获取本地机器IP地址(C#)

如何获本地机器IP地址，引入命名空间 System.Net;
获取IP地址代码如下，在一个按钮事件中获取：
/// <summary>
/// Get Local IP Address
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btnGetIPAddress_Click(object sender, EventArgs e)
{
string strIp = "";
string strHostName = Dns.GetHostName();//Get localhost name
IPAddress[] addresslist = Dns.GetHostByName(strHostName).AddressList;
for (int i = 0; i < addresslist.Length; i++)
{
strIp += addresslist[i].ToString() + "/n";
}
foreach (IPAddress i in addresslist)
{
strIp += i.ToString();
}
txtIPAddress.Text = strIp;
}
编译运行程序即可获得本地机器的IP地址
