c語言表白程序

項(xiàng)目程序里有如下方法定義：

/// <summary>
/// 將數(shù)據(jù)批量insert到db表里
/// </summary>
/// <param name="table"></param>
/// <param name="tableColumName"></param>
/// <param name="destinationTableName"></param>
/// <returns></returns>
public bool BulkCopy(DataTable table, string[] tableColumName, string destinationTableName = "T_AlipayRefundRecord")
{
    return OrderDataSave.MySqlBulkCopy(table, destinationTableName, tableColumName);
}

通過檢測調(diào)用代碼，發(fā)現(xiàn)都是這樣的：

var dt = new DataTable();
......
......
string[] sTableColumName = CommonFun.GetColumNameOfDataTable(dt);
// 將退款數(shù)據(jù)批量insert到dbo.T_AlipayRefundRecord表里
bResult = alipayRefundBll.BulkCopy(dt, sTableColumName);

既然如此，那么，我認(rèn)為，有必要把獲取DataTable列數(shù)組的行遷移到BulkCopy方法里，實(shí)現(xiàn)封裝。
即方法BulkCopy的方法體為：

public bool BulkCopy(DataTable table, string destinationTableName = "T_AlipayRefundRecord")
{
    string[] tableColumName = CommonFun.GetColumNameOfDataTable(dt);
    return OrderDataSave.MySqlBulkCopy(table, destinationTableName, tableColumName);
}

這樣調(diào)用的代碼就更簡潔了：

var dt = new DataTable();
......
......
// 將退款數(shù)據(jù)批量insert到dbo.T_AlipayRefundRecord表里
bResult = alipayRefundBll.BulkCopy(dt);
