其实一行代码就可以了,不用写那么多循环,先看看老外写的代码
using System; class Program { static void Main() { string [] array = { " cat " , " dot " , " perls " }; // Use Array.Exists in different ways. bool a = Array.Exists(array, element => element == " perls " ); bool b = Array.Exists(array, element => element == " python " ); bool c = Array.Exists(array, element => element.StartsWith( " d " )); bool d = Array.Exists(array, element => element.StartsWith( " x " )); // Output. Console.WriteLine(a); Console.WriteLine(b); Console.WriteLine(c); Console.WriteLine(d); }
string[] SetSelectIds = string[] { "aa", "bb", "cc" };
string id = string "bb";
if (Array.Exists(SetSelectIds, element => element.Equals(id)))
Array.IndexOf(SetSelectIds, id) >= 0;
