使用c#远程使用WUA
本文关键字：WUA 程使用 使用 | 更新日期: 2023-09-27 18:10:16
我正在尝试连接到远程机器，并确定是否有使用c#和WUApiLib安装的任何Windows更新。这似乎很简单，但是我不知道如何实际连接到远程计算机。
http://msdn.microsoft.com/en-us/library/aa387288(v=VS.85).aspx表示它可以远程使用，除了我不关心的几个例外，但似乎没有关于如何实际连接的文档。我试着传入一个计算机名，但这并不能很好地工作(传入一个包含胡言乱语的名称"成功"与不传递相同，并且结果相同计数，因此我假设string未使用。)
var updateSession = new UpdateSession(dependencies.ComputerName);
var searcher = updateSession.CreateUpdateSearcher();
var results = searcher.Search("IsInstalled=0 and Type='Software'");
有人知道谁通过c#远程使用WUA吗?
几年前我也在寻找同样的东西，并写了一个小脚本。
using System;
using System.Collections.Generic;

}
else

Console.WriteLine("There are no updates for your computer at this time.");
}
Console.WriteLine("Press any key to finalize the process");
Console.Read();
}
//this is my first try.. I can see the need for abstract classes here...
//but at least it gives most people a good starting point.

}
试试这个:
Type t = Type.GetTypeFromProgID("Microsoft.Update.Session", HOSTNAME);
UpdateSession uSession = (UpdateSession)Activator.CreateInstance(t);
IUpdateSearcher uSearcher = uSession.CreateUpdateSearcher();
uSearcher.ServerSelection = ServerSelection.ssWindowsUpdate;
uSearcher.IncludePotentiallySupersededUpdates = false;
uSearcher.Online = false;
ISearchResult sResult = uSearcher.Search(
"IsInstalled=0 And IsHidden=0 And Type='Software'");
