Initialize tuple with empty or null values in C#

Solution 1
If it's an out parameter, the object doesn't need to be initialized before being used. You should just be able to do:
Tuple<string,string> myTuple;
if (myDict.TryGetValue(sdsId, out myTuple))
{
var x = myTuple.Item1;
var y = myTuple.Item2;
}
Solution 2
You don't need to create an instance for an out parameter. Just declare the local variable as Tuple but don't assign a value.
Tuple<string, string> myTyple;

I have this dictionary and tuples set up in SetValue() as below :-
var myDict = new Dictionary<string, Tuple<string, string>>(); private void SetValue() { var myTuple1= Tuple.Create("ABC", "123"); var myTuple2= Tuple.Create("DEF", "456"); myDict.Add("One", myTuple1) myDict.Add("Two", myTuple2) }
I am trying to retrive the tuple in GetValue() as below :-
private void GetValue() { var myTuple = new Tuple<string, string>("",""); //Is this correct way to initialize tuple if (myDict.TryGetValue(sdsId, out myTuple)) { var x = myTuple.Item1; var y = myTuple.Item2; } }
My question is whether this is the correct way to initialize tuple while retrieving the same from a dictionary ? Is there a better code?
var myTuple = new Tuple<string, string>("","");
