C＃白色或黑色不需要的像素出现在图像中

I am new to C#, I am using Visual Studo 2010, I have an image that needs to be displayed on a picturebox. I tried many different methods. All the methods results in some unwanted pixels to appear along with image. I have tried picturebox.Image = Image.FromFile("bird.png");

我是C＃的新手，我使用的是Visual Studo 2010，我有一个需要在图片框上显示的图像。我尝试了很多不同的方法。所有方法都会导致一些不需要的像素与图像一起出现。我试过过picturebox.Image = Image.FromFile（“bird.png”）;

result-> the image is displayed but with the stray white/black pixels at random places.

result->显示图像，但随机位置有杂散的白色/黑色像素。

I also tried creating a bitmap of same size and drawing the image onto the bitmap and then assigning the bitmap to the picture box.Image. Still those unwanted pixels are visible.

我还尝试创建一个相同大小的位图并将图像绘制到位图上，然后将位图分配给图片框。图像。这些不需要的像素仍然可见。

I have tried clearing the picture box image (filling it with white or transparent) and then assigning the image, still same error occurs.

我已经尝试清除图片框图像（用白色或透明填充），然后分配图像，仍然发生相同的错误。

PS: this doesn't happen for all the images only certain images show this behaviour.

PS：对于所有图像都不会发生这种情况，只有某些图像才会显示此行为。

any help would be great

任何帮助都会很棒

Code:

码：

Image org = Bitmap.FromFile("bird.png"); 

Bitmap final = new Bitmap(org.Width,org.Height); 

using (Graphics g = Graphics.FromImage(final))
{
 g.DrawImage(org,0,0,GraphicsUnit.Pixel);

}
picturebox.Image = final;

if i use final.save("picture.png"). The "picuture.png" does not have that wrong pixels, it happens only when i use picture box to display it.

如果我使用final.save（“picture.png”）。 “picuture.png”没有错误的像素，只有当我使用图片框来显示它时才会发生。

Please find the images attached defect orginal

请找到图像附加缺陷原始

PS: its not because of different fileformat (orginal and defect)

PS：它不是因为不同的文件格式（原始和缺陷）
