c# - 来自 LAN 上远程 PC 的日期时间

Question

对于我的应用程序需要，我想从与 LAN 连接的服务器 PC 获取当前的 DateTime。谷歌搜索后，我找到了一篇MSDN 文章。但它是用vb写的。我怎么能在c#中做到这一点？有什么线索吗？

谢谢。

我从另一个答案中得到了解决方案。这对我来说非常有用。

try
{
string pc = "pcname";
//string domain = "yourdomain";
//ConnectionOptions connection = new ConnectionOptions();
//connection.Username = some username;
//connection.Password = somepassword;
//connection.Authority = "ntlmdomain:" + domain;

string wmipath = string.Format("\\\\{0}\\root\\CIMV2", pc);
//ManagementScope scope = new ManagementScope(
//    string.Format("\\\\{0}\\root\\CIMV2", pc), connection);
ManagementScope scope = new ManagementScope(wmipath);
scope.Connect();

ObjectQuery query = new ObjectQuery(
    "SELECT * FROM Win32_LocalTime");

ManagementObjectSearcher searcher =
    new ManagementObjectSearcher(scope, query);

foreach (ManagementObject queryObj in searcher.Get())
{
    Console.WriteLine("-----------------------------------");
    Console.WriteLine("Win32_LocalTime instance");
    Console.WriteLine("-----------------------------------");

    Console.WriteLine("Date: {0}-{1}-{2}", queryObj["Year"], queryObj["Month"], queryObj["Day"]);
    Console.WriteLine("Time: {0}:{1}:{2}", queryObj["Hour"], queryObj["Minute"], queryObj["Second"]);
}
}
catch (ManagementException err)
{
Console.WriteLine("An error occurred while querying for WMI data: " + err.Message);
}
catch (System.UnauthorizedAccessException unauthorizedErr)
{
Console.WriteLine("Connection error (user name or password might be incorrect): " + unauthorizedErr.Message);
}
