将两个数据集结果合并为一个

Question

我创建了一个webservice,它返回两个数据集(返回类型)作为结果.是否可以将两个数据集结果合并为一个,以便我可以在一个数据列表中显示它？我尝试使用arraylist但它没有返回任何内容datalist.

GetDepartureFlightsDetails()并且getDepartureFlights()都返回数据集值.

下面是我用来检索Web服务结果的方法.

public ArrayList GetDepartureFlightsDetails(String departurecountry, String arrivalcountry, DateTime departuredate)   
{
    DLSA datalayerTS = new DLSA();
    DLJS datalayerJW = new DLJS();

    ArrayList array = new ArrayList();

    array.Add(datalayerSA.GetDepartureFlightsDetails(departurecountry, arrivalcountry, departuredate));
    array.Add(datalayerJW.getDepartureFlights(departurecountry, arrivalcountry, departuredate));
    return array;
}

Answer 1

您可以使用DataSet.Merge方法:

firstDataSet.Merge(secondDataSet);

更新:

public DataSet GetDepartureFlightsDetails(String departurecountry, String arrivalcountry, DateTime departuredate)
{
    DLSA datalayerTS = new DLSA();
    DLJS datalayerJW = new DLJS();

    var firstDataSet = datalayerSA.GetDepartureFlightsDetails(departurecountry, arrivalcountry, departuredate));
    var secondDataSet = datalayerJW.getDepartureFlights(departurecountry, arrivalcountry, departuredate));
    firstDataSet.Merge(secondDataSet);

    return firstDataSet;
}
