I am trying to get query string from url With this code:
this.site_query = Request.Url.Query;
When I have get url:
http://localhost:1751/ar/search?q=سيارة
It gives me blow output in code:
http://localhost:1751/ar/Search?q=%D8%B3%D9%8A%D8%A7%D8%B1%D8%A9&Location=%D8%A3%D8%A8%D9%87%D8%A7,Abha
But I need Arabic text that I send in query string. When query string contains text in English then in c# it is correct.
There is nothing wrong with the second URL you have shown in your answer, it's just being URL encoded due to the limitations of what characters are allowed in URLs.
If you wish to get parts of the query string in code, you can use code like this:
var query = Request.QueryString["q"];
Additionally, if you are building your URLs in code, you should always URL encode and values that may contain non standard characters:
var urlEncodedValue = HttpUtility.UrlEncode(someValue);
As others said already: it's an encoded URL. You can decode with
var decodedUrl = HttpUtility.UrlDecode(url);
or
var decodedUrl = Uri.UnescapeDataString(url);
Is that what you need? If not, show us your expected output.
For this use
string name = HttpUtility.UrlEncode(Encrypt(txtName.Text.Trim()));
string technology = HttpUtility.UrlEncode(Encrypt(ddlTechnology.SelectedItem.Value));
for encoding url.

I'm trying to UrlEncode a web address using Uri.EscapeDataString, but the result isn't correct. Here's an example:
string url = "https://mega.co.nz/#!GVZFwAbB!NzdN2jp7A_WmQBLC4RJrCX8SzixFIEo7oZZARaMAmXQ";
string encodedUrl = Uri.EscapeDataString(url);
Expected result would be:
https%3a%2f%2fmega.co.nz%2f%23!GVZFwAbB!NzdN2jp7A_WmQBLC4RJrCX8SzixFIEo7oZZARaMAmXQ
But the actual one is:
https%253a%252f%252fmega.co.nz%252f%2523%21GVZFwAbB%21NzdN2jp7A_WmQBLC4RJrCX8SzixFIEo7oZZARaMAmXQ
As you can see, there's a bunch of extra %25s that don't belong there. Isn't %25 the encode for "%"? There are no %s in my original string... what's going on?
EDIT: I can't use the System.Web assembly for this project, so unfortunately I can't use the HttpUtility.UrlEncode() method for this.
Well, after searching around a bit more, it seems that this does the job, without relying on system web:
System.Net.WebUtility.UrlEncode(url);
The encoding is the correct one, without %25s.
Uri.EscapeDataString doesn't encode URL. Use HttpUtility.UrlEncode instead.
string url = "https://mega.co.nz/#!GVZFwAbB!NzdN2jp7A_WmQBLC4RJrCX8SzixFIEo7oZZARaMAmXQ";
string encodedUrl = HttpUtility.UrlEncode(url);
Result is:
https%3a%2f%2fmega.co.nz%2f%23!GVZFwAbB!NzdN2jp7A_WmQBLC4RJrCX8SzixFIEo7oZZARaMAmXQ
I am trying to pull a URL out of a string and use it later to create a Hyperlink. I would like to be able to do the following:
- determine if the input string contains a URL
- remove the URL from the input string
- store the extracted URL in a variable for later use
Can anyone help me with this?
Here is a great solution for recognizing URLs in popular formats such as:
www.google.com
http://www.google.com
mailto:somebody#google.com
somebody#google.com
www.url-with-querystring.com/?url=has-querystring
The regular expression used is:
/((([A-Za-z]{3,9}:(?:\/\/)?)(?:[-;:&=\+\$,\w]+#)?[A-Za-z0-9.-]+|(?:www.|[-;:&=\+\$,\w]+#)[A-Za-z0-9.-]+)((?:\/[\+~%\/.\w-_]*)?\??(?:[-\+=&;%#.\w_]*)#?(?:[\w]*))?)/
However, I would recommend you go to http://blog.mattheworiordan.com/post/13174566389/url-regular-expression-for-links-with-or-without-the to see the working example.
