NetShareEnum返回1702

Question

我正在编写一些软件，我需要获取网络共享文件夹列表。我根据这篇文章做了所有的事情 http://www.codeproject.com/Articles/2939/Network-Shares-and-UNC-paths 并且方法NetShareEnum返回1702，并且不返回任何文件夹。

来自文章的编译样本工作正常，我试图通过Resharper解散它，但它也返回1702结果：

protected static void EnumerateSharesNT(string server, ShareCollection shares)
{
    int dwLevel = 2;
    int hResume = 0;
    IntPtr zero = IntPtr.Zero;
    try
    {
        int num2;
        int num3;
        **int num4 = NetShareEnum(server, dwLevel, out zero, -1, out num2, out num3, ref hResume);**
        if (5 == num4)
        {
            dwLevel = 1;
            num4 = NetShareEnum(server, dwLevel, out zero, -1, out num2, out num3, ref hResume);
        }
        if ((num4 == 0) && (num2 > 0))
        {
            Type t = (2 == dwLevel) ? typeof(SHARE_INFO_2) : typeof(SHARE_INFO_1);
            int num6 = Marshal.SizeOf(t);
            int num7 = 0;
            for (int i = zero.ToInt32(); num7 < num2; i += num6)
            {
                IntPtr ptr = new IntPtr(i);
                if (1 == dwLevel)
                {
                    SHARE_INFO_1 share_info_ = (SHARE_INFO_1)Marshal.PtrToStructure(ptr, t);
                    shares.Add(share_info_.NetName, string.Empty, share_info_.ShareType, share_info_.Remark);
                }
                else
                {
                    SHARE_INFO_2 share_info_2 = (SHARE_INFO_2)Marshal.PtrToStructure(ptr, t);
                    shares.Add(share_info_2.NetName, share_info_2.Path, share_info_2.ShareType, share_info_2.Remark);
                }
                num7++;
            }
        }
    }
    finally
    {
        if (IntPtr.Zero != zero)
        {
            NetApiBufferFree(zero);
        }
    }
}

服务器是输入字符串，例如＆＃34; \ 192.168.1.69＆＃34;
