共享项目中使用Wpf和Winform——c# CAD二次开发

news 来源：原创 2025/6/15 5:49:46

在共享项目中手动编码创建 UI（如通过代码逐个初始化控件）的优缺点可简单汇总如下：

优点：

  • 代码可控性强：直接操作控件属性和布局，避免设计器生成的冗余代码，便于理解和调试。
  • 灵活性高：适合复杂交互逻辑或动态布局，可在运行时灵活调整 UI 元素。
  • 跨平台适配性好：若项目涉及跨平台（如通过代码适配不同框架），手动编码更易统一逻辑。

缺点：

  • 开发效率低：需手动编写大量控件初始化代码，比可视化设计器耗时更多。
  • 维护成本高：UI 变更时需修改多处代码，易因疏忽导致错误（如控件位置、事件绑定）。
  • 可视化预览困难：无法通过设计器实时查看布局效果，需运行程序才能验证。
  • 团队协作易冲突：多人修改同一 UI 代码时，易因布局逻辑重叠导致合并冲突。

项目结构如下：

wpf类：

using Button = System.Windows.Controls.Button;
using TextBox = System.Windows.Controls.TextBox;
using UserControl = System.Windows.Controls.UserControl;

}
