I want to remove the string which starts with FUT. How can I do that ?

Answer 1

You can use

yourString = Regex.Replace(yourString, @"\bFUT\w*?\b", "");

Answer 2

Use Split to 'tokenize' the strings. Then check each substring if it starts with FUT.

string s = "FUTIDX 26FEB2009 NIFTY 0"
string[] words = s.Split(' ');
foreach (string word in words)
{
    if (word.StartsWith("FUT"))
    {
        //do something
    }
}
