Initializers "Update"

[srburton]

My idea is that an upgrade initializer would be possible to save code lines

Initializers

var people  = new People{
   Name = "Renato"
}

//Update object

with people{
   Age = "M",
  Date = "2018/06/15"
}

//Output

Renato
M
2018/06/15

That code doesn't seem at all readable or clear.

Maybe this could be better?

with people {
  Age = "M",
  Date = "2018/06/15"
};

Do you mean the C# 8.0's candidate #162?

with expressions are different from the with statement that is frequently requested. The former creates a new instance with the modified properties whereas the latter modifies an instance in place.

Very good solution liked

with people { Age = "M", Date = "2018/06/15" };

I'd love the former, if it means I can have an immutable type and then get a new instance back with just the specified member changed.

Reminds me of the with statement in Pascal and JavaScript.

Something like this would be interesting, although I think I'd prefer it only be available for setting fields and properties (similar to the already existing object initializers.) (As opposed to the Pascal and JavaScript implementations where you're essentially changing this for a particular scope.)

That being said, the number of times I've wanted something like this have been pretty limited.
