示例1: Find

		/// <summary>
		/// 	Returns rows from the DataSource that meet the parameter conditions.
		/// </summary>
		/// <param name="transactionManager"><see cref="TransactionManager"/> object</param>
		/// <param name="parameters">A collection of <see cref="SqlFilterParameter"/> objects.</param>
		/// <param name="orderBy">Specifies the sort criteria for the rows in the DataSource (Name ASC; BirthDay DESC, Name ASC);</param>
		/// <param name="start">Row number at which to start reading.</param>
		/// <param name="pageLength">Number of rows to return.</param>
		/// <param name="count">out. The number of rows that match this query.</param>
		/// <returns>Returns a typed collection of Nettiers.AdventureWorks.Entities.TransactionHistory objects.</returns>
