How do I retrieve disk information in C#

This class provides methods and properties to obtain information about drives on a computer, such as drive type, available space, total size, and more,
Here's a basic example of how you can get disk information:
Drag and drop the Combobox, Label controls from the Visual Studio toolbox into your form designer, then design a simple UI allows you to select a driver, then display disk information as shown below.
C# get list of drives
Adding a Form_Load event handler to your form allows you to get list of drivers.
//c# get physical drives private void frmGetDiskInfo_Load(object sender, EventArgs e) { // c# get all available drives cboDisk.Items.AddRange(DriveInfo.GetDrives()); }
C# get disk usage
Adding a SelectedIndexChanged event handler to the Combobox allows you to get disk information.
//c# get diskspace private void cboDisk_SelectedIndexChanged(object sender, EventArgs e) { DriveInfo driveInfo = new DriveInfo(cboDisk.Text.Substring(0, 1)); lblType.Text = driveInfo.DriveType.ToString(); if (driveInfo.IsReady) { lblFormat.Text = driveInfo.DriveFormat; lblAvailableFreeSpace.Text = driveInfo.AvailableFreeSpace.ToPrettySize(); lblTotalFreeSize.Text = driveInfo.TotalFreeSpace.ToPrettySize(); lblTotalSize.Text = driveInfo.TotalSize.ToPrettySize(); } else { lblFormat.Text = string.Empty; lblAvailableFreeSpace.Text = string.Empty; lblTotalFreeSize.Text = string.Empty; lblTotalSize.Text = string.Empty; } }
Creating a converter extension method allows you to convert size to prettysize.
// Helper method to format bytes into appropriate unit public static class ConverterExtension { private const long Kb = 1024; private const long Mb = Kb * 1024; private const long Gb = Mb * 1024; private const long Tb = Gb * 1024; public static string ToPrettySize(this long value, int decimalPlaces = 0) { var tb = Math.Round((double)value / Tb, decimalPlaces); var gb = Math.Round((double)value / Gb, decimalPlaces); var mb = Math.Round((double)value / Mb, decimalPlaces); var kb = Math.Round((double)value / Kb, decimalPlaces); string size = tb > 1 ? string.Format("{0}Tb", tb) : gb > 1 ? string.Format("{0} Gb", gb) : mb > 1 ? string.Format("{0} Mb", mb) : kb > 1 ? string.Format("{0} Kb", kb) : string.Format("{0} byte", Math.Round((double)value, decimalPlaces)); return size; } }
This c# example returns disk information including: Total free size, Available free space, Format, Type...etc
