我用c# serialport控件做了一个受并显示从串口受到的数据。但是数据收不到，请大虾们看下，指点指点小弟。程序如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO.Ports;
using System.Net;
using System.Net.Sockets;
using System.IO;
using System.Threading;
using System.Runtime.InteropServices;
namespace livelabel
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
SerialPort sp=new SerialPort();
private void Form1_Load(object sender, EventArgs e)
{
this.serialPort.DataReceived += new System.IO.Ports.SerialDataReceivedEventHandler(this.serialPort_DataReceived);
this.timer1.Tick += new System.EventHandler(this.timer1_Tick);

private void Form1_Load(object sender, EventArgs e)
{
this.serialPort.DataReceived += new System.IO.Ports.SerialDataReceivedEventHandler(this.serialPort_DataReceived);
this.timer1.Tick += new System.EventHandler(this.timer1_Tick);

你这里定义的
SerialPort sp=new SerialPort();
但后面是：
this.serialPort.DataReceived += new System.IO.Ports.SerialDataReceivedEventHandler(this.serialPort_DataReceived);
serialPort在哪里定义的？
那你的sp干什么用的呢？
this.serialPort.DataReceived +=
回1楼，这个serialPort是控件。
