Linq to XML issues

Asked by alan_ITG in Language Integrated Query - LINQ

Tags: Linq to XML VB.Net, Internet Explorer 6.0

Hi,

I am trying to import an MS Excel XML document (2003 version of XL).

The code being used is as shown.

The issues I have are as follows:-

1) The For Each R in Sheet....<Row> section works fine and iterates through the rows in the document.
However, when the code reaches the Linq query (even when the loop is commented out) the Linq query returns a NULLReference Error.

Any ideas why?

2) Often when setting up Linq queries the variable in the for each loop (x in this case) used to iterate through the Linq query results generates an error in VB. The error states that the variable has not been defined.

I believe that these variables do not have to be defined as they are anonymous types. Can someone advise why this error happens?

regards,

Alan
