xmlDoc.DataSet.Tables.Rows.Add(row) ?

I am debugging some legacy code:

 row["pix"] = (byte[])reader.GetValue(0);

The problem is that the element "pix" does not occur within
the .xsd document. I need to insert the values of reader.GetValue(0)
into an XML document, in base64 format. The code
seems to execute correctly, but generates an unhandled exception
in the debugger. Is it possible to add an element( a column) to
a DataSet and then read values into it ? This seems to be
what the code is doing.

Yes, it is.  Here's some code as an example (which should work).
// Get the dataset from whatever source you are using.
DataSet dataset = getDataSet();
// Create the column
DataColumn column = new DataColumn("ColumnName");
column.DataType = typeof(int);
column.DefaultValue = 0;
// Add the newly created column to the DataSet

In the above code "results" should be "dataset."  Sorry about the mixup.
