i want to return Text_view class when the user enter y or alternatively return to start point of the the program when the user hit y

(我想在用户输入y时返回Text_view类，或者在用户按下y时返回程序的起点)

CS0029 Cannot implicitly convert type 'opreation_sign.Text_view'

(CS0029无法隐式转换类型“ opreation_sign.Text_view”)

class error { 
    public string cod()
    {
        var charr = Console.ReadLine();
        if(charr == "y")
        {
            var ret = new Text_view();
            return ret;
        }
        if (charr == "n")
        {
            Environment.Exit(0);
        }
        return null;
    }
