How can I assign two diffrent values to two variables at the same time

I want to assign values to multiple variables at the same time. I know how it works in python but I need a equivalent for C#.

I found out that if I want to assign a value to a new variable I can do it like this.

int a = 1 , b = 1;
//This works fine but now I need to set the variables again
a = b , b = a + b;
//But i can't do it like that
//I know that in python it would look like this (a , b = b , a+b)

Would b += b; work for you, as a == b?!

I dont know if I got you right, but is this what you are looking for?

static void Main(string[] args)
    {
      int a = 1, b = 1;
      a = b = (a + b);
      Console.WriteLine($"{a} {b}");
      Console.ReadKey();
    }

This is valid C#, using tuples introduced in C# 7:

int (a, b) = (1, 2);
(a, b) = (b, a + b);

I wouldn't say this is idiomatic C# - I've never seen it in the wild, and I don't think many people know that you can do this - but it's valid.

The compiler doesn't actually use the ValueTuple class to do this - it synthesises the following code:

int a = 1;
int b = 2;
int temp1 = b;
int temp2 = a + b;
a = temp1;
b = temp2;
