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

 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();


}
