C#显示本机IP和MAC地址的代码!
下面这段程序为什么不能显示IP地址呢????
编译运行后会在textBox1里显示System.String[],
请问:这是哪里错了呀????????    

                    ManagementClass   mc;
                        mc   =   new   ManagementClass( "Win32_NetworkAdapterConfiguration ");
                        ManagementObjectCollection   moc   =   mc.GetInstances();
                        //MessageBox.Show(moc.Count.ToString());
                        foreach   (ManagementObject   mo   in   moc)
                        {
                                if   (mo[ "IPEnabled "].ToString()   ==   "True ")
                                {
                                        textBox1.Text   +=   mo[ "IPAddress "].ToString();
                                        textBox2.Text   +=   mo[ "MACAddress "].ToString();
                                }
                        }    


------解决方案--------------------
获取本机IP
string strHostIP= " ";
IPHostEntry oIPHost=Dns.Resolve(Environment.MachineName);
if(oIPHost.AddressList.Length> 0)
strHostIP=oIPHost.AddressList[0].ToString();
获取MAC
using System.Management;

//get the MAC address

ManagementClass mc=new ManagementClass( "Win32_NetworkAdapterConfiguration ");

ManagementObjectCollection moc=mc.GetInstances();

string[] MacAddress=new string[2];

int ii=0;

foreach(ManagementObject mo in moc)

{

if((bool)mo[ "IPEnabled "]==true)

{

MacAddress[ii]=mo[ "MacAddress "].ToString();

ii++;

}

mo.Dispose();

}
------解决方案--------------------
你错在 if (mo[ "IPEnabled "].ToString() == "True ")
这行
if (mo[ "IPEnabled "].ToString() == "true ")
就对了，建议不要textBox1.Text +=
先定义个String ，最后在赋值

------解决方案--------------------
将其改为
ManagementClass mc;
mc = new ManagementClass( "Win32_NetworkAdapterConfiguration ");
ManagementObjectCollection moc = mc.GetInstances();
//MessageBox.Show(moc.Count.ToString());
foreach (ManagementObject mo in moc)
{
if (mo[ "IPEnabled "].ToString() == "True ")
