LINQ 如何集合连接集合
有个不定元素的数组string[] str
{
a="a";
b="b";
........
}
里面的元素不确定

foreach(var c in str){
var list=a.Where(uu => uu.name.Contains(c)));
}

如何把每个搜索出来的结果list合并到一个集合里面？谢谢！

C# code

 public static void Main()        {            string[] str = { "abc", "bc", "cd", "ef" };            var list = (from a in str                       where a.Contains('c')                       select a).ToList();            var list2 = (from a in str                         where a.Contains('b')                         select a).ToList();            List<string> ll = new List<string>();            ll.AddRange(list);            ll.AddRange(list2);            foreach(var cc in ll)                Console.WriteLine(cc);        }
