求助大神：串口接收文本时，以十六进制接收时数据正常，接收以中文显示时偶尔会出现乱码，一直搞不定，请高手给点意见。

代码如下

        private void btnComOpen_Click(object sender, EventArgs e)

        {

            if (btnComOpen.Tag.ToString() == "0")

            {

                ComDevice.PortName = cbbComList.SelectedItem.ToString();

                ComDevice.BaudRate = 115200;

                ComDevice.Parity = (Parity)0;

                ComDevice.DataBits = 8;

                ComDevice.StopBits = (StopBits)1;

                try

                {

                    ComDevice.Open();

                }

                catch (Exception ex)

                {

                    MessageBox.Show(ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);

                    return;

                }

                btnComOpen.Text = "关 闭";

                btnComOpen.Tag = "1";

                picComStatus.Image = Properties.Resources.green;

                ComDevice.DataReceived += new SerialDataReceivedEventHandler(ComDevice_DataReceived);

            }

            else

            {

                try

                {

                    ComDevice.Close();

                }

                catch (Exception ex)

                {

                    MessageBox.Show(ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);

                }

                btnComOpen.Text = "打 开";

                btnComOpen.Tag = "0";

                picComStatus.Image = Properties.Resources.red;

            }

        }



        #region 接收数据



        private void ComDevice_DataReceived(object sender, SerialDataReceivedEventArgs e)

        {

            byte[] ReDatas = new byte[ComDevice.BytesToRead];//返回命令包

            ComDevice.Read(ReDatas, 0, ReDatas.Length);//读取数据

            UpdateRecevie(System.Text.Encoding.Default.GetString(ReDatas));

        }
