システム上の論理ドライブ(C#)のリスト、およびその容量と空き容量を取得するにはどうすればよいですか?
foreach (var drive in DriveInfo.GetDrives())
{
double freeSpace = drive.TotalFreeSpace;
double totalSpace = drive.TotalSize;
double percentFree = (freeSpace / totalSpace) * 100;
float num = (float)percentFree;
Console.WriteLine("Drive:{0} With {1} % free", drive.Name, num);
Console.WriteLine("Space Remaining:{0}", drive.AvailableFreeSpace);
Console.WriteLine("Percent Free Space:{0}", percentFree);
Console.WriteLine("Space used:{0}", drive.TotalSize);
Console.WriteLine("Type: {0}", drive.DriveType);
}
多分これはあなたが望むものです:
listBox1.Items.Clear();
foreach (DriveInfo f in DriveInfo.GetDrives())
listBox1.Items.Add(f);
この情報は、Windows Management Instrumentation(WMI)で取得できます。
using System.Management;
ManagementObjectSearcher mosDisks = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
// Loop through each object (disk) retrieved by WMI
foreach (ManagementObject moDisk in mosDisks.Get())
{
// Add the HDD to the list (use the Model field as the item's caption)
Console.WriteLine(moDisk["Model"].ToString());
}

これはすばらしいコードです。
ObjectQuery query =
new ObjectQuery("SELECT * FROM Win32_LogicalDisk WHERE DriveType=3"); // Create query to select all the hdd's
ManagementObjectSearcher searcher =
new ManagementObjectSearcher(scope, query); // run the query
ManagementObjectCollection queryCollection = searcher.Get(); // get the results
string sVolumeLabel = "";
string[,] saReturn = new string[queryCollection.Count, 7];
int i = 0; // counter for foreach
foreach (ManagementObject m in queryCollection)
{
if (string.IsNullOrEmpty(Convert.ToString(m["VolumeName"]))) { sVolumeLabel = "Local Disk"; } else { sVolumeLabel = Convert.ToString(m["VolumeName"]); } // Disk Label
string sSystemName = Convert.ToString(m["SystemName"]); // Name of computer
string sDriveLetter = Convert.ToString(m["Name"]); // Drive Letter
decimal dSize = Math.Round((Convert.ToDecimal(m["Size"]) / 1073741824), 2); //HDD Size in Gb
decimal dFree = Math.Round((Convert.ToDecimal(m["FreeSpace"]) / 1073741824), 2); // Free Space in Gb
decimal dUsed = dSize - dFree; // Used HDD Space in Gb
int iPercent = Convert.ToInt32((dFree / dSize) * 100); // Percentage of free space
saReturn[i,0] = sSystemName;
saReturn[i,1] = sDriveLetter;
saReturn[i,2] = sVolumeLabel;
saReturn[i,3] = Convert.ToString(dSize);
saReturn[i,4] = Convert.ToString(dUsed);
saReturn[i,5] = Convert.ToString(dFree);
saReturn[i,6] = Convert.ToString(iPercent);
i++; // increase counter. This will add the above details for the next drive.
