Answer 1

How about using the Text OBDC or OLE DB to access the text file contents?

You will have to:

• Decide from FixedLength, Delimited/etc, for the Text File Driver.
• Create a Schema Driver.
• Use the connection string to access the file.

• Use simple oledb commands to process the data in file. Or use a data adapter.

  string sql = "DELETE FROM yourFile WHERE ID=" + ID; ExecuteNonQuery(sql);
