这个问题在这里已有答案：
我是相当新的c＃并且每天学习更多虽然我坚持这个并且找不到类似的东西
在表单加载时，我想显示：*当前窗口用户*当前IP *主机名
和其他系统信息直接进入标签。任何指向我可以学习如何做这个或一个例子的指针
非常感激
所有这些答案都来自现有的StackOverflow帖子。你真的应该努力一点。
当前用户：
string userName =
System.Security.Principal.WindowsIdentity.GetCurrent().Name;
labelName.Text = userName;
目前的IP：
public static string GetLocalIPAddress()
{
var host = Dns.GetHostEntry(Dns.GetHostName());
foreach (var ip in host.AddressList)
{
if (ip.AddressFamily == AddressFamily.InterNetwork)
{
return ip.ToString();
}
}
throw new Exception("No network adapters with an IPv4 address in the system!");
}
labelName.Text = GetLocalIPAddress();
主机名：
string hostName = System.Net.Dns.GetHostName();
labelName.Text = hostName;
多年来我用这个课程来获取一些基本的机器信息。
