c# - Convert a byte[] to Image without using a MemoryStream -

i having problem exporting sql images files. first initialize list. myrecord class graphicname, , graphic properties. when try go through list , save myrecord.graphic disk first chance exception of type 'system.objectdisposedexception'. realize because when converted bytes database image used using statement memorystream. can not use using statement , works, worried memory usage / memory leaks on 6,000 records. there way convert bytes image or there better design this?

... prior code using (sqldatareader reader = sqlcommand.executereader()) {     while (reader.read())     {         myrecord record = new myrecord();         record.graphicid = reader["graphic_id"].tostring();         record.graphic = !reader.isdbnull(reader.getordinal("image")) ? getimage((byte[])reader["image"]) : null;         records.add(record);     } ... more code  private image getimage(byte[] rawimage) {     using (system.io.memorystream ms = new system.io.memorystream(rawimage))     {         image image = image.fromstream(ms);         return image;     } } 

you shouldn't use using statement stream passed image.fromstream, image class responsible stream on. documentation:

you must keep stream open lifetime of image.

just change code to:

private image getimage(byte[] rawimage) {     var stream = new memorystream(rawimage);     return image.fromstream(stream); } 

... make sure dispose of image objects later. dispose of stream, allowing memory garbage collected. there shouldn't memory leaks - need work out whether can load 6000 images memory @ time anyway.

(if don't dispose of image objects, they're finalized anyway @ point - better dispose of them deterministically.)
