I have a string. I want to find the last instance of "(" and remove it and everything that is behind it.
For example:"skj(ælsu(39)".  I would like to return: "skj(ælsu"
How do I do that

Hi,

This should do the trick:
string val = "skj(ælsu(39)";
int lastPosition = val.LastIndexOf('(');
if (lastPosition>0)
    val = val.Substring(0, lastPosition);

.LastIndexOf finds the last position of the specified character in the given string variable.
You have to check this before using in Substring as if there are no instances of the character in the string, it returns -1 which is an invalid argument to Substring

string x = "skj(ælsu(39)";
if(x.Contains('(')
x=x.Substring(0,x.LastIndexOf('(');
