hi Experts,
Say my current page url has got http://localhost:2345/english/faq.aspx?faqid=12123&cid=4545&intcid=65456&h=man
string excludeQuerystring = DynConfig.Item("GoogleSEOLinkSettings/ExcludeQuerystring"); //this is the list of my exclude querystring (cid,intcid,del)

querystring = HttpContext.Current.Request.Url.AbsoluteUri.Split('?')[1]; //I will get faqid=12123&cid=4545,intcid=65456

StringBuilder fullQueryString = new StringBuilder();

if (!string.IsNullOrEmpty(excludeQuerystring) && !string.IsNullOrEmpty(querystring))
	string[] strEQ = excludeQuerystring.Split(',');  //making a array of excluded querystrings

	NameValueCollection navValues = HttpUtility.ParseQueryString(querystring);  //getting the list of querystring in NameValueCollection

	if (navValues.Count > 0)
		string[] strQ = navValues.AllKeys;

querystring= ?+faqid=12123&h=man //here I want updated querystring which does not have any querystring which is there in my excludeQuerystring

I am confused how to get this, actually I want to make a function which will do this all.

Please suggest!!


I changed the code for above implementation. Please see the code.

 protected void Page_Load(object sender, EventArgs e)
            string querystring = string.Empty;

            string excludeList = "cid,intcid,del";

            if (!string.IsNullOrEmpty(excludeList))
                string getFinalString = GetQueryString(excludeList);
                getFinalString = "?" + getFinalString;

        public string GetQueryString(string excludeArray)
            string retQueryString = string.Empty;
            if (excludeArray.IndexOf(",") != -1)
                string[] strArray = excludeArray.Split(",".ToCharArray());
                NameValueCollection filtered = new NameValueCollection();

                if (filtered.HasKeys())
                    foreach (string strMatch in strArray)
                    retQueryString = filtered.ToString();

            return retQueryString;

Now when I am going to convert back to querystring from NameValueCollection existing keys
retQueryString = filtered.ToString();
what code will be written for this as I am not able to convert it back to string.
