将多个SPList添加到SPListItemCollection

Question

我有一个SPList到一个SPListItemCollection，我想把两个SPList加到一个SPListItemCollection上

1

SPList list = SPContext.Current.Web.Lists[Constants.ListNames.Name];
SPListItemCollection allItems = list.GetItems(spQuery);

2

SPList list = SPContext.Current.Web.Lists[Constants.ListNames.Name];
SPList list2 = SPContext.Current.Web.Lists[Constants.ListNames.Name2];
    SPListItemCollection allItems = list.GetItems(spQuery);
allItems??? 

Answer 1

我总是喜欢使用List<>来处理这些问题。要做到这一点，请确保添加

using System.Linq;

然后

List<SPListItem> allItems = new List<SPListItem>();
allItems.AddRange(list.GetItems(spQuery).Cast<SPListItem>().ToList());
allItems.AddRange(list2.GetItems(spQuery).Cast<SPListItem>().ToList());

//Do something to the "allItems"

就这样
