Using WPF Imaging classes - Getting image dimensions without reading the entire file
This should do it:
var bitmapFrame = BitmapFrame.Create(new Uri(@"C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\Winter.jpg"), BitmapCreateOptions.DelayCreation, BitmapCacheOption.None);var width = bitmapFrame.PixelWidth;var height = bitmapFrame.PixelHeight;
Following Sir Juice's recommendation, here is some alternative code that avoids locking the image file:
using (var stream = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.Read)){ var bitmapFrame = BitmapFrame.Create(stream, BitmapCreateOptions.DelayCreation, BitmapCacheOption.None); var width = bitmapFrame.PixelWidth; var height = bitmapFrame.PixelHeight;}
