集合尚未初始化 [英] The collection has not been initialized

问题描述

我正在尝试使用 CSOM 从Sharepoint库中检索所有项目，并创建一个列表.我确信这与代码的顺序有关.问题是如何?

I am trying to retrieve all items from a Sharepoint library with CSOM and create a list of it. I am sure it has something to do with the order of the code. The question is how?

ListItemCollection collListItem = oList.GetItems(camlQuery);
var newList = new List<Item>();
var items = oList.GetItems(camlQuery);
context.Load(collListItem);

context.ExecuteQuery();

foreach (var col in items)
{

    newList.Add(new Item()
    {
        ID = Convert.ToInt32(col["ID"]),

    });
}

我收到以下错误:

该集合尚未初始化.尚未请求或尚未执行请求.可能需要明确要求

The collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested

推荐答案

您应该已加载 items 对象而不是 collListItems 对象，因此您的代码应如下所示:

You should have loaded the items object not the collListItems thus your code should look following:

ListItemCollection collListItem = oList.GetItems(camlQuery);
var newList = new List<Item>();
var items = oList.GetItems(camlQuery);
context.Load(items);
context.ExecuteQuery();
