An image SQL server column type translates to a byte array (byte[])framework type. In your example, the 'temp' variable would have to be declared as byte[]. You could also use the GetBytes(int index) method on your reader. For a more complete type mapping table, look here[^].

The most exciting phrase to hear in science, the one that heralds the most discoveries, is not 'Eureka!' ('I found it!') but 'That's funny...’

if you want to convert it to byte array you have to serialize it. using System.Runtime.Serialization.Formatters.Binary; /*Note i suppose your object is serializable if not add [Serializable] attrubite to your object class*/ BinaryFormatter Serialize=new BinaryFormatter(); MemoryStream stream=new MemoryStream(); byte[]ObjectInBytes=Serialize.Serialize(stream,temp); //to Deserialize stream=new MemoryStream(ObjectInBytes); stream.Seek(0,SeekOrigin.Begin); temp=(TypeOfYourObject) Serialize.Deserialize(stream); marcoryos
