以下是我们的字符串数组-
string[] arr = { "Java", "HTML", "CSS", "JavaScript"};
使用Aggregate方法并设置Lambda表达式以查找具有更多字符数的字符串。
在这里,结果字符串应具有比初始种子值(即此处的“ jQuery”)更多的字符数。
using System; using System.Linq; class Demo { static void Main() { string[] arr = { "Java", "HTML", "CSS", "JavaScript"}; string res = arr.AsQueryable().Aggregate("jQuery", (longest, next) => next.Length > longest.Length ? next : longest,str => str.ToLower()); Console.WriteLine("String with more number of characters: {0}", res); } }
输出结果
String with more number of characters: javascript
