LINQ不提供我期望的输出

Question

 var CC = new List<Company>();

            Company t1 = new Company();
            t1.Comp = "ABC";
            t1.Area = "Area1";
            t1.Link = "https://www.google.com";
            CC.Add(t1);

            Company t2 = new Project();
            t2.Comp = "DEF";
            t2.Area = "Area2";
            t2.Link = "https://www.yahoo.com";
            CC.Add(t2);

            var a = from p in CC where p.Comp == "ABC" && p.Area == "Area1"
                    select p.Link;

Console.WriteLine(a);

            Console.Read();

在上面的代码中,我希望将输出视为"www.google.com".

但我所看到的是.

我哪里错了？我怎样才能看到"www.google.com"？

Answer 1

a正在返回,IEnumerable就像你想访问谷歌然后你想要foreach它或做FirstOrDefault()

foreach(var item in a)
{
 Console.WriteLine(a);
}
