Question

我不知道问题到底是什么。我可以加载小的jpeg文件，但是当我尝试加载tga文件时，我得到了异常。我尝试调整图像大小，但这也没有帮助。

public static System.Drawing.Image resizeImage(System.Drawing.Image imgToResize, Size size)
{
    return (System.Drawing.Image)(new Bitmap(imgToResize, size));
}

private void imageToolStripMenuItem4_Click(object sender, EventArgs e)
{

    if (tabControl1.TabCount == 0)
    {
        MessageBox.Show("Please add a form first");
        return;
    }

    OpenFileDialog openFileDialog1 = new OpenFileDialog();
    openFileDialog1.Filter = "TGA (*.tga)|*.tga|JPEG (*.jpg)|*.jpg|BITMAP FILES (*.bmp)|*.bmp|PNG (*.png)|*.png";
    openFileDialog1.FilterIndex = 1;

    if (System.Windows.Forms.DialogResult.OK == openFileDialog1.ShowDialog())
    {
        BckImageRadioBtnGrp bimrbg=new BckImageRadioBtnGrp();
        bimrbg.ShowDialog();

        string result = bimrbg.getResult();

        if (result != null)
        {
            switch (result)
            {
                case "Center"   : (GetDesignSurface(tabControl1.SelectedTab) as System.Windows.Forms.UserControl).BackgroundImageLayout = ImageLayout.Center;   break;
                case "Zoom"     : (GetDesignSurface(tabControl1.SelectedTab) as System.Windows.Forms.UserControl).BackgroundImageLayout = ImageLayout.Zoom;     break;
                case "Tile"     : (GetDesignSurface(tabControl1.SelectedTab) as System.Windows.Forms.UserControl).BackgroundImageLayout = ImageLayout.Tile;     break;
                case "Stretch"  : (GetDesignSurface(tabControl1.SelectedTab) as System.Windows.Forms.UserControl).BackgroundImageLayout = ImageLayout.Stretch;  break;
                case "None"     : (GetDesignSurface(tabControl1.SelectedTab) as System.Windows.Forms.UserControl).BackgroundImageLayout = ImageLayout.None;     break;
            }
        }

         //getting exception here. I set a small resizing size just for testing if it works. it doesn't
        System.Drawing.Image img = resizeImage(System.Drawing.Image.FromFile(openFileDialog1.FileName), new Size(100, 100));

        (GetDesignSurface(tabControl1.SelectedTab) as System.Windows.Forms.UserControl).BackgroundImage = img;
        }
}
}

}

所以，问题是，如何加载图像？

Answer 1

OutOfMemoryException是System.Drawing.Image.FromFile拒绝无法加载文件的典型方式，例如损坏的文件或不支持的像素格式等。例外很混乱，可能与GDI +有关。文件的大小根本不重要。

请参阅此MSDN页面上的例外部分：http://msdn.microsoft.com/en-us/library/stf701f5.aspx

如果单个图像出现问题，您可以尝试使用更宽松的图形设计工具重新保存图像（如果可以打开它！），或者您可以尝试使用其他图片处理库而不是本机.Net方法，它不依赖于GDI +。

AFAIK，大多数情况下发生异常时没有直接的简单解决方案来强制＆＃34;强迫＆＃34;加载图片。

在c＃中加载1 mb的tga文件时出现OutOfMemoryException
