SPAttachmentCollection class
表示清單項目的附件集合。
Inheritance hierarchy
System.Object
Microsoft.SharePoint.SPAttachmentCollection
Namespace: Microsoft.SharePoint
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
Syntax
'宣告
Public Class SPAttachmentCollection _
Implements ICollection, IEnumerable
'用途
Dim instance As SPAttachmentCollection
public class SPAttachmentCollection : ICollection,
IEnumerable
備註
使用SPListItem類別的Attachments屬性,傳回的清單項目的附件集合。若要建立附件,請使用Add方法
若要從集合傳回單一附件的檔案名稱中使用索引子。例如,假設集合指派給變數,名為collAttachments ,使用在 C# 的collAttachments[index]或Visual Basic,在collAttachments(index)index所在集合中的附件索引編號。
Examples
下列程式碼範例示範如何將從共用文件的文件庫的所有檔案都附加在清單中會出現在 [網站] 下方的每一個子網站的第一個清單項目。
SPAttachmentCollection類別的Add方法需要做為參數傳遞檔案,以二進位格式。因此,本範例使用OpenBinary方法的SPFile類別若要開啟的資料夾中的每個檔案以二進位格式。
Dim oSiteCollection As SPSite = SPContext.Current.Site
Dim collWebsites As SPWebCollection = oSiteCollection.AllWebs
Dim oWebsite As SPWeb = collWebsites("Site_Name")
Dim oFolder As SPFolder = oWebsite.Folders("Shared Documents")
For Each oWebsiteNext As SPWeb In collWebsites
Dim oList As SPList = oWebsiteNext.Lists("List_Name")
Dim collItem As SPListItemCollection = oList.Items
Dim oListItem As SPListItem = collItem(0)
Dim collAttachments As SPAttachmentCollection = oListItem.Attachments
Dim collFiles As SPFileCollection = oFolder.Files
For Each oFile As SPFile In collFiles
Dim strFileName As String = oFile.Name
Dim binFile As Byte() = oFile.OpenBinary()
collFiles.Add(strFileName, binFile)
Next oFile
oListItem.Update()
oWebsiteNext.Dispose()
Next oWebsiteNext
oWebsite.Dispose()
SPSite oSiteCollection = SPContext.Current.Site;
SPWebCollection collWebsites = oSiteCollection.AllWebs;
SPWeb oWebsite = collWebsites["Site_Name"];
SPFolder oFolder = oWebsite.Folders["Shared Documents"];
foreach (SPWeb oWebsiteNext in collWebsites)
{
SPList oList = oWebsiteNext.Lists["List_Name"];
SPListItemCollection collItem = oList.Items;
SPListItem oListItem = collItem[0];
SPAttachmentCollection collAttachments = oListItem.Attachments;
SPFileCollection collFiles = oFolder.Files;
foreach (SPFile oFile in collFiles)
{
string strFileName = oFile.Name;
byte[] binFile = oFile.OpenBinary();
collFiles.Add(strFileName, binFile);
}
oListItem.Update();
oWebsiteNext.Dispose();
}
oWebsite.Dispose();
