无法从串口获取正确的数据

问题描述

我正在开发用于读取串行端口数据的窗口应用程序.

这是我读取串口的代码:

I am develop window application for reading serial port data.

Here is my code for reading serial port:

void comPort_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
    try
    {
        if (comPort.IsOpen == true)//comPort is serial port which i use in my project
        {
            bytes = comPort.BytesToRead;
            byte[] comBuffer = new byte[bytes];
            comPort.Read(comBuffer, 0, bytes);
        }
    }
    catch (Exception ex)
    {
    }
}

我的问题是当我连接两台计算机并将数据从一台计算机发送到我的软件时，我没有收到完整的数据.但是当我放置断点和此事件并检查然后它显示完整数据并且还显示完整数据但没有断点时没有显示完整的数据意味着丢失了许多数据.
请解决此问题.

推荐答案

报价:

基于编码，读取SerialPort对象的流和输入缓冲区中所有立即可用的字节.

Reads all immediately available bytes, based on the encoding, in both the stream and the input buffer of the SerialPort object.
