c# post或get多个地址的话

Question

c# post或get多个地址的话该怎么样子得思路的？
比如有些网站是get登录的。涉及了3-4个地址我该如何做到自动get登录吗？

    {
        StreamReader sr = null;
        WebRequest wr = null;
        WebResponse ws = null;
        try
        {
            wr = WebRequest.Create(url);
            ws = wr.GetResponse();
            sr = new StreamReader(ws.GetResponseStream(), Encoding.GetEncoding(strEncoding));
            getPageStr = sr.ReadToEnd().Trim();
            return true;
        }
        catch (Exception ex)
        {
            Log(1, "访问页面" + url + "时出错:" + ex.Message);
            return false;
