LINQ的Any方法

返回布尔值，判断集合中是否有元素满足某一条件。

或者你可以如下这样写：

 

source code:

IEnumerable<string> str = new List<string> {                "asdf","fgsdfg","tyuiu","ryury","ituyitu"            };            //if (str.Any(x => x.EndsWith("iu")))            //{            //    Write("true");            //}            //else            //{            //    Write("false");            //}            bool blnResult = str.Any();            blnResult = str.Any<string>((s) =>            {                return s.LastIndexOf("iu") > 0;            });            if (blnResult)            {                Write("true");            }            else            {                Write("false");            }
