How to Efficiently Read and Process Data from a USB Serial Scale Using C#?

This code is specially designed for USB serial devices and provides an efficient solution for reading scale data:

private void PortOnDataReceived(object sender, SerialDataReceivedEventArgs e)
{
    // 持续读取串口数据
    while (_port.BytesToRead > 0)
    {
        // 读取传入数据
        string rawData = _port.ReadExisting();

        // 重新格式化数据以与SendKeys()兼容
        string reformattedData = DefaultFormatter.Reformat(rawData);

        try
        {
            // 将重新格式化的数据发送到指定的应用程序
            SendKeys.SendWait(reformattedData);
        }
        catch (Exception ex)
        {
            // 处理向不兼容应用程序发送数据时可能发生的异常
        }
    }
}

For USB serial devices, this code provides a more robust method of reading scale data:

private void PortOnDataReceived(object sender, SerialDataReceivedEventArgs e)
{
    // 持续读取串口数据
    while (_port.BytesToRead > 0)
    {
        // 读取传入数据
        string rawData = _port.ReadExisting();

        // 根据需要处理数据（例如，过滤、解析等）
        string processedData = ProcessRawData(rawData);

        // 处理后，将数据发送到所需的目标位置（例如，RichTextBox、控制台等）
        richTextBoxReceivedData.AppendText(processedData);
    }
}
