initiate class

Unity Engine
1

i have a class with the characteristics of a player (ID, name, points… etc.)
I want to assign values to this class 20 times.
I fail with the message: NullReferenceException: Object reference not set to an instance of an object
If it were a GameObject, I would know
newPlayer = Instantiate(emptyPrefab, new Vector3(0,0,0), transform.rotation);
would work.
Here is what I have tried:
public DataClass[ ] myDataClass;
in void start:
myDataClass = new DataClass[20];
for (int i = 1; i < 20; i += 1)
{
myDataClass*.ID = i;*
}
And there is already the error message.
PLEASE can someone help?

for (int i = 1; i < 20; i += 1)

i should start at 0, because arrays in C# start at 0.

EDIT: it won’t let me post the code, hang on while I try and get it to work :hushed:

Got it - it should be this:

myDataClass[i].ID = i;
