how to Byte[] ->image?

[Bimawen]

Hi,

I tried to grab an image from the internet, forexample from
www.microsoft.com/image1.jpg, by using WinHttp. but WinHttp.ResponseBody is
a byte[], so when I tried to show them back to my browser by using:

Response.BinaryWrite(objWinHttp.ResponseBody)

it shows like a mess of letters. So my question is how can I show it up
correctly? A further question is

can I save it as an image file?

Thanks!

Set the content-type of the response to the mime type for the image.

Example:

Response.ContentType = "image/jpeg";

A further question is

Yes. Just write the bytes to a file.

Example:

File.WriteAllBytes("c:\test.jpg", objWinHttp.ResponseBody);

Thank you for your instruction. I tried your sample code, but I still cannot
see the image. This time, the page did not show up the mess of codes(or
letter), instead of a broken image icon with image size 0x0.

And it could be saved into a jpg file, but no program can open it.

Any idea?

Thank you very much!

Make sure that there is nothing more sent to the browser than the image
data, for example markup code that is rendered to the browser.
