C# object not parsing to int

Question

My code looks like this:

var score = ((Dictionary<string, object>)entry.Value)["score"];
print("score: " + score + "!");
FBManager.instance.friends[id].score = (int) score;


//OUTPUT: 
//score: 5!
//InvalidCastException: Specified cast is not valid.

Why can't I cast score to int?

I'm pretty sure entry.Value is a Dictionary<string, object> because I printed entry.Value.GetType() and it said exactly this.

Its unlikely your value is a boxed `int` could it be a decimal or a double, or a string? — TheGeneral, Jan 28 '19 at 23:29
Score wouldn't be an int. Try Convert.ToInt32(score) or parse it — CRice, Jan 28 '19 at 23:33

Convert.ToInt32(score) did the job! I am retrieving this score as a "number" from firebase, thought it would be fine to just cast to int normally, seems I was wrong. Feel free to write it as an answer. — Daniel, Jan 28 '19 at 23:46
firebase calls it number, I don't know the exact type but might be a double — Daniel, Jan 29 '19 at 00:00

See what you get when you do: Console.WriteLine(score.GetType())

If it is System.String you will need to convert (Convert.ToInt32(score)) or int.Parse(score). If it is System.Int32 you should be fine to cast. If it is anything else (double, decimal, etc.) just do the Convert thing :)

Good Luck!
