I have a certificate data (byte array):
var cert = new X509Certificate2(certBytes);
var serialBytes = cert.GetSerialNumber();
var serialString = cert.SerialNumber;
when converting serialBytes to hex format:
BitConverter.ToString(serialBytes).Replace("-","")
it gives a different value than serialString
Because you should read the documentation:
X509Certificate.GetSerialNumber
Returns the serial number of the X.509v3 certificate as an array of bytes in little-endian order.
X509Certificate2.SerialNumber
Gets the serial number of a certificate as a big-endian hexadecimal string.

Url is like That:
http://localhost:620251/Default.aspx/?group=Bkgbdsconsumer & Retailmailinglist
Want the group value on cs page:
Bkgbdsconsumer & Retailmailinglist
I ma doing this:
string group= HttpUtility.UrlEncode(Request.QueryString["group"]);
EDIT:
Ok, as I thought, there is no space before and after & in your URL.
Also port number is too big 620251 (max is 65535 as I think).
// 'fixed' port number
string url = #"http://localhost:12345/Default.aspx/?group=Bkgbdsconsumer&Retailmailinglist";
Uri myUri = new Uri (url);
var groupValue = HttpUtility.ParseQueryString (myUri.Query)["group"];
string[] allKeysWithoutValue = HttpUtility.ParseQueryString (myUri.Query).GetValues (null);
Now allKeysWithoutValue is an array with one element Retailmailinglist.

I am working on a stenography project and I want to generate same series random numbers on both side for encoding and decoding using any key.
The Random class in c# has a constructor that takes in an int value as a seed
Random rand1 = new Random((int) DateTime.Now.Ticks & 0x0000FFFF);

I need a regular expression to extract number 513922 from this string.
Error detected (513922: settings can not be applied.), param d1=0.0, d2=0.0 in operation mode
If you insist on regular expression:
string source =
"Error detected (513922: settings can not be applied.), param d1=0.0, d2=0.0 in...";
// 513922
string result = Regex.Match(source, #"(?<=\()[0-9]+(?=:)").Value;
// if you want integer representation:
int number = int.Parse(result);

I want convert 1,2,3,4,5,6,7,8,9,10 String to Double.
I tried Convert.ToDouble(String); and Double.Parse(String); but returned 1.0
How to convert multi comma string to double?
Thanks for help.
From the looks of your question you actually have 10 numbers not 1. Use this code:
var nums = "1,2,3,4,5,6,7,8,9,10";
var digits = nums.Split(',').Select(r => Convert.ToDouble(r)).ToArray();
// the result will be an array of doubles, also this only works with .NET 3.5 or better.
Let me know if this works for you.
