dynamic image control
I am getting dynamic image in form of byte array. and i want to show that in webpage, preferably ImageControl
I am aware of method of creating http handler and getting image stream. but I cant do that here as logic for same is performed somewhere e开发者_如何转开发lse.
Could not get any suitable way to do this.
Thank you in advance.
You can still convert your byte array to a stream in your handler and send the bytes as normal. Here's a good post on how to do that: Creating a byte array from a stream
Finally I took middle approach.
I am having image object in code behind. For shwoing that in main web page.
I am adding that object in Cache with one random key (in my case GUID). Then I am generating URL such as ~/GetImage.ashx?id=[GUID]
When this URL is accessed an image from cache will be stored.
Note:
- I am adding image to cache with self expiration set to absolute 2 mins. to ensure cache will be empty without manual intervention and there is enough time for other processing to happen.
- Used Cache over Session for same reason mentioned in point 2, where i may have to manually remove it.
Of course I am still open for better solution.
