Get Byte Array using Enterprise Library

It took me a while to figure this out so I thought I would post the solution here. I needed to get a blob out of the database and assign it to a byte[] in my object

Solution

//initialise the byte[] and get its size
byte[] byteArray = new byte[(dr.GetBytes(dr.GetOrdinal("File"), 0, null, 0, int.MaxValue))];
//Assign bytes to byte array
dr.GetBytes(dr.GetOrdinal("File"), 0, byteArray, 0, byteArray.Length);
//Assign Value
file.FileByte = byteArray;

Enjoy
