Remove last word from string

Accepted answer

Try,

string oldString = "Chain - 99.6";
int lastIndex = oldString.LastIndexOf("-");
string newString = oldString;
if (lastIndex != -1)
{
newString = oldString.Remove(lastIndex).Trim();
}
Response.Write(newString);

ok..in that situation you can put if condition...

string oldString="Chain -99.6";
if(oldString.Contains("-"))
{
string newString = oldString.Substring(0,oldString.LastIndexOf("-")).Trim();
}

Result:- Chain

If the input contains "-" all the times, you can shorten the code as said by Datta, If in any case the input does not contain "-" (e.g. contains only "Chain "), then the above code would throw System.ArgumentOutOfRangeException. Becasue oldString.LastIndexOf returns -1 and oldString.Substring expects argument greater than zero.

Hi
You can use same result in single line:-

string oldString="Chain -99.6";

string newString = oldString.Substring(0,oldString.LastIndexOf("-")).Trim();

Result:- Chain
