Does any one know of an example on how to store an image in a SQL Server CE database?
What data type should the column be? (I am guessing binary.)
I use Linq-To-Datasets. Is it possible using that to put the image into the database and pull it out again later?
Thanks for any advice.
Here is how I did it:
MemoryStream stream = new MemoryStream();
myBitmapImage.Save(stream, ImageFormat.Png);
myInsertLinqToDataSetRow.IMAGE_COLUMN = stream.ToArray();
To load it back out again I did this:
MemoryStream stream = new MemoryStream(myLinqToDataSetRow.IMAGE_COLUMN);
myBitmapImage.SignatureImage = new Bitmap(stream);
I found a page on MSDN that said that the Image column type is going away and that you should use varbinary(MAX). Max is not supported on SQL Server CE so I did varbinary(8000).
LATER NOTE: while varbinary(max) is not supported on SQL Server CE. Varbinary(8000) is not big enough for many images. I did end up using the Image type even though it is planned to be deprecated. Once ms offers a resonable alternitive on the mobile platform I will consider switching.
