C# Registration Steam

It is impossible to register. Writes:
{\"bSuccess\":false,\"details\":\"captcha data missing!\"}
I checked all the CAPTCHA correctly. The request also seems true. What's wrong?
PS I using xNet
public bool accaunt_create(AccauntData ad)
{
HttpRequest httpRequest = new HttpRequest();
httpRequest.AllowAutoRedirect = true;
httpRequest.UserAgent = "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.85 Safari/537.36 OPR/32.0.1948.38";
httpRequest.Cookies = cook;
httpRequest.AddParam("accountname", ad.accountname);
httpRequest.AddParam("password", ad.password);
httpRequest.AddParam("email", ad.email);
httpRequest.AddParam("captchagid", captchaID);
httpRequest.AddHeader("captcha_text", ad.captcha_text);
httpRequest.AddParam("i_agree", "1");
httpRequest.AddParam("ticket");
httpRequest.AddParam("count", "4");
httpRequest.AddHeader("X-Requested-With", "XMLHttpRequest");
httpRequest.AddHeader("X-Prototype-Version", "1.7");
httpRequest.AddHeader("Accept", "text/javascript, text/html, application/xml, text/xml, */*");
var res = httpRequest.Post("https://store.steampowered.com/join/createaccount/").ToString();
return false;
}

maybe this
httpRequest.AddParam("captchagid", captchaID);
have to be this:
httpRequest.AddParam("captchaid", captchaID);

Replicating this PUT request in RestSharp

Below is what the request looks like in the web app.

The data is in the request payload field
{"table":"users","settings":[{"name":"dnd","value":"true"}]}
Below is my current C# RestSharp code
// Initiate Rest Client
var client = new RestClient("http://myurl.com");
var request = new RestRequest("resturl/restrequest");
// Set headers, method and cookies
request.Method = Method.PUT;
request.AddHeader("Content-Type", "application/json");
request.AddHeader("Accept", "*/*");
request.AddCookie("session", sessionKey);
// Set Data format
request.RequestFormat = DataFormat.Json;
// Set Data
string theString = "{'table':'users','settings':[{'name':'dnd','value':'true'}]}";
request.AddBody(theString);
// Execute
var test123 = client.Execute(request);
I've been able to successfully do all my GET/POST calls however PUT has not been successful.

Instead of adding a string as the payload consider adding an object:
request.AddBody(new { table = "users", settings = new[] { new { name = "dnd", value = "true" } } });

Log in to site programmatically and redirect browser to signed in state

I want to sign in to a site when a link is clicked and then redirect the browser there with a signed in session. Im having some troubles and here is what Ive tried:
First I get the session cookies from the login site:
CookieContainer cookies= new CookieContainer();
HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create("http://someuri.com");
myHttpWebRequest.CookieContainer = cookies;
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
myHttpWebResponse.Close();
Then I post to the sign in page to get signed in:
HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create("http://signInURL.com");
getRequest.CookieContainer = cookies;
getRequest.Method = WebRequestMethods.Http.Post;
getRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2";
getRequest.AllowWriteStreamBuffering = true;
getRequest.ProtocolVersion = HttpVersion.Version11;
getRequest.AllowAutoRedirect = true;
getRequest.ContentType = "application/x-www-form-urlencoded";
byte[] byteArray = Encoding.ASCII.GetBytes(PostParameterStringWithSignInInfo);
getRequest.ContentLength = byteArray.Length;
Stream newStream = getRequest.GetRequestStream();
newStream.Write(byteArray, 0, byteArray.Length);
newStream.Close();
HttpWebResponse getResponse = (HttpWebResponse)getRequest.GetResponse();
Then I figured I need to set the cookies to the client:
CookieCollection cooki = getRequest.CookieContainer.GetCookies(new Uri("http://someUri.com"));
for(int i = 0; i < cooki.Count; i++)
{
Cookie c = cooki[i];
Response.Cookies.Add(new HttpCookie(c.Name, c.Value));
}
And then redirect to where you end up being signed in:
Response.Redirect("http://URLwhenBeingSignedIn.com");
This doesnt work. When redirected Im still logged out.
Tried to do this with Fiddler and succeeded to sign in and get redirected:
Get the session cookies:
GET / HTTP/1.1
Content-type: application/x-www-form-urlencoded
Host: someuri.com
Post to the sign in page to get signed in:
POST /signIn HTTP/1.1
Accept: text/html, application/xhtml+xml, */*
Referer: http://someuri.com
Accept-Language: en-GB,en;q=0.7,tr;q=0.3
User-Agent: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)
Content-Type: application/x-www-form-urlencoded

Content-Length: 90
DNT: 1
Host: signInURL.com
Pragma: no-cache
Cookie: JSESSIONID=fromBefore; Cookie2=fromBefore
PostParameterStringWithSignInInfo
Perhaps there's an easier way than the one I thought of now that you can see the fiddler requests that works, if so I'm happy to see it.

Where is the error in this code (c# HttpWebRequest)

return new StreamReader(((HttpWebResponse)request.GetResponse()).GetResponseStream()).ReadToEnd();

you cannot add headers via HttpWebRequest.Headers.Add()
certain headers are set to be restricted
private static readonly string[] RestrictedHeaders = new[]
{
"Accept", "Connection", "Content-Type", "Content-Length", "Date", "Expect", "Host", "Range", "Referer", "User-Agent"
};
all the headers listed above are not to be added directly, they can only be set by using
//HttpWebRequest.[TheProperty] = value;

You forgot to "fill" the post-data?!? for what i see you're sending a request that only has headers...

HttpWebRequest: how to identify as a browser?

The question is how to construct HttpWebRequest so queried server will think it comes from a browser?

You could set the User-Agent HTTP request header.
var request = (HttpWebRequest)WebRequest.Create("http://www.google.com");
request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2";
or if you work with a WebClient:
using (var client = new WebClient())
{
client.Headers[HttpRequestHeader.UserAgent] = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2";
...
}
