C#串口通信
C#串口通信中当我点选HexSend发送的时候将输入框数据转化为十六进制,取消点选将数据转化过来,点选HexView将接收框数据转化为十六进制,取消点选将数据转化过来
代码如下,请大侠帮忙完善,不胜感激

试试吧,有问题再说

您好,我现在的问题还是没解决,例如:我在输入框输入11,当我点击的时候将11转化为十六进制即31 31,当我取消点选的时候,将31 31转化为11,你QQ多少,方便告诉我的话,就说一下,我的350674330

你的意思就是说点了以后能将11转换为31 31,但是去掉以后不能把31 31转换成11对吧?我想这个工作应该你自己做了,你说对吧?

程序代码:
String res=null;
        private void ckbxSend_CheckedChanged(object sender, EventArgs e)
        {
           if (ckbxView.Checked)
            {           
            byte [] array=new byte[txtSend.Text.Length];
            array = Encoding.ASCII.GetBytes(txtSend.Text.Trim());
            string str = ByteArrayToHexString(array);
            res=txtSend.Text;
            txtSend.Text = str;
            }
           else
           txtSend.Text=res;
        }

        private string ByteArrayToHexString(byte[] data)
        {
            StringBuilder sb = new StringBuilder(data.Length * 3);
            foreach (byte b in data)
            {
                sb.Append(Convert.ToString(b, 16).PadLeft(2, '0'));
                sb.Append(" ");
            }
            return sb.ToString().ToUpper();
        }

弄个小技巧,现在应该没问题了
