C#接收，跪求各位大哥大姐帮忙啊!!
VS2008，C#界面就一个TextBox，要求用serial类事件和委托发送和接收，接收串口数据存入一字符数组并转换成字符串TextBox显示，项目中急要。自己看了一天C#事件和委托都没看懂，！！！！！！哪位好心人帮我写下，合适晚上就给分！！谢谢 --------------------编程问答--------------------

2楼代码挺长，好晕。。。

这是一个委托 通用类
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
namespace test
{
public class FormControl
{
delegate void UpdateTextSafe(Control c,string text);
delegate void UpdateEnableSafe(Control c, bool bEnable);
delegate string GetTextSafe(Control c);
delegate void ChageTextColorSafe(Control c, System.Drawing.Color str); //改变颜色
delegate void ChageImageSafe(Control c, System.Drawing.Image str); //改变图片
delegate void UpdateDataSafe(Control c, string str1, string str2, string str3, string str4, string str5, string str6);//列表显示
public FormControl()
{
}
public void SetPicture(Control obj, System.Drawing.Image str)
{
ChageImageSafe slt = new ChageImageSafe(SetPicture);
Control c = obj;
if (c.InvokeRequired)
{
c.BeginInvoke(slt, new object[] { c, str });
}
else
{
c.BackgroundImage = str;
}
}
public void SetColor(Control obj, System.Drawing.Color str)
{
ChageTextColorSafe slt = new ChageTextColorSafe(SetColor);
Control c = obj;
if (c.InvokeRequired)
{
c.BeginInvoke(slt, new object[] { c, str });
}
else
{
c.ForeColor = str;
}
}
public void SetText(Control obj, string str)
{
UpdateTextSafe slt = new UpdateTextSafe(SetText);
Control c = obj;
if (c.InvokeRequired)
{
c.BeginInvoke(slt, new object[] {c, str });
}
else
{
c.Text = str;
}
}
public void SetButton(Control obj, bool bEnable)
{
UpdateEnableSafe slt = new UpdateEnableSafe(SetButton);
Control c = obj;
if (c.InvokeRequired)
{
c.BeginInvoke(slt, new object[] {c, bEnable });
}
else
{
c.Enabled = bEnable;
}
}
public string GetText(Control obj)
{
GetTextSafe slt = new GetTextSafe(GetText);
Control c = obj;
if (c.InvokeRequired)
{
c.BeginInvoke(slt, new object[] { c });
}
else
{
return c.Text;
}
return c.Text;
}
}
}
调用的时候可以这样
FormControl fc=new FormControl();
fc.SetText(label1,"测试");
串口通信
sp.PortName = DutouCom;
sp.BaudRate = Convert.ToInt32(DutouBaudRate);
sp.ReadTimeout = 5000;//5秒后时间过期
sp.DataReceived += new SerialDataReceivedEventHandler(Sp_DataReceived);
try
{
sp.Open();
}
catch()
{

帮你顶起！ --------------------编程问答-------------------- 关注中 --------------------编程问答-------------------- 关注中。 --------------------编程问答-------------------- 我有这儿有vb.net写的 demo
给我你的Email 我发给你。 --------------------编程问答-------------------- 关注中。。 --------------------编程问答-------------------- 楼主大意应该是这样的：
1、用 System.IO.Ports.SerialPort 接收数据，并显示在TextBox中
2、必须用事件接收，在事件中更新TextBox的内容
而 System.IO.Ports.SerialPort 的事件是异步的，不能直接在事件中对TextBox进行赋值，所以用到委托。
理解没有错的话，那么问题就简单了，楼主你先别管什么委托，程序该怎么写就怎么写，最后把对TextBox赋值的那句话改一下即可。
只要写一个更新TextBox的委托：
//用于显示文本的委托类型
private delegate void SetTextBoxtxt(TextBox tb,String txt);
//委托的函数用于更新文本框内容
private void settextboxtxt(TextBox tb,String txt)
{
tb.Text=txt;
}
然后在你的函数中更新TextBox内容部分，把"textBox1.Text=XXX;"改成下面几句（假定XXX是你收到的字符串）：
SetTextBoxtxt stxt = new SetTextBoxtxt(settextboxtxt);
Invoke(stxt, new object[] { TextBox1, XXXX });
--------------------编程问答-------------------- 帮顶，学习中，委托这东西，看了我好长时间，还是不太明白，呵呵 --------------------编程问答--------------------
委托这东西，就是指向函数的指针。 --------------------编程问答-------------------- 串口调试工具，发送字符串，程序中接受啊 --------------------编程问答-------------------- 占座学习 --------------------编程问答-------------------- 友情接分! --------------------编程问答-------------------- 你没在服务端挂起listen吧。。。
我记得是不是和你说过了？
你没挂listent
send的时候，肯定接受不了。
补充：.NET技术 , C#
