Hi,

Im trying to compile an exercise, that reads a string backward which I would on fixing this error extend it to ceasar's cipher.
my code is here:

Code:
private void button1_Click(object sender, EventArgs e)
        {
            string stg2c="";
            string cstg="" ;
            char[] characterarray;
            stg2c = textBox1.Text;
            characterarray=stg2c.ToCharArray;

            for (int i = characterarray.Length - 1; i >= 0; i--)           
            textBox2.Text += (characterarray[i]);
        }
The error message is this:Cannot assign to 'ToCharArray' because it is a 'method group'

Any help pls?
