C#上位机学习
前言
我的仓库
工程管理器
- 修改生成的EXE图标
.webp)
- 【AssemblyInfo.cs】
- 【Program.cs】
程序的入口，相当于C语言的Main函数
- 【Form1.cs】【常用】
窗体
里面的 Form1 是后台，写代码的地方【常用】
里面的 Form1.Designer.cs 是控件地方，添加一个控件里面自动会添加对应的代码
- 工具栏
- 控件事件
双击事件名称或者双击窗体控件就会生成并跳转到事件
第2讲
- 窗体控件属性
Button 按钮和TextBox 文本框
换行可以
\r\n
ComboBox 组合框和Lable 标签
组合框
DropDownStyle属性 可以设置为DropDownList，这样别人就不能修改内容了只能选
checkBox 多选框和RadioButton 单选框----- 容器：Panel 面板
Checked属性可以用来判断多选框是否被选中状态单选框的话只能有一个处于被选中状态，然后如果需要把单选框分开，互不影响则用到容器—面板
ProgressBar 进度条和PictrueBox 图片框
添加图片的话去资源那添加，需要把图片先复制到工程下文件夹里
GroupBox 组合框，—组件：SerialPort 串口Timer 定时器
- 图形化按钮设计
按下变成另一张图片

- 软件设置保存与汉字显示方法
ini文件读取和写入：
[DllImport("kernel32")] private static extern long WritePrivateProfileString(string section, string key, string val, string filePath); // 系统DLL导入ini写函数 [DllImport("kernel32")] private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath); // 系统DLL导入ini读函数 string FileName = System.AppDomain.CurrentDomain.BaseDirectory + "Backup.ini"; // ini文件名 StringBuilder BackupBuf = new StringBuilder(50); // 存储读出的ini内容变量
WritePrivateProfileString函数用于在 INI 文件中写入配置项。它接受四个参数：
section：表示配置项所属的节（Section）名称；key：表示配置项的名称；val：表示配置项的值；filePath：表示 INI 文件的完整路径和文件名。
GetPrivateProfileString函数用于从 INI 文件中读取配置项的值。它接受六个参数：
section：表示配置项所属的节名称；key：表示配置项的名称；def：表示如果没有找到指定的配置项，则返回的默认值；retVal：表示存储读取到的配置项值的 StringBuilder 对象；size：表示输入的 StringBuilder 对象可容纳的最大字符数；filePath：表示 INI 文件的完整路径和文件名。
FileName：表示 INI 文件的完整路径和文件名，它使用System.AppDomain.CurrentDomain.BaseDirectory获取应用程序根目录的路径，然后加上文件名"Backup.ini"组成完整路径。
BackupBuf：表示存储读取到的 INI 配置项值的 StringBuilder 对象，它的容量为 50 个字符，用于存储较短的字符串类型的配置项值。

其他指令
c#
// 启动多线程延时50ms
System.Threading.Thread.Sleep(50);项目1- STC实战上位机
使用模板，把模板工程下的 文件夹，
suo，slncsproj后缀的名称改为你自定义名称，然后双击 sln文件进入，会报错正常，然后右键移除当前项目，右键选择【添加】，添加【现有项目】，找到工程文件夹下的csproj后缀文件打开即可进入工程后需要双击
Properties，把里面的程序集名称，默认命名空间也改名，然后运行报错，按照报错的行号进行替换即可然后把工程文件夹
bin，obj两个文件夹删除即可会重新生成的，然后关闭工程重新打开即可
