How to use SQL bulk

Following C# syntax can be used for multiple insertion using sqlbulk:

 SqlBulkCopy bulkcpy = new SqlBulkCopy(con);
bulkcpy.ColumnMappings.Add("columnname1", "datasetcolumn_Name1");
bulkcpy.ColumnMappings.Add("columnname2", "datasetcolumn_Name2");
bulkcpy.ColumnMappings.Add("columnname3", "datasetcolumn_Name3");
bulkcpy.ColumnMappings.Add("columnname4", "datasetcolumn_Name4");
bulkcpy.ColumnMappings.Add("columnname5", "datasetcolumn_Name5");
bulkcpy.ColumnMappings.Add("columnname6", "datasetcolumn_Name6");

                      bulkcpy.DestinationTableName = "Database_TableName";
            bulkcpy.WriteToServer(DataTable);

Happy Coding !! :)
