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);

I have a string "ABD-DDD-RED-Large" and need to extract "DDD-RED"
using the Split I have:
var split = "ABD-DDD-RED-Large".Split('-');
var first = split[0];
var second = split[1];
var third = split[2];
var fourth = split[3];
string value = string.Join("-", second, third);
just wondering if there's a shorter code

If you just want the second and third parts of an always 4 part (delimited by -) string you can one line it with LINQ:
string value = string.Join("-", someInputString.Split('-').Skip(1).Take(2));
An input of: "ABD-DDD-RED-Large" would give you an output of: "DDD-RED"

Not enough information. You mentioned that string is not static. May be Regex?
string input = "ABD-DDD-RED-Large";
string pattern = #"(?i)^[a-z]+-([a-z]+-[a-z]+)";
string s = Regex.Match(input, pattern).Groups[1].Value;

Use regex
var match = Regex.Match(split, #".*?-(.*?-.*?)-.*?");
var value = match.Success ? match.Groups[1].Value : string.Empty;

I'm going out on a limb and assuming your string is always FOUR substrings divided by THREE hyphens. The main benefit of doing it this way is that it only requires the basic String library.
You can use:
int firstDelIndex = input.IndexOf('-');
int lastDelIndex = input.LastIndexOf('-');
int neededLength = lastDelIndex - firstDelIndex - 1;
result = input.Substring((firstDelIndex + 1), neededLength);
This is generic enough to not care what any of the actual inputs are except the hyphen character.
You may want to add a catch at the start of the method using this to ensure there are at least two hyphen's in the input string before trying to pull out the requested substring.

I have string
string AccountName= "123456789 - Savings - 20$"
Now I want to select the Accountname Savings only. That means the part between -s.
That data is dynamic data. So, Could you please give me an idea to get the part of string between two -s. i.e AccountName= "Savings".
Thank you in advance..!!

One of the ways you can to that:
Split string by '-'
Get the position 1 of array
Trim value to remove spaces
var AccountNameSplited= AccountName.split('-')[1].Trim();
You should be defensive in this cases:
var AccountNameBt = AccountName.Split('-');
var AccountNameBtPos1 = string.Empty;
if (AccountNameBt != null && AccountNameBt.Count() > 0)
AccountNameBtPos1 =AccountNameBt[1].Trim();

Assuming your string will always have only two -s, you could using the following to get the substring between them. If this is not the case please modify the question to better describe the issue.
string myString = AccountName.Split('-')[1];
Check out https://msdn.microsoft.com/en-us/library/system.string.split(v=vs.110).aspx for more information on the Split method in the string class.

How about:
string AccountName = "123456789 - Savings - 20$";
String[] tokens = AccountName.Split(new[] { " - " }, StringSplitOptions.RemoveEmptyEntries);
AccountName = tokens.ElementAtOrDefault(1); // Savings
If it's possible that there are no spaces:
String[] tokens = AccountName.Split(new[] { '-' }, StringSplitOptions.RemoveEmptyEntries);
AccountName = tokens.ElementAtOrDefault(1)?.Trim();

Use Regex:
AccountName = Regex.Match(AccountName, #"-\s*(.*?)\s*-").Groups[1].Value;

I have a string which has a following format:
"####/xxxxx"
The text before the "/" is always an integer and I need to read it. How do I get only the integer part of this string (before the "/")?
Thank you for your help.

You can split the string on / and then use int.TryParse on the first element of array to see if it is an integer like:
string str = "1234/xxxxx";
string[] array = str.Split(new []{'/'}, StringSplitOptions.RemoveEmptyEntries);
int number = 0;
if (str.Length == 2 && int.TryParse(array[0], out number))
{
//parsing successful.
}
else
{
//invalid number / string
}
Console.WriteLine(number);

Use IndexOf and Substring:
int indexOfSlash = text.IndexOf('/');
string beforeSlash = null;
int numBeforeSlash = int.MinValue;
if(indexOfSlash >= 0)
{
beforeSlash = text.Substring(0, indexOfSlash);
if(int.TryParse(beforeSlash, out numBeforeSlash))
{
// numBeforeSlash contains the real number
}
}

Another alternative: use a regular expression:
var re = new System.Text.RegularExpression(#"^(\d+)/", RegexOptions.Compiled);
// ideally make re a static member so it only has to be compiled once
var m = re.Match(text);
if (m.IsMatch) {
var beforeSlash = Integer.Parse(re.Groups[0].Value);
}

I have a string and I want to delete everything before a phrase, and then delete everything after a different phrase. i.e.,
myString = "words words words FIRSTPHRASE these words I want SECONDPHRASE but not these words"
So the new string would be "these words I want".

Use String.Substring and String.IndexOf, it has also an overload with a start index:
string myString = "words words words FIRSTPHRASE these words I want SECONDPHRASE but not these words";
string result = myString;
int indexOfFirstPhrase = myString.IndexOf("FIRSTPHRASE");
if(indexOfFirstPhrase >= 0)
{
indexOfFirstPhrase += "FIRSTPHRASE".Length;
int indexOfSecondPhrase = myString.IndexOf("SECONDPHRASE", indexOfFirstPhrase);
if (indexOfSecondPhrase >= 0)
result = myString.Substring(indexOfFirstPhrase, indexOfSecondPhrase - indexOfFirstPhrase);
else
result = myString.Substring(indexOfFirstPhrase);
}
Demonstration

Something like this?
string theWordsIWant = Regex.Replace(myString, #"^.*?FIRSTPHRASE\s*(.*?)\s*SECONDPHRASE.*$", "$1");
