{}DataTable dt = CreateTempTable(dv);WriteDataTable(dt, outputFile, mode);You create a temporary DataTable object and then serialize it to XML using thepreviously defined methods. The structure of the internal CreateTempTable routine isfairly simple, as shown here:private static DataTable CreateTempTable(DataView dv){// Create a temporary DataTable with the same structure// as the originalDataTable dt = dv.Table.Clone();// Fill the DataTable with all the rows in the viewforeach(DataRowView rowview in dv)dt.ImportRow(rowview.Row);}return dt;The ImportRow method creates a new row object in the context of the table. Like manyother ADO.NET objects, the DataRow object can't be referenced by two containerobjects at the same time. Using ImportRow is logically equivalent to cloning the row andthen adding the clone as a reference to the table.
