在List <tuple> </tuple>中的Item2中搜索

Question

我一直在努力。
我怎么写这个：

/* initialization */ List<Tuple<string, string, string>> mytuple = new List<Tuple<string, string, string>>();
//pseudocode
if(mytuple.Contains("hello") in Item2)
{
    Console.Write("Success");
}

Answer 1

/* initialization */ 

List<Tuple<string, string, string>> mytuple = new List<Tuple<string, string, string>>();


bool containsHello = mytuple.Any(c=>c.Item2.Contains("hello"));

if(containsHello )
{
    Console.Write("Success");
}

Answer 2

您可以使用linq进行检查：

List<Tuple<string, string, string>> mytuple = new List<Tuple<string, string, string>>();

if(mytuple.Where(t=>t.Item2.Contains("hello")).Any())
    Console.Write("Success");
