学习：SharePoint 使用 SPQuery.Folder 查询文件夹中的数据

 在SharePoint中通过SPQuery.Folder属性, 可以很方便的查询列表下文件夹中的数据, 下面介绍如何使用:

•      SPQuery.Folder: Gets or sets the folder within a document library from which to return items in the query.

•      Demo:

using (SPWeb oWebsiteRoot = SPContext.Current.Site.RootWeb)

{



    oWebsiteRoot.Lists.IncludeRootFolder = true;

    SPList oList = oWebsiteRoot.Lists["Document_Library_Name"];

    SPFolder oFolder = oList.RootFolder.SubFolders["Folder_Name"];



    SPQuery oQuery = new SPQuery();

    oQuery.Folder = oFolder;

    SPListItemCollection collListItems = oList.GetItems(oQuery);



    foreach (SPListItem oListItem in collListItems)

    {

        Response.Write(SPEncode.HtmlEncode(oListItem.File.Name) + 

          "<BR>");

    }

}

• SPFolder:

SPSite oSiteCollection = SPContext.Current.Site;

SPWebCollection collWebsites = oSiteCollection.AllWebs;

foreach (SPWeb oWebsite in collWebsites)

{

    SPFolderCollection collFolders = oWebsite.Folders;



    foreach (SPFolder oFolder in collFolders)

    {

        SPFileCollection collFiles = oFolder.Files;



        long lngTotalFileSize = 0;



        for (int intIndex = 0; intIndex < collFiles.Count; intIndex++)

        {

            lngTotalFileSize += collFiles[intIndex].Length;

        }



            Label1.Text += " Web: " + 

                SPEncode.HtmlEncode(oWebsite.Name)

                + " Folder: " +

                SPEncode.HtmlEncode(oFolder.Name) + " Number: "

                + oFolder.Files.Count +

                " Size: " + lngTotalFileSize + "<BR>";

    }

    oWebsite.Dispose();



}
