SharePoint 2010 - 读取列表项错误“无法完成此操作，请重试。”

我有一个部署列表的SharePoint 2010服务器场解决方案，以及一个从该列表中读取的Web部件。它实际上不止于此，但我无法超越“阅读清单”部分。SharePoint 2010 - 读取列表项错误“无法完成此操作，请重试。”

我能够成功查询列表并获取SPListItemCollection，但是当我试图循环通过项目时，我得到这个完全模糊的错误“无法完成此操作，请重试。”全堆栈跟踪如下：

我看了列表定义好几次，它看起来声，从我所看到的网络部分代码。

下面的代码显示在那里我遇到了错误 - 再次，没有什么特别的：

SPQuery query = new SPQuery() { Query = this.filterQuery }; 

//Loop through the returned URL(s) and add them to the list 
foreach (SPItem item in list.getItems(query)) { //<-- Error happens here, when getting the enumerator for the SPListItemsCollection 
     returnValue.Add(this.getUrlFromItem(item)); 
}

最后，CAML：

<Where> 
    <FieldRef Name="Source" /> 
    <Value Type="Text">http://dev01:80/Pages/default.aspx</Value> 
</Where>

任何有关可能发生在这里的事情的想法都会被深深感激！

我发现了这个问题 - 糟糕的CAML语法。

坏CAML：

<Where> 
    <FieldRef Name="Source" /> 
    <Value Type="Text">http://dev01:80/Pages/default.aspx</Value> 
</Where>

正确的CAML：

<Where> 
    <Eq> 
    <FieldRef Name="Source" /> 
    <Value Type="Text">http://dev01:80/Pages/default.aspx</Value> 
    </Eq> 
</Where>

奇怪的是，我从来没有见过坏CAML语法导致这样的错误。

这实际上很常见，“无法完成此操作”=“CAML中的错误”，与我自己过去有一些“乐趣” – 2011-02-11 00:09:00
