Best way to move a group of data between client and server?

As the title says, what is the best way to move groups of data like List<String> or int[]?

Currently, if you send a List<string> from server to client you get:

[   6320141] Error invoking callback for event exampleEvent: System.InvalidCastException: Could not cast event argument from List`1 to List`1

Use JSON and send as string, then decode on the other side?

move groups of data like List<String> or int[]

var list = new[] {"a", "t", "t", "y", "a", "y", "y", "t"};
var result = (from item in list
              group item by item into itemGroup
             select String.Format("{0} - {1}", itemGroup.Key, itemGroup.Count()));

an example in c# ^^
maybe an idea …or like GNG2017 said ^ above
are you asking for example in lua or what?

numbers = {}
str = '1,2,3'
for num in string.gmatch(str, '([^,]+)') do
    table.insert(numbers, tonumber(num))
end

example json-lua

I did not author those examples. Just did a quick search on stackoverflow

In lua you can use json.encode(data) then on the other side you can use json.decode(data).
In C# you can use Newtonesoft( https://www.newtonsoft.com/ ) Json.NET same as in lua, except the syntax

justalemon:

That thing

I know, but is a pain in the ass with the FiveM client.

Receive as IList<object> and take the strings from the object, or use dynamic.

why even when you can just send the data directly since it’s dynamically typed no matter what
