The docs say that the value you're passing is is either not a valid image format or null. So what type of image is image? Why are you typecasting it to a byte array earlier in the code?
Hello @Michael Taylor
the type of image is Object
This is the head of the method
That is just a placeholder type. You need to actually look at what is being passed in. It must be a byte array that contains a valid image otherwise you cannot convert it.
//Will fail
TakePhoto(10);
//Will work
TakePhoto(Image.FromFIle(""));
//Will only work if array came from an image
TakePhoto(imageArray);
You can do typechecking to some degree but there is no way to confirm a byte[] is an image without trying to convert.
if (image is byte[] arr)
//try to convert to image
Okay So if the image is byte[] arr how can i convert it to system.drawing.Image ?
Again, an arbitrary array cannot be converted to an Image. There is insufficient information. However assuming that you converted an existing image to a byte[] and are then passing a (fully valid image byte array) to this code then you can go the other way using FromStream.
//Cannot use a code block because forum has bug...
using (var stream = new MemoryStream(image as byte[])) {
var actualImage = Image.FromStream(stream);
}
If the byte array is not a valid image format then this will fail. There is nothing you can do about that, it must be a valid image.
