C# Winfrom项目,运行程序一段时间后揭示“存储空间不足，无法处理此命令”的报错信息
C# Winfrom项目,运行程序一段时间后提示“存储空间不足，无法处理此命令”的报错信息。
在C# Winfrom项目，有一个form窗体，六个Panel控件(用于放置显示监控视频图像的用户自定义控件)，
还有一个timer计时器控件(设置每隔6分钟调用其它六个监控视频图像放到对应的Panel控件)
目前遇到的问题是，监控点的视频图像有的由于网络好点显示加载视频图像快点，有的由于网络不是太好加载显示视频图像慢点。
在form窗体运行一段时间后，导致这个form窗体的六个Panel控件在轮流显示相应的六个监控视频图像后，提示“存储空间不足，无法处理此命令”的报错信息。
发现在这个时间段内，电脑内存的使用率为40%至50%左右。
请问如何修改下面的代码可以解决此问题？谢谢！

先确认是C盘没空间了，还是内存不足了。32位程序的内存使用有限制的。另外windows的内存使用率显示也有问题，当产生大量内存碎片时，那个使用率根本不准确。

找找这个pl有没有 Close关闭视频的方法。
