Invalid character value for cast specification

问题

I am inserting data into SQL 2005 using SQLXMLBulkLoad.SQLXMLBulkload.3.0

My data table has following column: objDataTable.Columns.Add("TaskDateTime", System.Type.GetType("System.DateTime"))

My bulk insert schema has following definition: <xsd:element name="DepartureTime" type="xsd:date" /> (Using xmlns:xsd="http://www.w3.org/2001/XMLSchema")

And I am getting 'Invalid character value for cast specification' exception.

Any advice?

Solved!.

Changed column type from: objDataTable.Columns.Add("TaskDateTime", System.Type.GetType("System.DateTime")) to objDataTable.Columns.Add("TaskDateTime", System.Type.GetType("System.String"))

and I am storing my value as .ToString("yyyy-MM-dd HH:mm") + ":00+00:00" in the data table. when creating XML file on disk, it simply writes it as string and the schema file for bulk insert reads it as datetime.

The problem is blanks in the source columns........ this is what is causing the invalid character value for cast specification.
