Question

I’m trying to create a Dictionary with array of integer, string and boolean data types as values. I figured, I should use object[] as value, so declaration would look so:

Dictionary<long, object[]> netObjectArray = new Dictionary<long, object[]>();

Whenever I try setting its element’s value to something, VS says there was no such key found in the dictionary.

netObjectArray[key][2] = val; // ex: The given key was not present in the dictionary.

How do I work with this correctly?

UPD1:
Somehow, right before throwing this exception, the other dictionary is used without problems in a similar way:

Dictionary<long, Vector2> netPositions = new Dictionary<long, Vector2>();
netPositions[key] = new Vector2(x, y); // works ok

After this locals show the value was assigned and dictionary now contains that entry. Why is this not the case with my other dictionary?

Solution: Before writing a value to an array of values, we must first initialize that array. This code works for me:

try { netObjectArray[key] = netObjectArray[key]; } // if the object is undefined,
catch { netObjectArray[key] = new object[123]; } // this part will create an object
netObjectArray[key][0] = new Vector2(x, y) as object; // and now we can assign a value to it :)

Answer 1

Try something like this:

Dictionary<long, object[]> netObjectArray = new Dictionary<long, object[]>();
for (int i = 0; i < 100; i++) netObjectArray[i] = new object[100];//This is what you're missing.
netObjectArray[key][2] = val;
