Obtained Disk Partitions and Sizes on Windows and Linux

Windows and Linux both have hidden partitions such as EFI, boot, etc. The situation in Linux is much more complex, for example, with Docker mapped partitions/volumes, RAM swap files, etc.

In Linux, DriveType can be types like Fixed, Ram, CD, etc. Writing a method to filter these can be quite troublesome.

At this time, you can use the CZGL.SystemInfo library, which can be searched on Nuget.

By using var disks = DiskInfo.GetDisks();, you can directly obtain information about all disks; however, this information includes many non-physical disks. You can filter them out using a Linq expression.

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

The complete example code is as follows:

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}

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}

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();
        }
    }
}
