I have a table with a few VarBinary columns. I use code similar to the following code, to write the contents of a dataset (that was populated with data from the table menthioned earlier) to an XML file:

this.oDS.WriteXml(sMyFile, XmlWriteMode.WriteSchema);

Now I want to read the data from the XML file and I use code similar to this:

DataSet oDS = new DataSet("ds");
oDS.ReadXml(sMyFile);
byte[] ba = (byte[]) oDS.Tables[0].Rows[0].ItemArray[6];

Is this the best way to get the binary data out as a byte array (byte[])?

Is there any thing that I should be aware of when putting binary data into a dataset?
