Concat()方法附加两个相同类型的序列,并返回一个新序列(集合)。
IList<string> collection1 = new List<string>() { "One", "Two", "Three" }; IList<string> collection2 = new List<string>() { "Five", "Six"}; var collection3 = collection1.Concat(collection2); foreach (string str in collection3) Console.WriteLine(str);
One Two Three Five Six
IList<int> collection1 = new List<int>() { 1, 2, 3 }; IList<int> collection2 = new List<int>() { 4, 5, 6 }; var collection3 = collection1.Concat(collection2); foreach (int i in collection3) Console.WriteLine(i);

C#或VB.Net中的查询语法不支持Concat运算符。
