Question

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：

任何想法为什么我会得到这个例外以及如何解决它？

看起来这是您的图片文件的格式问题。请参阅FromFile method例外情况。

为什么我会得到这个Out of Memory Exception？
