Search in Item2 in List<Tuple>

问题

I've been struggling.
How do I write this:

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

回答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");
}

回答2:

You can use linq to check it:

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

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