I have an XML string which is output from a Visual Fox Pro based COM object that I am trying to read into a DataSet. When I do this it throws an exception “The string ” is not a valid AllXsd value.”
Based on googling and Stack Overflow searches this is normally a problem with a date format. I do have a field “Changed” of type datetime but I do not have any records in the XML with any data in this field. Assuming that field is causing the problem, and that I never need data from that field, how can I tell it to ignore data in that field or to treat it as a string or something.
Here’s the offending XML:
<?xml version = "1.0" encoding="Windows-1252" standalone="yes"?>

I got it to work by using XMLReadMode.InferSchema and I assume it is now treating that element as some type other than a date.
