How can i declare a value that will change with target value

How can i declare a value that will change with target value. like;

bool isInFrozen = true;
bool frozen = isInFrozen;
    
print(frozen); // Prints True

isInFrozen = false; // Value changed

// Im wanting to print isInFrozen's changed value
print(frozen); // But still prints true

>Solution :

frozen needs to be a reference

bool isInFrozen = true;
ref bool frozen = ref isInFrozen;

Console.WriteLine(frozen); // Prints True

isInFrozen = false; // Value changed

Console.WriteLine(frozen); // Now prints False

For more details on c# references, take a look at the docs
