Using one method to set values of different variables loading by parameter

Question

It is possible to write one method that can set value to different variables which are loaded by parameter?

I think something about like this:

void SetBooleanValue(bool myVariable, bool newValue)
{
    myVariable = newValue;
}

and then use this like that:

bool isConnected = false;
bool isFinished = true;

public ClassConstructor()
{
    SetBooleanValue(isConnected, true);
    SetBooleanValue(isFinished, false);
}

The problem is my method only gets value of isConnected and isFinished and can't modify original values of those variables.

How to get reference to them?

@JuanCarlosMendoza sorry for Java tag but i think it will work in java and c# the same way — mmm, Oct 30 '17 at 14:20
@MadMike6661 It will not work in Java because Java doesn't have the possibility to pass a value type by "ref". You would need to "box" that value into some kind of object. — Darjan Bogdan, Oct 30 '17 at 14:22
While your question makes sense in java and c#, solutions look very different, as the `ref`-keyowrd from C# doesn´t exist in Java. — MakePeaceGreatAgain, Oct 30 '17 at 14:22

That´s what the ref-keyword is for:

void SetBooleanValue(ref bool myVariable, bool newValue)
{
    myVariable = newValue;
}

Use it like this:

SetBooleanValue(ref isConnected, true);

This keyword enables you to set the provided instance to something different.
