Question

我正在尝试从sharepoint 2013在线列表中检索一些项目。我确信列表中有3个项目。不知何故，代码不会返回任何项目。有谁知道为什么不呢？在调试中，listItems为空。

User spUser = null;
SharePointContextToken contextToken;
string accessToken;
Uri sharepointUrl;

string contextTokenString = TokenHelper.GetContextTokenFromRequest(Request);

if (contextTokenString != null)
{
    contextToken = TokenHelper.ReadAndValidateContextToken(contextTokenString, Request.Url.Authority);
    sharepointUrl = new Uri(Request.QueryString["SPHostUrl"]);
    accessToken = TokenHelper.GetAccessToken(contextToken, sharepointUrl.Authority).AccessToken;
    var clientContext = TokenHelper.GetClientContextWithAccessToken(sharepointUrl.ToString(), accessToken);
    Web web = clientContext.Web;
    List list = clientContext.Web.Lists.GetByTitle("CustomListFacturen");

    clientContext.Load(list);

    CamlQuery query = new CamlQuery();
    query.ViewXml = "<View><RowLimit>100</RowLimit></View>";

    ListItemCollection listItems = list.GetItems(query);
    clientContext.Load(listItems);
    clientContext.ExecuteQuery();

    if (listItems.Any())
    {
        ViewBag.Message = "Items are found!!!";
    }
}

Answer 1

我没有尝试运行您的代码，但它看起来几乎与此代码basic CSOM list operations完全相同。

您首先不需要.Load(list)，您可以尝试使用CamlQuery.CreateAllItemsQuery(100)代替CAML。

Answer 2

您的应用没有足够的权限。
