MSDN "ShellBrowser"
[解决办法]
引用System32中SHDocVw.dll和Shell32.dll

C# code

private void Form1_Load(object sender, EventArgs e)        {            Shell32.ShellClass shell = new Shell32.ShellClass();            SHDocVw.ShellWindows windows = shell.Windows() as SHDocVw.ShellWindows;            string[] lines = new string[windows.Count];            for (int i = 0; i < windows.Count; i++)            {                SHDocVw.ShellBrowserWindow win =  windows.Item(i) as SHDocVw.ShellBrowserWindow;                lines[i] = win.LocationName;            }            memoEdit1.Lines = lines;        }