Replace input with your input
string input = string.Empty;
var matches = Regex.Matches(input,
#"/((([A-Za-z]{3,9}:(?:\/\/)?)(?:[-;:&=\+\$,\w]+#)?[A-Za-z0-9.-]+|(?:www.|[-;:&=\+\$,\w]+#)[A-Za-z0-9.-]+)((?:\/[\+~%\/.\w-_]*)?\??(?:[-\+=&;%#.\w_]*)#?(?:[.\!\/\\w]*))?)/");
List<string> urlList = (matches.Cast<object>().Select(match => match.ToString())).ToList();
i have an ashx file that requires some query-string values to deliver appropriate images.
The problem is some search engines urlencode then htmlencode those urls in their cache or when they index those.
So for example instead of getting
/preview.ashx?file=abcd.jpg&root=small
i get
/preview.ashx?file=abcd.jpg&root=small
this basically throws off the context.Request.QueryString["root"] so it thinks that there's no variable root
i guess the second key in the querystring is amp;root i.e the part after the & sign.
What i'm wondering is if there's a way to automatically html and urldecode the querystring on serverside so that the program doesn't get confused.
There is no harm in calling HttpUtility.HtmlDecode or HttpUtility.UrlDecode more than once.
string queryString = "/preview.ashx?file=abcd.jpg&root=small";
var parsedString = HttpUtility.HtmlDecode(queryString);
var root = HttpUtility.ParseQueryString(parsedString)["root"];
To URL encode and decode you can use the following methods:
string encoded = System.Web.HttpUtility.UrlEncode(url);
string decoded = System.Web.HttpUtility.UrlDecode(url);
I've seen instances in the past where the Query String has been doubly encoded. In which case you'll need to doubly decode — this may be your issue...
i'm trying to encode an url with the code below;
var encodedUrl = HttpUtility.UrlEncode("http://www.example.com");
var decodedUrl = HttpUtility.UrlDecode("http%3A%2F%2Fwww%2Eexample%2Ecom%2F");
I'm working with the google webmaster tools api and this api expects an URL as shown in the decodedUrl variable above. Every single character is encoded there.
When i use the httputility encode function i get the following result;
http%3a%2f%2fwww.example.com
How can i use the encoding variable in such a way that every character in the url is encoded?
I'm pretty sure that HtmlUtility and AntiXss (another MS tool for encoding urls) aren't going to help here. A "." in a url is considered valid and so doesn't need to be encoded.
I think you're going to have to post-process your encoded string to further encode other characters that are not valid within teh google webmaster tools API.
i.e. do something like this...
var encodedUrl = HttpUtility.UrlEncode("http://www.example.com")
.Replace(".", "%2E");
... assuming that "." is the only character you're having problems with.
The period is not a reserved character in a URL, so it won't be encoded. See this question and answer for an elegant solution.
I need to extract Chinese characters from the query string in an ASP.NET web application.
When I tried it, I get "????" instead of the actual text. I know I need to decode it with UTF-8 but its does not work. I have used:
String text = System.Web.HttpUtility.UrlDecode(Request.QueryString["text"], System.Text.Encoding.UTF8);
but I get "???" back from the operation.
Please help.
There are two cases.
1st Case where your URL is real in chinese, the only function that get it is the Request.RawUrl (and not the Request.QueryString["text"]) From Request.RawUrl you need manually get your Chinese text from text=ελληνικασανκινεζικα.
2nd Case where you have first Encode your URL string before you send it. In this case the code I use is
String text = Server.UrlDecode(Request.QueryString["text"]);
Hope this help.
Note: If you try to make test with Google Chrome, then what you type on url chrome is encode/decode automatically by browser and you are not see what actual you send. Try to use ie, for make your test.
