Question

I am developing a windows form application. At one of my form i place a picture box control. Its working fine for majority of time. But sometime it displays red cross rather than displaying actual picture.

我进一步探讨这一问题,并了解到,这种控制处理内部例外情况。因此,一去<代码>Debug->Exceptions,并核对相关的<代码>被抛在箱。然后发现红箱由于以下错误而显示:

A first chance exception of type  System.OutOfMemoryException  occurred in System.Drawing.dll

Additional information: Out of memory.

是否有任何机构建议我如何处理这一例外?

Answer 1

各位评论说,你正在使用<代码>PictureBox上的多种图像。您应“建议”dispose。在应用新形象之前,如:

private void ChangePictureBoxImage(Image image)
{
    pictureBox.Image.Dispose();//dispose the old image.

    pictureBox.Image = image;
}

Answer 2

How much RAM does your target machine have?

你之所以放弃这一例外,是因为为图像分配更多的记忆的呼吁失败。如果你无法增加计算机的记忆量,试图缩小图像尺寸或关闭你运行的任何其他方案。
