sharepoint - 错误代码 : 3604 when deleting file from SharePoint Document Library

Question

我正在 SharePoint 2007 中开发 WebPart，有时当我尝试使用如下代码从文档库中删除文件时:

SPWeb web = SPControl.GetContextWeb(WebPart.WebPartContext);

SPList list = web.GetList(web.Site.Url + "/ListName");

SPFile file = list.GetItemByUniqueId(new Guid(fileId)).File;

file.Delete();

我得到以下异常:

Cannot remove file "filename.bmp". Error Code: 3604.<p></p>

Stack Trace: 
at Microsoft.SharePoint.Library.SPRequest.AddOrDeleteUrl(String bstrUrl, String bstrDirName, Boolean bAdd, UInt32 dwDeleteOp, Int32 iUserId, Guid& pgDeleteTransactionId)
at Microsoft.SharePoint.SPFile.DeleteCore(DeleteOp deleteOp)
at Microsoft.SharePoint.SPFile.Delete()

SPFile 对象不为空。

知道为什么会这样吗？

我唯一能想到的可能是该文件当前已 checkout 或锁定以供其他用户编辑。试试这个...

SPWeb web = SPControl.GetContextWeb(WebPart.WebPartContext);
SPList list = web.GetList(web.Site.Url + "/ListName");
SPFile file = list.GetItemByUniqueId(new Guid(fileId)).File;

if (file.CheckOutStatus != SPFile.SPCheckOutStatus.None)
{
  file.UndoCheckOut();
  file.CheckOut();
}

file.Delete();
