跨平臺架構設計
基于GTKSystem.Windows.Forms框架，我們可以實現真正的跨平臺WinForm串口通訊應用：
跨平臺項目配置
首先需要正確配置項目文件以支持跨平臺運行：
<Project Sdk="Microsoft.NET.Sdk.WindowsDesktop"><PropertyGroup><OutputType>WinExe</OutputType><TargetFramework>net8.0</TargetFramework><UseWindowsForms>false</UseWindowsForms><!-- 關鍵：禁用Windows專用的WindowsForms --></PropertyGroup><ItemGroup><!-- 添加GTKSystem.Windows.Forms包 --><PackageReference Include="GTKSystem.Windows.Forms" Version="3.24.24.105" /><PackageReference Include="System.IO.Ports" Version="8.0.0" /></ItemGroup>
</Project>
GtkSharp串口通訊實現
