VS上利用C#實現一個簡單的串口程序記錄

一、背景

　　工作上需要利用串口往下位機寫入數據，VC太老，正好借此機會來熟悉一直很想接觸的VS之C#。

　　感謝Tony托尼哥的串口通信代碼，感謝夢真的C#的技術支持。

二、正文

　　1、項目架構：（以我現有的知識認知來說）

　　　　一共有3個文件：

　　　　a、"Program.cs"保存的是主程序入口。

　　　　b、"Form1.Designer.cs"圖形控件的實現。

　　　　c、"Form1.cs"里面實現的既是用戶邏輯。

　　　　典型代碼結構如下:

最先運行文件"Program.cs"內的主程序                                                          
namespace TB528E4PSE_APP                                                                         
{
    static class Program
    {
        /// <summary>
        /// 應用程序的主入口點。
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new VOUTCTRL());-----------------------|
        }                                                          |                
    }                                                              |        
}                                                                  |                    
然后接着運行"Form1.cs" 文件內的"VOUTCTRL()".                       　　 |

　　至此，代碼跟蹤至此。

 

　　2、更改窗體在屏幕首次出現的位置

　　　　即當APP運行時，窗體會在電腦屏幕的哪個位置彈出。點擊窗體->屬性，

　　　　找到“startposition”，如下圖：

　　　　

　　　　注意以上圖片包含的信息：Text選項，此處則可以表明窗體顯示的信息。

 

　　3，更改窗體顯示的圖標。

　　　　即當APP運行時，窗體在Text旁邊的圖片，點擊窗體->屬性，

　　　　找到“Icon”，如下圖：

　　　　

 

　　4、如何發布程序：

　　　　點擊項目欄“生成”，點擊“發布”選項即可發布程序了，如下圖：
