将一个SharePoint项目分解成块的问题

问题描述：

我试图将我的SharePoint项目分解为几个较小的项目。我可以轻松地在不同的项目中移动实用程序文件。但是当我移动自定义字段时遇到问题。将一个SharePoint项目分解成块的问题

如果我将自定义字段从ProjectA移动到ProjectB，并将ProjectA设置为引用ProjectB的DLL，则构建和部署工作正常。但是，当程序从SPListItem引用自定义字段时，它会抛出System.ArgumentOutOfRangeException。

例如

SPListItem item = splist.GetItemById(id);<br> 
CustomFieldValue custom = item["Custom"] // Error occurs here

此外，如果我调用AddFieldAsXml来定义上述自定义字段，我会得到相同的错误。

谁能帮我解决这个问题吗？预先感谢您...

详细错误的发生AddFieldAsXml（引用时，会发生同样的错误）

我解决了这个问题... 我没有复制fldtypes_xxxx.xml信息。所以当代码尝试从xml读取一些信息时，抛出异常...
