c# - arp -a 和路由打印

Question

我需要编写一个程序来显示这些信息:

• 网络统计
• TCP/UDP 连接
• 有关IP的信息 ipconfig/all
• arp-a
• 路线图

我已经有了其中的大部分，但是我在 route print 和 arp -a 方面遇到了问题。我不想使用 Process.Start() 执行此命令，因为它看起来不太壮观:

Process p = new Process ();

p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
p.StartInfo.UseShellExecute = false;
p.StartInfo.FileName = "route";
p.StartInfo.Arguments = "PRINT";
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.CreateNoWindow = true;
p.StartInfo.StandardOutputEncoding = Encoding.Default;
p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
p.Start();
TextBox1.Text = p.StandardOutput.ReadToEnd();

我想使用 foreach 循环将数据放入 ListView 或 DataGrid 列中。有没有人能帮助我？我怎样才能将这些数据放入每一列:目的地、网络掩码、网关、接口(interface)、指标和永久路由？对于 ARP，物理地址的互联网地址类型？

非常感谢。我已经用 WMI CODER CREATOR 编写了指导和 IPv4routetable 以下代码:

private void button1_Click(object sender, EventArgs e)
{
    try
    {
        ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_IP4RouteTable");
        ListViewItem buf;

        foreach (ManagementObject queryObj in searcher.Get())
        {
            string destination = queryObj["Destination"].ToString();
            string mask = queryObj["Mask"].ToString();
            string metric = queryObj["Metric1"].ToString();
            string interfaceIndex = queryObj["InterfaceIndex"].ToString();
            string nexthop = queryObj["NextHop"].ToString();
            string protocol = queryObj["Protocol"].ToString();
            string type = queryObj["Type"].ToString();
            string status;
            if (queryObj["Status"] != null)
            {
                status = queryObj["Status"].ToString();
            }
            else
            {
                status = string.Empty;
            }


            buf = new ListViewItem(new string[] { destination, mask, metric, interfaceIndex, nexthop, protocol, status, type });
            list_route.Items.Add(buf);

        }
    }
    catch (ManagementException ex)
    {
        MessageBox.Show("An error occurred while querying for WMI data: " + ex.Message);
    }
}

只是不知道在哪个类上我找了关于arp-a的资料，在google上找不到。如果有人知道他在问答案。如果哪位有WMI Coder Creator等其他有用的辅助工具，不胜感激。

我找到了一些资料。关于 GetIpNetTable 但我不能在 GUI 应用程序中使用此函数，将结果传递给 ListView 。 :(
