SharePoint: Get List of Folders and Subfolders

Scenario:

A question on MSN requested for code to populate two drop downs from a document library. “DropDown A” should contain list of all the folders at the root. If we select any folder from “DropDown A”, “DropDown B” should be populated with list of all folders in the selected folder.

Resolution:

To get the list of all the folders at root, following code will help:

using(SPSite oSite = new SPSite(“Site_URL”))

{

SPWeb oWeb = oSite.OpenWeb();

SPList oList = oWeb.Lists[“DocumentLibraryName”];

SPFolderCollection oFolders = oList.RootFolder.SubFolders;

foreach (SPFolder oFolder in oFolders)

{

if (!oFolder.Name.Equals(“Forms”))

{

//use oFolder.Name property to populate DropDown A

}

}

}

Once selected, following code will populate “DropDown B” with list of subfolders:

SPFolder selFolder = oList.RootFolder.SubFolders[oList.Title + “/” + “Selected Folder Name”];

SPFolderCollection selSubFolders = selFolder.SubFolders;

foreach (SPFolder selSubFolder in selSubFolders)

{

//use subFolder.Name property to populate DropDown B

}
