C# - Read Exif metadata for Date Taken

I am in the process of writing a C# utility to move my photo collection to various locations based on either the date taken, date created or date modified.  Originally, I used the Image.FromFile method, then GetPropertyItem to pull DateTakenValue property.  While this did work, it was terribly inefficient, especially when dealing with thousands of files.  Alternatively, the method below is many times faster and significantly more efficient.

For example, a 757kb jpg file using Image.FromFile took 67ms to get the date taken property.  Using the method below, this was reduced to 4ms.

Remember to add a reference to both PresentationCore and WindowsBase.

 using System.Windows;  
 using System.Windows.Media.Imaging;

  
 private DateTime getDateTaken(string inFullPath)  
     {  
       DateTime returnDateTime = DateTime.MinValue;  
       try  
       {  
         FileStream picStream = new FileStream(inFullPath, FileMode.Open, FileAccess.Read, FileShare.Read);  
         BitmapSource bitSource = BitmapFrame.Create(picStream);  
         picStream.Close();   
         BitmapMetadata metaData = (BitmapMetadata)bitSource.Metadata;          
         returnDateTime = DateTime.Parse(metaData.DateTaken);  
       }  
       catch  
       {  
         //do nothing  
       }  
       return returnDateTime;  
     }
