Getting a list of logical drives
提问by PaulB
How can I get the list of logial drives (C#) on a system as well as their capacity and free space?
如何获取系统上的逻辑驱动器 (C#) 列表及其容量和可用空间？
回答by Eoin Campbell
You can retrieve this information with Windows Management Instrumentation (WMI)
您可以使用 Windows Management Instrumentation (WMI) 检索此信息
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());
}
Theres more info here about the attribute you can poll
这里有关于您可以轮询的属性的更多信息

Their example has more robust, but here's the crux of it
他们的例子更强大，但这里是它的关键
string[] drives = System.IO.Directory.GetLogicalDrives();
foreach (string str in drives)
{
System.Console.WriteLine(str);
}
You could also P/Invokeand call the win32 function (or use it if you're in unmanaged code).
您还可以P/Invoke并调用 win32 函数（或者如果您在非托管代码中使用它）。
That only gets a list of the drives however, for information about each one, you would want to use GetDrivesas Chris Ballance demonstrates.
但是，这只会获取驱动器的列表，有关每个驱动器的信息，您可能希望像 Chris Ballance 演示的那样使用GetDrives。

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);
}

maybe this is what you want:
也许这就是你想要的：
listBox1.Items.Clear();
foreach (DriveInfo f in DriveInfo.GetDrives())
listBox1.Items.Add(f);

This is a wonderful piece of code.
这是一段美妙的代码。
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.
}
