如何在C#中将元组初始化为空元组？
将元组初始化为空元组-
Tuple<string, string> myTuple;
如果要检查元组中的值，则该值是否为null-
示例
using System;
namespace Demo {
class Program {
static void Main(string[] args) {
Tuple <int, string> tuple = new Tuple<int, string>(10, null);
if (tuple.Item1 == 10) {
Console.WriteLine(tuple.Item1);
}
if (tuple.Item2 == null) {
Console.WriteLine("Item is null");
}
}
}
}
