Example

Wrapping a group of inserts in a transaction will speed them up according to this StackOverflow Question/Answer.

You can use this technique, or you can use Bulk Copy to speed up a series of related operations to perform.

// Widget has WidgetId, Name, and Quantity properties
public void InsertWidgets(IEnumerable<Widget> widgets)
{
    using(var conn = new SqlConnection("{connection string}")) {
        conn.Open();

        using(var tran = conn.BeginTransaction()) {
            try
            {
                var sql = "insert Widget (WidgetId,Name,Quantity) Values(@WidgetId, @Name, @Quantity)";
                conn.Execute(sql, widgets, tran);
                tran.Commit();
            }
            catch(Exception ex)
            {
                tran.Rollback();
                // handle the error however you need to.
                throw;
            }
        }
    }   
}
