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 have a string like:
43965.96000,16933.986,404689.986,5814892.171,77.464,52.47585589,13.59670032,77.464,0.675,-0.223
I want to just keep the string which is bold in characters between commas. How can I do that?

To take your question literally, you could do write a method to split the string by comma and just take the element at the 5th index:
string ParseData(string data)
{
return data.Split(',')[5];
}
So you'll be able to do something like:
string data = "43965.96000,16933.986,404689.986,5814892.171,77.464,52.47585589,13.59670032,77.464,0.675,-0.223";
string result = ParseData(data); // Result = "52.47585589"

I am having file name as below.
i need only sample.xml as result.
sample.xml.jued.783737377365474.da
Please help me on this. thanks in Advance

File name can have one extension only:
string path = "sample.xml.jued.783737377365474.da";
// ".da"
var ext = Path.GetExtension(path);
However, in case you have a origin.extension.[some data].da pattern, you can split the file name by . and take first two items:
// sample.xml
var origin = String.Join(".", Path
.GetFileName(path)
.Split(new char[] { '.' }, 3)
.Take(2));

I have two urls:
http://sp2013/sites/1234
and
http://sp2013/pwa/projectsites/projectdetails.aspx?projuid=1234-123-123-123456-123456
I want to get from the first url the last part (always a number)
1234
and from the second url also the last part (guid)
1234-123-123-123456-123456
How could i achieve this through RegEx or maybe with string operations in C#?

string s = "http://sp2013/sites/1234";
var firstURLlastPart = new Uri(s).Segments.Last();
string s = "http://sp2013/pwa/projectsites/projectdetails.aspx?projuid=1234-123-123-123456-123456";
var secondURLlastPart = s.Split('=').Last();

Just split at '/' and take the last chunk for the first case.
str.Split('/').Last()
Split at '=' and take last chunk for second case
str.Split('=').Last()

(?!\/|\=).[-0-9]+$
It's working for both. But it also accepts if in first example will be number in format like this:
12345-4568

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);

Convert a string into mac address as example 0000001 need to change as 00:00:01 In php i can get it by this $HexVal=rtrim(strtoupper(chunk_split($hexval, 2, ':')),':'); i need exactly same in C#.
I have the first 6 value as 00:01:AB and i got the last six value from a decimal number. If i input 1 then it needs to change as 00:00:01. so then i con-cat to get my full mac as 00:00:AB:00:00:01.

OK got it,,
var temp = Regex.Replace("000001", ".{2}", "$0:");
var tempo = temp.Remove(temp.Trim().Length - 1);//or
var tempo = temp.Trim(':');
