Creating subtuple from a valuetuple

Question

Is there a functionality for C# 7 ValueTuple similar to Python's slicing? The syntax for value tuples in C# is similar to Python but I can't find an elegant way to get subtuple from tuple for example.

In Python 3:

 tuple = (1,2,3)
 subtuple = t[:2]   #subtuple is (1, 2)

In C# 7:

 var tuple = (1,2,3)   //Very similar to Python!
 var subtuple = (tuple.Item1, tuple.Item2)  //Not very elegant, especially for bigger tuples

Answer 1

No, there is nothing like that in C#. Due to the statically-typed nature of C#, a feature like that couldn't work with arbitrary expressions for the slice points.

I think that the closest you can get is to create a bunch of extension methods that have the slice points embedded in their names. E.g.:

public static (T1, T2) Take2<T1, T2, T3>(this (T1, T2, T3) tuple) =>
    (tuple.Item1, tuple.Item2);

var tuple = (1,2,3);
var subtuple = tuple.Take2();

Note that if the tuple members have names, this will strip them off.
