Question

我正试图从Toledo 8510比例中获得重量，以便在文本框中显示，然后将其捕获并发送到SQL Server数据库。我已将来自几个来源的代码混合在一起，并且已经获得了在文本框中进行通信和显示输出的比例，但是在比例显示为5.65的情况下，文本框显示为56500000.当比例上没有重量时，它显示0。比例的输出是ASCII，当我使用Code Project或Putty的SerialPortListener时，输出如下所示：＆lt;' 00565 00000.我的解决方案中有代码删除＆lt;'和空格所以我确定最后五个零是ascii字符串的后半部分。

private void UserInitialization()
{
    _spManager = new SerialPortManager();
    SerialSettings mySerialSettings = _spManager.CurrentSerialSettings;
    serialSettingsBindingSource.DataSource = mySerialSettings;
    ComPrtDrpDnBx.DataSource = mySerialSettings.PortNameCollection;
    BaudRtDrpdnBx.DataSource = mySerialSettings.BaudRateCollection;
    DataBtsDrpDnBx.DataSource = mySerialSettings.DataBitsCollection;
    ParityDrpDnBx.DataSource = Enum.GetValues(typeof(System.IO.Ports.Parity));
    StpBtsDrpDnBx.DataSource = Enum.GetValues(typeof(System.IO.Ports.StopBits));

    _spManager.NewSerialDataRecieved += new EventHandler<SerialDataEventArgs>(_spManager_NewSerialDataRecieved);
    //this.FormClosing += new FormClosingEventHandler(WeighInFrm_FormClosing);
}

private void WeighInForm_FormClosing(object sender, FormClosingEventArgs e)
{
    _spManager.Dispose();
}

void _spManager_NewSerialDataRecieved(object sender, SerialDataEventArgs e)
{
    if (this.InvokeRequired)
    {
        // Using this.Invoke causes deadlock when closing serial port, and BeginInvoke is good practice anyway.
        this.BeginInvoke(new EventHandler<SerialDataEventArgs>(_spManager_NewSerialDataRecieved), new object[] { sender, e });
        return;
    }

    int maxTextLength = 9; // maximum text length in text box
    if (CapWeghtTxtBx.TextLength > maxTextLength)
        CapWeghtTxtBx.Text = CapWeghtTxtBx.Text.Remove(0, CapWeghtTxtBx.TextLength - maxTextLength);
    // This application is connected to a Scale sending ASCII characters, so data is converted to text
    string str = Encoding.ASCII.GetString(e.Data);
    string newString = Regex.Replace(str, "[^.0-9]", ""); //Remove the Caret symbol and any spaces
    CapWeghtTxtBx.AppendText(newString);
    CapWeghtTxtBx.Select(CapWeghtTxtBx.TextLength, 0);
    CapWeghtTxtBx.ScrollToCaret();
    CapWeghtTxtBx.Text = string.Format("{0:0}", double.Parse(CapWeghtTxtBx.Text)); //formats the text

    }


    private void CapWeghtTxtBx_TextChanged(object sender, EventArgs e)            
    {

    }
