C# 将字符串转化为字节数组和将字符串转化为char数组

 string str = "abchdjdlg";
            byte[] byte1 = Encoding.UTF8.GetBytes(str);//将字符串转化为字节数组
            string str2 = Encoding.UTF8.GetString(byte1, 0, byte1.Length);//将字节数组转换为字符串
           
            
            string a = "abchd";
            char[] chs = a.ToCharArray(); //将字符串转化为char数组
            string str3 = new string(chs); //将char数组转换为字符串
