我是SharePoint新手,希望使用C#ClientContext类和CAML Query删除SharePoint列表中的所有行.

我怎样才能有效地实现它？

Answer 1

我解决了 学习是我们需要以相反的顺序删除列表项.

ListItemCollection listItems = oList.GetItems(CamlQuery.CreateAllItemsQuery());
clientContext.Load(listItems,
                    eachItem => eachItem.Include(
                    item => item,
                    item => item["ID"]));
clientContext.ExecuteQuery();

var totalListItems = listItems.Count;
Console.WriteLine("Deletion in " + currentListName + "list:");
if (totalListItems > 0)
{
    for (var counter = totalListItems - 1; counter > -1; counter--)
    {
        listItems[counter].DeleteObject();
        clientContext.ExecuteQuery();
        Console.WriteLine("Row: " + counter + " Item Deleted");
    }
}
