I did not meant you to write code, looking at your code i can see it as webapplication, you can use the above code in global.asax or create HttpModule and configure in you webapplication.

    public void Init(HttpApplication context)
    {
        context.BeginRequest += new EventHandler(Application_BeginRequest);
    }

    private void Application_BeginRequest(object source, EventArgs e)
    {
        HttpContext context = ((HttpApplication)source).Context;
        string ipAddress = context.Request.UserHostAddress;
        if (!IsValidIpAddress(ipAddress))
        {
            context.Response.StatusCode = 403; // (Forbidden)

        }
    }

    private bool IsValidIpAddress(string ipAddress)
    {
        return (ipAddress == "127.0.0.1");
    }

Hope the above code is bit clear and useful.
