SharpDx绘制形式而无需使用Renderloop将其无限实现

Question

嗨，就像标题所说的那样，我试图为一个项目做一个图像查看器(在Windows Image Viewer的类型中有点(。我看到了很多代码将它们的Renderform展示到Renderloop中，但是我不喜欢此解决方案，因为我不想在Renderloop中无限地刷新图像。我只想在需要重新绘制时(以示例为例。(问题是，问题是，现在我尝试使用renderloop.show((，但它不在屏幕上，毕竟要关闭代码已执行...

我的目标是绘制((在不输入Renderloop的情况下绘制表单。我只想刷新图像，而不是不断刷新它。

实际上可以在不使用无限环路的情况下将图像显示在窗口形式中。添加缩放或调整大小之类的动作在您的表单中并执行操作(这样重新绘制了您的图像(。

当然，如果您正在制作视频游戏，那不是最好的解决方案，因为您想要不断的图形渲染。但是，对于图像查看器而言，只能将所有内容绘制到Windows表单上并在ActionEvents上进行更新。
