从SharePoint 2010文档库检索文档

我正在将文档上传到文档库。与此同时，我通过组合2个值创建了一个名为“FieldID”的字段。但是，我无法在文档库中看到此字段，因此无法使用此字段查询文档。如何查看此字段或如何使用此“FieldID”检索文档。这是代码。从SharePoint 2010文档库检索文档

exposureLibrary.Fields.Add（fldID）; //在此步骤之后

//exposureLibrary.Update（）;

您需要取消注释，因为在尝试块中创建字段后，列表/库不会更新

有任何进一步的帮助。我想根据某些条件从文档库中检索文档并将其显示为链接。当链接被点击时，文档应该被打开。感谢您的帮助.. – user2028871 2014-11-11 07:52:50
