If there is no space then how do you identify that its last word? e.g. Karim or Rahim goes forOR. If you see this statement, the last word would be forOR,not OR.

Do you have fix words 'OR','AND' etc? You said that you are using some code,but i think you forgot to mention the same. Would you please show us the code you have tried so far?

That is,in any statement you want to remove the last word,regardless of what it is? Right?

If the last word is always AND or OR then it's pretty simple, just use a regex:

C#

public static Regex regex = new Regex("(\\s+(AND|OR)\\s*)$");
                                    ...
string result = regex.Replace(InputText,"");

Hi,

First understand that space(' ') is the separator of characters to make those as words.

1.Remove the last extra space from your string..

C#

string str="Karim OR Rahim OR Motin goes for OR ";
      string strTrimmed=str.Trim();

2.Then Get the substring by finding the last space(' ')

C#

string finalString= strTrimmed.Substring(strTrimmed.LastIndexOf(" ",strTrimmed.Length);

LastIndexOf() -- > is used to find the last index position of a specified character..

Thanks

Try this link http://stackoverflow.com/questions/14825949/replace-last-match-in-string[^]

In this example they have used you would have

string str = "Karim OR Rahim OR Motin goes for OR";

//And then just trim the string after you get your last value removed...
str = ReplaceLastOccurrence(str, "OR", "").Trim();

There are difeferent way that you can do such operation .
Here first remove the spaces by using Trim() operator and then split the string by spaces.

string[] arr=x.Trim().Split(null);

now remove the last word by using LINQ operation

arr = arr.Where((o, i) => i != arr.Length - 1).ToArray();

Last you make a Join operator to join the array items and make a string

x = string.Join(" ", arr);

Hope it helps you

thanks
