问题描述
Hello亲爱的程序员，
我正在试图通过这个代码来连接我的kinect。它自己的代码不会消除任何错误，
但是当我连接kinect时它会给我"unhandeled exception"。在行
（int stride = width * format.BitsPerPixel / 8;）
我搜索了很多，但我不明白如何解决它。能帮助我吗。
谢谢，
Houssam

Hello dear Programmers,
i am trzing to connect my kinect through out this code belwo. The code by it self doesnot dive any errors,
but when I am connecting the kinect it gives me then "unhandeled exception" on the line
(int stride = width * format.BitsPerPixel / 8;)
I have searched a lot, but I didn't understand how to fix it. can you please help me.
Thanks,
Houssam
