How to Read Hyphenated values from CSV File?

Hi,

I'm using the OleDB namespace to open a CSV File. I can read the file
sucessfully except for hyphenated values. My CSV File contains phone numbers
and sometimes these come separated with hyphens (ie: 555-123-4567). These
fields come as empty using the OleDB namespace and as dbNull when using the
ODBC namespace. Is there a way to prevent this from happening?

Thanks in advance,
