i've looked @ how can create instance of derived class instance of base class , include private fields? , create instance of derived class base class either i'm not getting it, or they're not quite i'm looking for. i have class, derived another, implementing particular interface: public class derivedclass : baseclass, iderivedclass baseclass implements ibaseclass , iderivedclass inherits ibaseclass . sometimes, want able initialize derived class, when have instance of base class. create constructor copies each of properties instance of base properties of instance of derived class, there way? along lines of: baseclass bc = new baseclass(); derivedclass dc = new derivedclass() : bc; is do-able? if not, why not? i'm prepared accept might not possible, if so, i'd quite interested if can explain why. no, not possible. you have create object since has have characteristics of second object. can't copy 1 another. might object invalid ...

c# - MVC Stream Picture rotated -

i want use rotated image in mvc application. purpose worte controller returns rotated image, cant working. this command: public actionresult picturestreamrotate(string filename) { image image = image.fromfile(filename); image.rotateflip(rotatefliptype.rotate90flipnone); memorystream stream = new memorystream(); image.save(stream, imageformat.jpeg); return file(stream, "image/jpeg"); } the image streamed invalid. dies have idea. input picture jpg file. btw. if remove thw line image.rotateflip wont work. this happens because stream's position after written data. toarray() get's in stream start. alternatively, set position 0 or seek start of image data. try in linqpad: var x = new memorystream(); x.writebyte(123); x.readbyte().dump(); it gives -1 result... then x.position=0; and 123 back. btw, toarray() copies data, not want, guess.
