Hello im a new programmer and i have a project written in C#. here's my code:

 else if (!Regex.IsMatch(textBox1.Text, @"^[" "][!][@][#][$]['^'][&][*][()][,][>][.][,][?][/]"))
            {
                MessageBox.Show("Invalid name!\nthe name can't have these Regular Expressions:\n !@#$%^&*(),.");
