What are Tuples in C#4.0?
Tuples has a sequence of elements of different data types. It was introduced to return an instance of the Tuple<T> with no need to specify the type of each element separately.
Let us create a tuple with two elements. The following is how you declare a tuple. −
Tuple<int, string>person = new Tuple <int, string>(32, "Steve");
Now, for the example check for the first item in the tuple, which is an integer −
if (tuple.Item1 == 99) {
Console.WriteLine(tuple.Item1);
}Now check for second item in the tuple, which is a string −
if (tuple.Item2 == "Steve") {
Console.WriteLine(tuple.Item2);
}The following is an example to create a tuple with string and int items −
Example
using System;
using System.Threading;
namespace Demo {
class Program {
static void Main(string[] args) {
Tuple<int, string> tuple = new Tuple<int, string>(50, "Tom");
if (tuple.Item1 == 50) {
Console.WriteLine(tuple.Item1);
}
if (tuple.Item2 == "Jack") {
Console.WriteLine(tuple.Item2);
}
}
}
}Output
50
