在項目2中搜索列表<Tuple>

Question

我一直在掙扎。
我如何寫：

/* 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查詢它：

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

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