Sample Code:

    [DllImport("wtsapi32.dll", SetLastError=true)]
    public static extern bool WTSEnumerateServers(
        String pDomainName,
        int Reserved,
        int Version,
        ref IntPtr ppServerInfo,
        ref uint pCount
    );
    [DllImport("wtsapi32.dll")]
    static extern void WTSFreeMemory(IntPtr pMemory);
    [StructLayout(LayoutKind.Sequential)]
    public struct WTS_SERVER_INFO
    {
        [MarshalAs(UnmanagedType.LPStr)]public String pServerName;
    }
    static void Main(string[] args)
    {
        IntPtr pInfo = IntPtr.Zero;
        uint count = 0;
        Int32 dataSize = Marshal.SizeOf(typeof(WTS_SERVER_INFO));
        if (WTSEnumerateServers(null, 0, 1, ref pInfo, ref count))
        {
        Int64 current = (int)pInfo;
        for (int i = 0; i < count; i++)
        {
            WTS_SERVER_INFO WTScsi = (WTS_SERVER_INFO)Marshal.PtrToStructure((IntPtr)current, typeof(WTS_SERVER_INFO));
            current += dataSize;
            String sname = WTScsi.pServerName;
            Console.WriteLine(sname);
        }
        WTSFreeMemory(pInfo);
        }
        Console.ReadLine();
    }
