Combining two results of datasets into one
提问by FredHomme
I have created a webservice which returns two datasets(return type) as results.
Is it possible to combine two datasets results into one so that I can display it on one datalist? I try using arraylistbut it returns nothing in datalist.
我创建了一个 web 服务，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，以便我可以将其显示在一个数据列表中？我尝试使用，arraylist但它在datalist.
GetDepartureFlightsDetails()and getDepartureFlights()both returns a dataset values.
GetDepartureFlightsDetails()并且getDepartureFlights()都返回一个数据集值。
Below is the method i use to retrieve the webservice results.
下面是我用来检索网络服务结果的方法。
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;
}

You can use the DataSet.Mergemethod:
您可以使用DataSet.Merge方法：
firstDataSet.Merge(secondDataSet);
Update:
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;
}

Can't you make a wrapper Class and use List<>of the wrapper class ,
rather than Datasets.
你不能创建一个包装类并使用List<>包装类，而不是Datasets.
