windows 和 Linux 下的磁盘分区及大小

Windows 和 Linux 都会有一些隐藏的分区，例如 EFI、boot 等。在 Linux 中情况又复杂对得多，例如 Docker 映射的分区/卷等，ram 交换页文件等。
Linux 中 DriveType 嗨哟 Fixed、Ram、CD 等类型，如果要对其进行筛选，编写获取方法是一件较为麻烦的事情。

这时候可以使用 CZGL.SystemInfo 库，在 Nuget 上可以搜索。
使用 var disks = DiskInfo.GetDisks(); 可以直接获取所有磁盘信息，但是这些信息会有很多非物理磁盘。
使用 Linq 表达式可以筛选掉。

            var realDisk = disks.Where(x =>
            x.DriveType == System.IO.DriveType.Fixed &&
            x.TotalSize != 0 && x.FileSystem != "overlay"
            ).Distinct(new DiskInfoEquality());

全部示例代码如下：

using CZGL.SystemInfo;
using System;
using System.Collections.Generic;
using System.Diagnostics.CodeAnalysis;
using System.Linq;
using System.Text;

namespace ConsoleApp7
{
    public class DiskInfoEquality : IEqualityComparer<DiskInfo>
    {
        public bool Equals([AllowNull] DiskInfo x, [AllowNull] DiskInfo y)
        {
            return x.Id == y.Id;
        }

        public int GetHashCode([DisallowNull] DiskInfo obj)
        {
            return obj.Id.GetHashCode();
        }
    }

    class Program
    {
        private static (string Name, int Size) Get(long size)
        {
            if (size < 1024)
            {
                return ("Byte", (int)(size >> 10));
            }
            if (size < 1000 * 1000)
            {
                return ("KB", (int)size / 1000);
            }
            if (size < 1000 * 1000 * 1000)
            {
                return ("MB", (int)(size >> 20));
            }

            if (size < (long)1000 * 1000 * 1000 * 1000)
            {
                return ("GB", (int)(size >> 30));
            }

            if (size < (long)1000 * 1000 * 1000 * 1000 * 1000)
            {
                return ("TB", (int)(size >> 40));
            }
            throw new Exception();
        }
        static void Main(string[] args)
        {
            var disks = DiskInfo.GetDisks();
            foreach (var item in disks)
            {
                var tmpa = Get(item.FreeSpace);
                var tmpb = Get(item.TotalSize);
                var tmpc = Get(item.UsedSize);
                Console.WriteLine(@$"ID:{item.Id}
Name:{item.Name}
DriveType:{item.DriveType}
FileSystem:{item.FileSystem}
FreeSpace:{tmpa.Size} {tmpa.Name}
TotalSize:{tmpb.Size} {tmpb.Name}
UsedSize: {tmpc.Size} {tmpc.Name}
");
            }

            Console.WriteLine("经过检查后，发现以下磁盘可能是磁盘分区，请确认是否正确：");
            var realDisk = disks.Where(x =>
            x.DriveType == System.IO.DriveType.Fixed &&
            x.TotalSize != 0 && x.FileSystem != "overlay"
            ).Distinct(new DiskInfoEquality());

            foreach (var item in realDisk)
            {
                var tmpa = Get(item.FreeSpace);
                var tmpb = Get(item.TotalSize);
                var tmpc = Get(item.UsedSize);
                Console.WriteLine(@$"ID:{item.Id}

DriveType:{item.DriveType}
FileSystem:{item.FileSystem}
FreeSpace:{tmpa.Size} {tmpa.Name}
TotalSize:{tmpb.Size} {tmpb.Name}
UsedSize: {tmpc.Size} {tmpc.Name}
");
            }

            Console.WriteLine("CD，USB等存储设备不计入此列表，Docker的虚拟磁盘也不考虑");
            Console.ReadKey();
        }
    }
}
