获取远程计算机的日期时间？ [英] Get remote PC's date time?

有什么类可用来获得远程计算机的日期时间在.net中？为了做到这一点，我可以使用计算机名称或时区。对于每一种情况下，是否有不同的方式来获取当前日期时间？我使用Visual Studio 2005。

推荐答案

我给你一个解决方案，它使用 WMI 。您可能会或可能不需要的域和安全信息：

I give you a solution which uses WMI. You may or may not need the domain and security information:

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);
}
