I have this FINAL PAYMENT $25 string on a MVC c# application.
I want to split into FINAL PAYMENT and 25
I tried doing this
string s = "FINAL PAYMENT $25";
string[] str1 = s.Split('$');
//result: 25
How can I get the rest. Can anyone help?

Split method returns a string array, if you need both elements of this array, Try:
string s = "FINAL PAYMENT $25";
string[] resArray = s.Split('$');
var FPayment = resArray[0];
var second25= resArray[1];

You can use indexOf instead of a Split
string s = "FINAL PAYMENT $25";
int index = s.IndexOf("$");
String final_pay = s.Substring(index + 1);

How can I extract this sub-string "60684" from this string "/fa/Viewer/Switcher/60684/0" in c#?

You can use Split method :
string str = "/fa/12012/Switcher/60684/0";
string str2 = str.Split('/')[4];

One way is to use regex:
static void Main()
{
string pattern = #"\/[a-zA-Z]+\/[a-zA-Z]+\/[a-zA-Z]+\/([0-9]+)\/[a-z0-9]+";
var regex = new Regex(pattern);
string path = "/fa/Viewer/Switcher/60684/0";
var match = regex.Match(path);
Console.WriteLine(match.Groups[1].ToString());
}

Like this:
string url = #"/fa/12012/Switcher/60684/0";
string[] NumberAfterSwitcher = url.Split('/');
string num = (NumberAfterSwitcher.Length > 3) ? (String)url.Split('/').GetValue(3) : String.Empty;

I have files on a local server with the address of \\localServerAddress\Folder\Program.exe. I need to remove the server address dynamically and replace it with a different server address that is being selected elsewhere in the form. The server names can be different lengths, therefore, I can not use the string.Substring function.
So given the input
\\localServerAddress\Folder\Program.exe
I would like the result
\\differentServerAddress\Folder\Program.exe

If you are always working with UNCs
Then
string toRemove = new Uri(yourString).host;
string newString = yourString.Replace(String.format(#"\\{0})",toRemove)
, String.format(#"\\{0})",whateveryouwant));

Use this method:
string changeServerInPathString(string originalString, string newServer)
{
List<string> stringParts = originalString.TrimStart('\\').Split('\\').ToList();
stringParts.RemoveAt(0);
stringParts.Insert(0, newServer);
return string.Join("\\", stringParts.ToArray()).Insert(0, "\\\\");
}

You can use something like this:
void Main()
{
string path = #"\\localServerAddress\Folder\Program.exe";
UriBuilder bld = new UriBuilder(path);
bld.Host = "NewServer";
Console.WriteLine(bld.Uri.LocalPath);
}
Result: \\newserver\Folder\Program.exe

string text = #"\\test\FolderName\foo.exe";
text = text.Replace('\\', '-'); \\ this is done as I was not able to make the regex **\\\\\\(.)*?\\** , work.
Regex rg = new Regex("--.*?-"); \\ if in case the above mentioned regex is made to work correctly please replace the regex with the same.
text = rg.Replace(text, "");
Console.WriteLine(text.Replace('-', '\\'));
Console.Read();

You can do this:

Move the selected string to first in comma separated string c#
If my csvstring is : C1,C2,C3
if my selectedstring is : C2
I require an output of : C2,C1,C3

Using the expression power of LINQ:
string cvsstring = "C1,C2,C3";
string selected = "C2";
cvsstring = string.Join(
",",
new[] { selected }.Concat(cvsstring.Split(',').Except(selected));
If there are more than one selected instances, the duplicated will be removed by this code. As the question is very unprecise about that I won't give a solution (using OrderBy, for example).

You can split, sort and join:
string csv = "C1,C2,C3";
string selected = "C2";
csv = String.Join(',', csv.Split(',').OrderBy(s => s == selected ? 0 : 1));

How about this?
var text ="C1,C2,C3";
var splits = text.Split(',');
var results =
String.Join(",",
Enumerable.Concat(
splits.Where(x => x == "C2"),
splits.Where(x => x != "C2")));

Maybe something like this:
var str= "C1,C2,C3";
var selected="C2";
var result= string.Join(",", str.Split(',').OrderBy (s =>s==selected?0:1));

It is pretty easy. Try below given code:
string csvstring = "C1,C2,C3";
string seletedstring = "C2";
string outputstring = selectedstring + csvstring.Replace(seletedstring .ToString(),"");
outputstring = outputstring.Replace(",,","");
