C# Example of ValueTuple as Type Parameter of Generic Method

ValueTuple as Type Parameter of Generic Method

A generic method can receive ValueTuple as its type parameter.

class Demo
{
    static void Print<T>(T value)
    {
        Console.WriteLine(value);
    }
    static void Main()
    {
        Print<(string, int)>(("Ajeet", 25));
    }
}

Output

(Ajeet, 25)

Generic Method returning ValueTuple

class Demo
{
    static T Echo<T>(T value)
    {
        return value;
    }
    static void Main()
    {
        var result = Echo<(string Name, double Marks)>(("Ajeet", 91.5));
        Console.WriteLine(result.Name);
        Console.WriteLine(result.Marks);
    }
}

Output

Ajeet

91.5

Generic Method with Type Inference

Type argument often does not need to be written explicitly:

class Demo
{
    static void Show<T>(T data)
    {
        Console.WriteLine(data);
    }
    static void Main()
    {
        Show(("Delhi", 28));
    }
}

Here T is automatically inferred as: (string, int)

So ValueTuple works like any other type in generics.
