Loading Class from server C#

I am trying to store my data class on my server as is or even as a text file and then when the application loads it gets the class or text file and I can use it as normal.

Internally everything works just fine, but I can not seem to figure out how to load this "AddressesClass.cs" file from my server and use it in my application.

Once I put that file on my server where do I go from there? what do I do to load it into my application? and once it is loaded into the application do just call to it the same as before?

The class is formed like this:

public class Addresses
{
    public static uint run  = 0x00000001;
    public static uint walk = 0x00000002;
    public static uint jump = 0x00000003;
    public static uint sit  = 0x00000004;
}

and when I use one of the "Addresses" It is called like this

private void checkBox1_CheckedChanged(object sender)
{
    if (checkBox1.Checked)
         gamename.setmemory(Addresses.run, new byte[] { 0x00, 0x00 });
        }
        else
        {
         gamename.setmemory(Addresses.run, new byte[] { 0x00, 0x01 });
        }
}
