我听说过框架和BCL中的安全功能,但这是否与防止恶意程序员编写有害软件或防止恶意软件在CLR上运行有关？例如,是否可以在C#中编写一个对Windows文件夹进行有害更改的程序？

我的LINQ2XML查询工作在我的目标的一半:

var XMLDoc = XDocument.Load("WeatherData.xml");

var maximums = from tempvalue in 
                   XMLDoc.Descendants("temperature").Elements("value")
               where tempvalue.Parent.Attribute("type").Value == "maximum"
               select (string)tempvalue;

var minimums = from tempvalue in 
                   XMLDoc.Descendants("temperature").Elements("value")
               where tempvalue.Parent.Attribute("type").Value == "minimum"
               select (string)tempvalue;

List<string> MaxTemps = maximums.ToList();
List<string> MinTemps = minimums.ToList();

但是,我在从XML文档中获取时间信息时遇到了麻烦,因为我必须匹配布局密钥信息(请参阅XML注释),我想知道在LINQ中加入这个的最佳解决方案是什么我现有查询的时间数据:

(顺便说一下,这个XML数据来自Web服务)

大多数编程书籍都会告诉你使用Console.ReadKey()来暂停控制台,但还有更好的选择吗？

Console.WriteLine("Press any key to continue.");
Console.ReadKey();
