FileInfo fInfo = new FileInfo(sPath); long numBytes = fInfo.Length; //Open FileStream to read file FileStream fStream = new FileStream(sPath, FileMode.Open, FileAccess.Read); //Use BinaryReader to read file stream into byte array. BinaryReader br = new BinaryReader(fStream); //When you use BinaryReader, you need to supply number of bytes to read from file. //In this case we want to read entire file. So supplying total number of bytes. data = br.ReadBytes((int)numBytes); return data; } </code></pre> <p>and insert it into database.</p> <p>i retrive the image via this code:</p> <pre><code>public static Image CreateImage(byte[] imageData) { Image image=null; if(imageData !=null) { using (MemoryStream inStream = new MemoryStream()) { inStream.Write(imageData, 0, imageData.Length); image = Bitmap.FromStream(inStream); } } return image; } </code></pre> <p>and assign the pictureBox Image to CreateImage return value.</p> <p>until here every thing is fine but when i want to store pictureBox image on the disk</p> <pre><code> Bpicture.Image.Save(@"pic1.jpeg", ImageFormat.Jpeg); </code></pre> <p>this error occurs :</p> <pre><code>An unhandled exception of type 'System.Runtime.InteropServices.ExternalException' occurred in System.Drawing.dll Additional information: A generic error occurred in GDI+. </code></pre> <p>also this error doesn't happen when i load image from disk instead of database</p>
