剖析SharePoint:通过唯一的ID获取SPListItem [英] SharePoint: Get SPListItem by Unique ID
问题描述
我试图从一个独特的ID(GUID)得到一个SPListItem对象。通过观察几个网站(INC 的http:// sharepoint400 .blogspot.com / 2011/04 /使用-spsitedataquery找到的-list.html 和的 http://www.chakkaradeep.com/post/Retrieving-an-Item-from-the-RootWeb-and-Subwebs-利用其通UniqueId.aspx )我想出了下面的代码。
I am attempting to get an SPListItem object from a unique ID (GUID). From looking at several sites (inc. http://sharepoint400.blogspot.com/2011/04/using-spsitedataquery-to-find-list.html and http://www.chakkaradeep.com/post/Retrieving-an-Item-from-the-RootWeb-and-Subwebs-using-its-UniqueId.aspx) I came up with the code below.
const string QueryFormat =
@"<Where>
<Eq>
<FieldRef Name='UniqueId' />
<Value Type='Lookup'>{0}</Value>
</Eq>
</Where>";
SPSiteDataQuery query = new SPSiteDataQuery();
query.Webs = "<Webs Scope='SiteCollection' />";
query.Lists = "<Lists BaseType='0'/>";
query.Query = string.Format(QueryFormat, itemUniqueId);
query.RowLimit = 1;
//query.ViewFields = "<FieldRef Name='WebID' /><FieldRef Name='ListID' /><FieldRef Name='ID' />";
var results = SPContext.Current.Web.GetSiteData(query);
不过,无论怎样......我似乎总是得到零行返回。我不明白为什么,因为我知道我使用的GUID是正确的。
However, no matter what... I always seem to get zero rows returned. I don't understand why, because I know the Guids I am using are correct.
任何想法?
推荐答案
有一个无效类型唯一ID应该GUID。
更新查询:
There is an invalid type for Unique Id, it should be Guid. Update your query:
<Where>
<Eq>
<FieldRef Name='UniqueId'/>
<Value Type='Guid'>{0}</Value>
</Eq>
</Where>
