将多个 SPList 添加到 SPListItemCollection

Question

我有 1 个 SPList 到 1 个 SPListItemCollection，我想将两个 SPList 添加到 1 个 SPListItemCollection

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

我一直喜欢用List<>来处理这些。为此，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"

就是这样
