跨平台架构设计
基于GTKSystem.Windows.Forms框架，我们可以实现真正的跨平台WinForm串口通讯应用：
跨平台项目配置
首先需要正确配置项目文件以支持跨平台运行：
<Project Sdk="Microsoft.NET.Sdk.WindowsDesktop"><PropertyGroup><OutputType>WinExe</OutputType><TargetFramework>net8.0</TargetFramework><UseWindowsForms>false</UseWindowsForms><!-- 关键：禁用Windows专用的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串口通讯实现

using System.IO.Ports;
using System.Text;
using System.Threading;/// <summary>

跨平台部署配置
Linux系统配置
# 安装GTK运行时环境
sudo apt-get update
sudo apt-get install gtk-sharp3-dev# 设置串口权限
sudo usermod -a -G dialout $USER
sudo chmod 666 /dev/ttyUSB*
sudo chmod 666 /dev/ttyACM*# 运行应用程序
dotnet run
macOS系统配置
# 使用Homebrew安装GTK
brew install gtk+3# 设置串口权限
sudo dseditgroup -o edit -a $USER -t user wheel# 运行应用程序
dotnet run
