窗体

效果：串口和网口旁边的是panel当客户端或者服务器发送消息的时候会闪烁，下面的的textbox当接收到接受或者发送的数据会增加数量，心跳机制单选框可以开关，可设置心跳间隔和内容，重置按钮重置串口数据，保存按钮是保存串口数据(groupBox:提示框，panel,面板，comboBox下拉框，radioButton,单选框，checkBox,多选框)

ini文件：

在路径Debug创建File，file里创建Setting.ini

读取配置文件:

string dirPath = Path.Combine(Application.StartupPath, "File");

string filePath = Path.Combine(dirPath, "Setting.ini");

Ini = new IniHelper(filePath);
