Tuples and unpacking assignment support in C#?

Question

In Python I can write

def myMethod():     #some work to find the row and col     return (row, col)  row, col = myMethod() mylist[row][col] # do work on this element 

But in C# I find myself writing out

int[] MyMethod() {     // some work to find row and col     return new int[] { row, col } }  int[] coords = MyMethod(); mylist[coords[0]][coords[1]] //do work on this element 

The Pythonic way is obivously much cleaner. Is there a way to do this in C#?

Answer 1

For .NET 4.7 and later, you can pack and unpack a ValueTuple:

(int, int) MyMethod() {     return (row, col); }  (int row, int col) = MyMethod(); // mylist[row][col] 

For .NET 4.6.2 and earlier, you should install System.ValueTuple:

PM> Install-Package System.ValueTuple 

Answer 2

There's a set of Tuple classes in .NET:

Tuple<int, int> MyMethod() {     // some work to find row and col     return Tuple.Create(row, col); } 

But there's no compact syntax for unpacking them like in Python:

Tuple<int, int> coords = MyMethod(); mylist[coords.Item1][coords.Item2] //do work on this element
