以編程方式將Sharepoint列表的現有項目添加到文件夾

Question

我在SharePoint 2010列表中有大約20K項目，我希望以編程方式安排每個5k項目在文件夾中，並且確保新添加的項目也在文件夾中達到5k的限制。

我還沒有在編程方式上在SharePoint中創建文件夾。有人可以幫我一段代碼。

Answer 1

對於在SPList中創建文件夾，使用下面的示例代碼它會幫助你。

SPSite oSite = new SPSite("http://localhost/"); 
SPWeb oWeb = oSite.OpenWeb(); 
//Provide SPList name which you use... 
SPList oList = oWeb.Lists["testlist"]; 
oWeb.AllowUnsafeUpdates = true; 
//Add a Folder as List Item in SPList as below 
SPListItem folderItem = oList.Items.Add(oList.RootFolder.ServerRelativeUrl, SPFileSystemObjectType.Folder);    
//Add Folder Title here 
folderItem["Title"] = "1-5000-Items-Folder"; 
folderItem.Update(); 

oWeb.AllowUnsafeUpdates = false;

請使用CAML查詢來循環SP中的文件夾。也絕對不要使用list.Items.Add（）而是使用listitems.add（）。 http://stackoverflow.com/faq#signatures -

SPQuery query = new SPQuery(); 
query.Query = "<Where><And><Eq><FieldRef Name='LinkTitle'/><Value Type='Text'>" +folderName + "</Value></Eq><Eq><FieldRef Name='FSObjType'/><Value Type='Lookup'>1</Value></Eq></And></Where>";query.ViewAttributes = "Scope=\"RecursiveAll\""; 
SPListItemCollection items = list.GetItems(query); 
if (items.Count == 0){Create a folder} 
else{ 
SPListItem listItem = list.AddItem(folderItem.Folder.ServerRelativeUrl,SPFileSystemObjectType.File, null);}
