How to access an override function into another script (Unity C#)

This is my script

WebSocketNetwork:

public override void GametableHistory(bool success, Int32 gametable_no, Int32 year, Int32 month, Int32 day, Int32 shoe_no, bc_gametable_history_list list)
{
    Debug.Log("GametableHistory gametable_history_list.Count = " + list.Count);

    string s = "";
    for (int i = 0; i < list.Count; i++)
    {
        s += list*.r;*

s += “,”;
}
Debug.Log("Gametable " + gametable_no + " History = " + s);
//PK 4/23/2018
PlayInfo.Instance.gametablehistory = s;
}
WebsocketSession:
abstract public void GametableHistory (bool success, Int32 gametable_no, Int32 year, Int32 month, Int32 day, Int32 shoe_no, gametable_history_list list);
PlayInfo.cs:
public string gametablehistory;
and i have a blank script which is TestScript.cs . What i want here is that on my TestScript.cs i will call the override function and get the gametable_history_list but i don’t know how should i get it from there. Could someone please guide me.

My best suggestion is to put a Property on the WebSocketNetwork script to just get the gametable history you want.
