[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 />";         }     } }

結果

---------------------------------------- Drive : C:\ Drive Type : Fixed Volume label : File system : NTFS Available space : 47,580,495,872 Bytes Available space : 46,465,328 KB Available space : 45,376.3 MB Available space : 44.31 GB Available space : .04 TB Total available space : 47,580,495,872 Bytes Total size of drive : 125,304,827,904 Bytes ---------------------------------------- Drive : D:\ Drive Type : Fixed Volume label : File system : NTFS Available space : 19,944,185,856 Bytes Available space : 19,476,744 KB Available space : 19,020.26 MB Available space : 18.57 GB Available space : .02 TB Total available space : 19,944,185,856 Bytes Total size of drive : 374,275,567,616 Bytes ---------------------------------------- Drive : E:\ Drive Type : Removable ---------------------------------------- Drive : F:\ Drive Type : Removable ---------------------------------------- Drive : G:\ Drive Type : Removable ---------------------------------------- Drive : H:\ Drive Type : Removable ---------------------------------------- Drive : I:\ Drive Type : CDRom ----------------------------------------

判斷 C: 和 D: 剩餘空間是否小於  10 GB (否則連其他磁碟都測試下去，會判斷錯誤)

bool enough = true; DriveInfo[] allDrives = DriveInfo.GetDrives(); double space = 0.0; double driveCSpace = 0.0; double driveDSpace = 0.0; foreach (DriveInfo d in allDrives) { if (d.IsReady == true) { space = d.AvailableFreeSpace / 1024 / 1024 / 1024; // 換成 GB if (d.ToString() == @"C:\") { driveCSpace = space; if (space < 10.0) enough = false; } if (d.ToString() == "D:\\") { driveDSpace = space; if (space < 10.0) enough = false; } } }
