'How to auto update class values when selected?

I have Server1.cs and Server2.cs in project. How can I update all the values in MainServer.cs class when the combobox selects to 'Server1'? (Like copy Server1.cs to MainServer.cs). I want that idea but I searched in Google, not found.

enter image description here

Server1.cs Class:

 class Server1
{
    public static int ServerID = 0x1;
    public static int ServerPointer = 0x54A;
    public static int ServerOffset1 = 0x5FF;
    public static int ServerOffset2 = 0x604;
    public static int ServerOffset3 = 0x66A;
}

Sever2.cs Class:

  class Server2
{
    public static int ServerID = 0x3;
    public static int ServerPointer = 0x53A;
    public static int ServerOffset1 = 0x56F;
    public static int ServerOffset2 = 0x614;
    public static int ServerOffset3 = 0x68A;
}

MainServer.cs Class:

class MainServer
{
    public static int ServerID = Server1.ServerID or Server2.ServerID;
    public static int ServerPointer;
    public static int ServerOffset1;
    public static int ServerOffset2;
    public static int ServerOffset3;
}

When selected combobox:

   if (comboBox1.SelectedItem.ToString() == "Server1")
        {
            MainServer = Server1();
        }
        else if (comboBox1.SelectedItem.ToString() == "Server2")
        {
            MainServer = Server2();
        }
