static public string ReplaceString(string str, string oldValue, string newValue, StringComparison comparison)
{
StringBuilder sb = new StringBuilder();

int previousIndex = 0;
int index = str.IndexOf(oldValue, comparison);
while (index != -1)
{
sb.Append(str.Substring(previousIndex, index - previousIndex));
sb.Append(newValue);
index += oldValue.Length;

previousIndex = index;
index = str.IndexOf(oldValue, index,
comparison);
}
sb.Append(str.Substring(previousIndex));

return sb.ToString();
}
