【问题描述】：
我有这个 C# 段代码：
string fileName = Path.GetTempPath() + "\\temp.bmp";
image.Save(fileName);
bmp = (Bitmap)Image.FromFile(fileName);
在这一行： bmp = (Bitmap)Image.FromFile(fileName);
我得到了这个例外：
**System.OutOfMemoryException was unhandled
Message=Out of memory.

内部异常： **
知道为什么会出现此异常以及如何修复它？
【问题讨论】：
-
temp.bmp 的大小是多少？
-
bmp 是我创建的一个空对象：Bitmap bmp;
