字符串处理函数,使用string非常方便,既支持类似于c语言的数组形式,还有更为方便的字符串运算,读入读出都很方便,另外就是有特殊功能的函数,比如寻找子串的功能,比c友好多了。由于都是线性结构,vector,list,string都有异曲同工之妙。 构造函数 //基本声明strings();//生成一个空字符串ss.~string()//销毁所有字符...

List<string> list = new List<string>() { "a", "b", "c", "d" }; bool isExists = list.Exists(x => x == "a"); 由于Exists方法的参数是一个委托,所以其执行时间比Contains方法要长。但是,当集合中元素比较多且查找条件复杂时,Exists方法的执行时间可能比Contains方法更短。 3、Any方法 Any方...
