如何使WPF C＃触摸屏按钮响应 [英] How to make WPF C# touch screen button responsive

问题描述

我正在研究触摸屏应用程序。按下按钮时，它将捕获50张图像。但我的问题是按钮不会释放，直到所有50张图像都来到我的电脑（通过TCP / IP）。然后如何使我的按钮按下并释放以在单独的线程而不是UI线程中运行。



我尝试过：



按钮TouchDown和TouchUp正在发生但是，它需要时间才能发布我的意思是TouchUp

使用< a href =https://msdn.microsoft.com/en-us/library/system.componentmodel.backgroundworker(v=vs.110).aspx> BackgroundWorker [ ^ ]：

或者使用 async 和等待：

你好，对不起，我无法帮你解决问题，但我可能会问你如何为按钮定义TouchDown和TouchUp？

我所做的是：

hello,i am sorry i can't help you with your problem,but may i ask you how to define TouchDown and TouchUp for a button?
what i have done is :

<Button Content="Button" TouchDown="touch_down" HorizontalAlignment="Left" Margin="221,116,0,0" VerticalAlignment="Top" Width="194" Height="75" />

private void touch_down(object sender, TouchEventArgs e)
{
MessageBox.Show("button touched down");
}

它没有回应，怎么了？你能帮帮我吗？

it has no response,what's wrong? Can you help me ?
