c# wpf和winform有啥区别吗？wpf能使用串口吗

Posted 2023-05-09

wpf中似乎没有serialPort空间，能实现串口功能吗？怎么实现呢？

参考技术A 亲，简单来讲winform能做的，wpf都能做，而且界面做的更好，更炫，wpf编辑程序界面可以向编辑html界面一样，wpf可以使用XAML语言编辑wpf程序的界面，winform则不能使用XAML。至于使用串口，wpf和winform的使用是一样的，因为他们的后台语言用的都是C#

c# winform 报表打印

c#开发winform系统，怎么做报表、表单的打印。
比较简单点的 用户可以自己设置打印表单的样式。

看到过fastreport这个的，但是这个在c#中集成不上。
