C# 如何将位图添加到ImageList

我在winforms中有以下代码，用于将多个图像组合成一个图像：

private Bitmap CombineImages(params Image[] images)
{
    int width = 0;
    for (int i = 0; i < images.Length; i++)
        width += images[i].Width + 3;

    int height = 0;
    for (int i = 0; i < images.Length; i++)
    {
        if (images[i].Height > height)
            height = images[i].Height;
    }

    int nIndex = 0;
    using (Bitmap fullImage = new Bitmap(width, height))
    {
        using (Graphics g = Graphics.FromImage(fullImage))
        {
            g.Clear(SystemColors.AppWorkspace);
            foreach (Image img in images)
            {
                using (img)
                {
                    if (nIndex == 0)
                    {
                        g.DrawImage(img, new Point(0, 0));
                        nIndex++;
                        width = img.Width;
                    }
                    else
                    {
                        g.DrawImage(img, new Point(width, 0));
                        width += img.Width;
                    }
                }
            }
        }

        return fullImage;
    }

    //img3.Save(finalImage, System.Drawing.Imaging.ImageFormat.Jpeg);
    //img3.Dispose();
    //imageLocation.Image = Image.FromFile(finalImage);
}

谁能告诉我这里出了什么问题吗？？？位图继承自图像，那么这是什么错误？

问题在于，您在using语句中隐式地处理图像对象，因此在添加图像对象时，它们不可用于图像列表

不要处理图像，如有必要，请在完成后处理整个ImageList，它将自行处理其中包含的图像

customerTabCtrl.ImageList.Images.Add("DealingAndBloomberg",     CombineImages(global::Client.CustomerInformation.Properties.Resources.reuters, global::Client.CustomerInformation.Properties.Resources.bloomberg));
