Mapping columns in a DataTable to a SQL table with SqlBulkCopy

I would like to know how I can map columns in a database table to the datatable in c# before adding the data to the database.

using (SqlBulkCopy s = new SqlBulkCopy(conn))
{
s.DestinationTableName = destination;
s.WriteToServer(Ads_api_ReportData);
}

You probably need some thing like

 public void BatchBulkCopy(DataTable dataTable, string DestinationTbl, int batchSize)
{
// Get the DataTable
DataTable dtInsertRows = dataTable;
using (SqlBulkCopy sbc = new SqlBulkCopy(connectionString, SqlBulkCopyOptions.KeepIdentity))
{
sbc.DestinationTableName = DestinationTbl;
// Number of records to be processed in one go
sbc.BatchSize = batchSize;
// Add your column mappings here
sbc.ColumnMappings.Add("field1","field3");
sbc.ColumnMappings.Add("foo","bar");
// Finally write to server
sbc.WriteToServer(dtInsertRows);
}
}
