[DllImport("coredll.dll")]
private static extern bool GetDiskFreeSpaceEx(string directoryName, ref long
freeBytesAvailable, ref long totalBytes, ref long totalFreeBytes);
调用例子如下：
long freeBytes = 0, totalBytes = 0, totalFreeBytes = 0;
GetDiskFreeSpaceEx("\\Disk1", ref freeBytes, ref totalBytes, ref totalFreeBytes);
string strtotalBytes = "Nor Flash 磁盘空间大小为："+totalBytes.ToString()+"Bytes";

调用 Win32 的申明：
using System.Runtime.InteropServices;
很多客户的应用程序需要独占屏幕，而不需要下方的 Windows 任务栏。因此显示/隐藏
Windows 任务栏是一个很实用的功能。这个时候就需要调用 coredll.dll 里的
FindWindow( … )和 ShowWindow( … )函数来实现任务栏的显示和隐藏（Windows 的任
务
栏实际上也是一个特殊的 Windows 窗口）。
[DllImport("coredll.dll", EntryPoint = "FindWindow")]
public static extern int FindWindow( string lpWindowName, string lpClassName );
[DllImport("coredll.dll", EntryPoint = "ShowWindow")]
public static extern int ShowWindow( int hwnd, int nCmdShow );
public const int SW_SHOW = 5; //显示窗口常量
public const int SW_HIDE = 0; //隐藏窗口常量
下面是一个隐藏/显示 Windows 任务栏的小例子：
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
int Hwnd = FindWindow("HHTaskBar", null);
if (Hwnd != 0)
{
ShowWindow(Hwnd, SW_HIDE); //隐藏任务栏
button2.Enabled = true;
button1.Enabled = false;
}
}
private void button2_Click(object sender, EventArgs e)
{
int Hwnd = FindWindow("HHTaskBar", null);
if (Hwnd != 0)
{
ShowWindow(Hwnd, SW_SHOW); //显示任务栏
button1.Enabled = true;
button2.Enabled = false;
}
}
