How do you assign a dictionary with Lists as values in one statement without using Add()? [duplicate]

Question

I have a dictionary with the value being a list that contains VariableList objects like so

public VariableList { public string VariableName; public bool VariableBoolean; } Dictionary<string, List<VariableList>> myVariableDictionary;

How would I assign this Dictionary with multiple keys including all the objects in the List in one statement without using Add?

@diplomacynotwar Thanks for the link. These don't include a List of Objects. — Sunwoo Yang

Can this be reopened. These answers do not answer my question. — Sunwoo Yang

Can you clarify how an instance of, for example, StudentName is different to an instance of List<VariableList> in the context of instantiating a dictionary? That's in the answer here. Or how is a List<int> different to a List<VariableList> (example here)? If you can explain a substantial way that these are different, I'll gladly reopen your question, but there isn't really a difference here. — ProgrammingLlama

Because one is an object and the other is a list of objects. I'm pretty new to c# so I have no idea if the syntax for creating an object is the same as the syntax for creating a list of objects in a dictionary. And List<int> is a list of ints vs List<VariableList> is a list of objects. Definitely not an obvious distinction for a C# newb. — Sunwoo Yang

Assuming you already have instances of your VariableList class, you can do something like this:

myVariableDictionary = new Dictionary<string, List<VariableList>> { ["string1"] = new List<VariableList> { variableList1, variableList2 ... }, ["string2"] = new List<VariableList> { variableList3, variableList4 ... }, ... };

Thanks for your answer, Aggragoth! and if I didn't have instances of VariableList then I would just write new VariableList { VariableName="blah", VariableBoolean=true } in place of variableList1?
