Find the Size of a Drive
Provided by: Michelle Swann 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);
}
}

}
}
Call:DriveInfoSystem info = DriveInfo.GetInfo("c:")
edIndex=0;
