Why use regex?

C#

// I would personally make this an extension method
public static string ReplaceOccurrence(this string str, string target, string replacement, int count)
{
    int pos = -1;
    int counted = 0;
    string result = "";
    do
    {
        pos = (pos >= 0) ? str.IndexOf(target, pos+1) : pos = str.IndexOf(target);
        if (pos >= 0)
        {
            counted++;    
        }	
    } while (pos >= 0 && counted != count);
    if (pos >= 0)
    {
        result = str.Insert(pos, replacement).Remove(pos + replacement.Length, target.Length);
    }
    return result;
}

Usage:

C#

string x = "(hello) (world)";
string y = "";

y = ReplaceOccurrence(x, "(", "^", 1); // result = "^hello) (world)"
y = ReplaceOccurrence(x, "(", "^", 2); // result = "(hello) ^world)"
y = ReplaceOccurrence(x, ")", "^", 2); // result = "(hello) (world^"
y = ReplaceOccurrence(x, "(", "ZZZZ", 2); // result = "(hello) ZZZZworld)"
y = ReplaceOccurrence(x, ")", "", 2); // result = "(hello) (world"
