我是新程序员并尝试使用c＃创建程序，点击屏幕上的特定坐标并从屏幕搜索图像，当找到它时点击它。程序工作正常，但30-40分钟后崩溃。弹出崩溃窗口时 - 应用程序中出现未处理的异常....
参数无效

答案 0 :(得分：0)
创建新的位图，图形导致内部GDI +函数调用。所有这些函数最终都会出错，并且错误会转换为.NET异常（遗憾的是没有其他参数名称，信息等）。由于这个原因，一些错误可能真的很难理解。
由于句柄泄漏和内存泄漏（在GDI +的情况下）可能会发生一些问题。例如，创建大量非常大的位图会在非托管空间中分配大量连续的块。 GC不知道内存压力，也不会尝试清理。在让我们说100次调用之后传递宽度和高度足够大可能会注意到内存不足并抱怨抛出ArgumentException的宽度和高度太大。
首先，如果您不需要，请考虑处理位图。 不要忘记处理图形。
如果没有帮助，请告诉我。
