[研究] [C#] [ASP.NET] 取得硬碟剩餘空間 (Windows 2016)

2017-02-17

Visual Studio 2015 with Update 3
Windows Server 2016

測試發行到 Windows Server 2016 的 IIS 上可以跑

Default.aspx.cs
using System;
using System.IO;

namespace WebApplication2
{
    public partial class Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            DriveInfo[] allDrives = DriveInfo.GetDrives();

            foreach (DriveInfo d in allDrives)
            {
                Label1.Text = Label1.Text + "----------------------------------------" + "<br />";
                Label1.Text = Label1.Text + "Drive : " + d.Name + "<br />";
                Label1.Text = Label1.Text + "Drive Type : " + d.DriveType + "<br />";
                if (d.IsReady == true)
                {
                    Label1.Text = Label1.Text + "Volume label : " + d.VolumeLabel + "<br />";
                    Label1.Text = Label1.Text + "File system : " + d.DriveFormat + "<br />";

                    Label1.Text = Label1.Text + "Available space : " + d.AvailableFreeSpace.ToString("###,###,###,###,###.##") + " Bytes <br />";
                    Label1.Text = Label1.Text + "Available space : " + (Decimal.Divide(d.AvailableFreeSpace, 1024) ).ToString("###,###,###,###,###.##") + " KB <br /> ";
                    Label1.Text = Label1.Text + "Available space : " + (Decimal.Divide(d.AvailableFreeSpace, 1024) / 1024).ToString("###,###,###,###,###.##") + " MB <br /> ";
                    Label1.Text = Label1.Text + "Available space : " + ((double)d.AvailableFreeSpace / 1024 / 1024 / 1024).ToString("###,###,###,###,###.##") + " GB <br /> ";
                    Label1.Text = Label1.Text + "Available space : " + (d.AvailableFreeSpace / 1024.0 / 1024 / 1024 / 1024).ToString("###,###,###,###,###.##") + " TB <br /> ";

                    Label1.Text = Label1.Text + "Total available space : " + d.TotalFreeSpace.ToString("###,###,###,###,###") + " Bytes<br />";
                    Label1.Text = Label1.Text + "Total size of drive : " + d.TotalSize.ToString("###,###,###,###,###") + " Bytes<br />";
                }
            }
            Label1.Text = Label1.Text + "----------------------------------------" + "<br />";
        }
    }
}
