Solution 1

Take off the ToString method call.
If person.myPicture is an Image, you can use it directly.

i removed the ToString and got this error message
Cannot implicitly convert type 'object' to 'System.Drawing.Image'. An explicit conversion exists (are you missing a cast?)

Then you need to check what you have declared (and assigned to) the person.myPicture property as.
If it is an Image, you wouldn't get the error, so you need to know what it actually is...

i noticed in the class i used picture = dr["picture"].ToString();
i removed the ToString and got an error msg
Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?)

what should i do pls

dr["picture"] implies you are getting this from a database, and that it had a ToString call on it implies that the DB stores the path to the file (or a partial path at least). You need to load the Image from the file:
Image myImage = Image.FromFile((string) dr["picture"]);
I could be wrong - but it's a good guess based on current information!
