How to create SPLink in Sharepoint 2010? Custom Type Field

Question

I'm creating a custom field that stores multiple link inside. The user control works, but it shows me the link like text so now I'm overloading the GetFieldValueAsHtml to modify the HTML..

How can I write down my link as SPLink? Every SPLink Properties is "readonly", so i can't understand HOW to do that!

I'd like to do something like that:

public override string GetFieldValueAsHtml(object value)
{

    string[] address= base.GetFieldValueAsText(value).Split(';');

    foreach (string s in address)
    {
        SPLink link = new SPLink();
        /*
         * MODIFY LINK
         * */
        this.FieldRenderingControl.Controls.Add(link);
    }

    //Code to convert in HTML my Control
}

I think all you need to do in this method is provide a string representation of your field.

You do not need to add a control to controls collection. Sharepoint just takes the your string (html encoded) and puts on the web page. The string representation can be built by StringBuilder class.
