嗨，大家好。我有关于串行通信的问题 [英] Hi Everyone. I Have Problem About Serial Communication

问题描述

Plz任何人都可以给我发送一个示例程序

我有关于串口plz帮助的问题。我有一个设备发送数据，如＃23 14 35现在我想把它作为textbox1.text = 23 textbox2.text = 14和textbox3.text = 35

plz帮助如何做到这一点。我正在使用visual studio 2010

解决方案

首先查看 SerialPort类 [ ^ ]并确保在开始播放之前可以成功收到整条消息将它拆分 - 相比之下，拆分位是微不足道的。

最糟糕的是，一个简单的string.Split会这样做：

 < span class =code-keyword> string  input =  ＃23 14 35 ; 
  string  [] parts = input.Split（ ＃ .ToArray（））; 

所以请忽略它，直到你让复杂的位工作正常 - 它通常比你想到的更难启动。

Plz anyone can send me a sample program

解决方案

Start by looking at the SerialPort class[^] and make sure you can successfully receive the whole message before you start "playing" with it to split it up - the split bit is trivial in comparison.
At worst, a simple string.Split will do it:

string input = "#23 14 35";
string[] parts = input.Split("# ".ToArray());

So ignore that until you have the complex bit working properly - it's generally harder than you think when you get started.
