Question

我正在尝试将我的sharepoint项目分解为几个较小的项目。我可以轻松移动不同项目中的实用程序文件。但是当我移动自定义字段时遇到了问题。

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，它将抛出System.ArgumentOutOfRangeException。

e.g。

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

另外，如果我调用AddFieldAsXml来定义上面的自定义字段，我会得到同样的错误。

谁能帮我解决这个问题？提前谢谢你......

如果string.substring（int startIndex，int length）的长度值为负，则显示此错误... 但我不知道为什么我会收到这个错误。

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中读取一些信息时，会抛出异常......
