Answer 1

Modify your CustomFormat method like this:

private static string CustomFormat(string input)
{
    input = input.Replace(@"\", @"\\"); 
    input = input.Replace(@"%", @"\%");
    input = input.Replace(@"[", @"\[");
    input = input.Replace(@"]", @"\]");
    input = input.Replace(@"_", @"\_");
    return input;
}
