颤栗效果的GUI使用c#编写的窗体
本文关键字：窗体 GUI 颤栗 使用 | 更新日期: 2023-09-27 18:17:41
对于客户端和服务器系统之间的文件传输，我们在客户端系统上使用c# windows窗体设计了一个GUI。我们添加了许多背景图像和文本框，使GUI令人印象深刻。但是无论何时我们执行客户端代码，GUI都需要几秒钟的时间来加载自己并保持稳定，然后才能从GUI中做出选择。这发生在客户端GUI发出每个请求之后。(就像所有的form元素在短时间内消失并再次出现一样)。请帮帮我。我可以知道原因吗?

尝试在表单构造函数中使用下面的代码。
this.DoubleBuffered = true;
它应该能提高一些性能。Windows窗体不能显示大量相互重叠的图像。
