備註

使用SPWeb類別的Folders屬性或SPFolder類別的SubFolders屬性來傳回SPFolderCollection物件，表示集合的網站或資料夾的資料夾。若要從集合傳回單一資料夾中使用索引子。例如，如果集合指派給一個名為collFolders變數中，使用在 C# 的collFolders[index]或 Visual Basic，其中index是集合中資料夾的索引編號，或者是顯示名稱的資料夾中的collFolders(index) 。

Examples

下列程式碼範例會顯示資料夾的相關資訊網站和所有子網站，包括網站名稱、資料夾名稱、檔案數目，在資料夾和檔案的總大小。

這個範例要求using指示詞 (在 Visual Basic 的Imports ) 的Microsoft.SharePoint和Microsoft.SharePoint.Utilities命名空間。

這個範例也會要求包含 label 控制項的預先定義的.aspx 網頁。

Dim siteCollection As SPSite = SPControl.GetContextSite(Context)
Dim sites As SPWebCollection = siteCollection.AllWebs
Dim site As SPWeb

For Each site In  sites

    Dim folders As SPFolderCollection = site.Folders
    Dim folder As SPFolder

    For Each folder In  folders

        Dim files As SPFileCollection = folder.Files
        Dim totalFileSize As Long = 0
        Dim i As Integer

        For i = 0 To files.Count - 1
            totalFileSize += files(i).Length
        Next i

        Label1.Text += " Web: " & SPEncode.HtmlEncode(site.Name) 
            & " Folder: " _
            & SPEncode.HtmlEncode(folder.Name) & " Number: " 
                & folder.Files.Count _
            & " Size: " & totalFileSize & "<BR>"

    Next folder

Next site

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();
}

注意事項
某些物件實作IDisposable介面，並且您必須避免之後不再需要保留這些物件在記憶體中。良好的程式碼撰寫方式的相關資訊，請參閱Disposing Objects。
