Convert picture URL to Bitmap with React & ASP.NET












0














In my application i need to be able to capture image in browser then send it back to the server where it gets processed. currently i have a widget that captures an image and returns a pictureUrl for png image.



I'm looking for a best possible way to send it back to server.



Ideally i want this image put back inside the class that I originally fetch from server, then serialize it back to JSON and send to server.



Lets say for instance I heve the following C# class:



myClassWithImage{
Bitmap myBitmap = null;
///many other properties
}


i serialize it to json and send it to the user.



Then i want react to use the instance of this class, update it with the picture, serialize to json & send back updated version.
On server I just want to recreate the class instance using Newtonsoft.JSON like:



myClassWithImage imgCl = data.SelectToken("myClassWImage").ToObject<myClassWithImage>();


Is this possible at all? Or should i serialize images to base64 string ans send separately?



UPDATE:



I guess what I'm trying to find out if it is possible to serialize/deserialize the object directly into the instance of class without using additional Base64 string properties to it.
If i try to add image Url directly to the myBitmap property I get




Newtonsoft.Json.JsonSerializationException: Newtonsoft.Json.JsonSerializationException: 'Error converting value "data:image/png;base64,....




So should i instead introduce another property to this class to hold the value of the image as string during serialization/deserialization?

  • Yes it is possible, is it not working? Or what errors are you encountering? Personally, I'd use a property that's marked as serializable. Like public bitmap myBitMap {get;set;} type of thing...
