Provided by Michelle Swann-Renee VP, Professional Solutions Group

Here's some code to find the size of logical drives using Visual Studio .NET.

string[] tempString = Directory.GetLogicalDrives();

foreach(string tempDrive in tempString)

{

cmbDrives.Items.Add(tempDrive);

}

cmbDrives.Selectstring[] tempString = Directory.GetLogicalDrives();

foreach(string tempDrive in tempString)

{

cmbDrives.Items.Add(tempDrive);

}

cmbDrives.SelectedIndex=0;

public sealed class DriveInfo

{

[DllImport("kernel32.dll", EntryPoint="GetDiskFreeSpaceExA")]

private static extern long GetDiskFreeSpaceEx(string lpDirectoryName,

out long lpFreeBytesAvailableToCaller,

out long lpTotalNumberOfBytes,

out long lpTotalNumberOfFreeBytes);

public static long GetInfo(string drive, out long available, out long total, out long free)

{

return GetDiskFreeSpaceEx(drive,out available,out total,out free);

}

public static DriveInfoSystem GetInfo(string drive)

{

long result, available, total, free;

result = GetDiskFreeSpaceEx(drive, out available, out total, out free);

return new DriveInfoSystem(drive,result,available,total,free);

}

public struct DriveInfoSystem

{

public readonly string Drive;

public readonly long Result;

public readonly long Available;

public readonly long Free;

public DriveInfoSystem(string drive, long result, long available, long total, long free)

{

this.Drive = drive;

this.Result = result;

this.Available = available;

this.Total = total;

this.Free = free;

}
