I had some requirements from client, for fulfilling that I had to write a code for getting list of all documents from folders/sub-folders from a SharePoint library.
Below is the code which I used:
===========================MAIN METHOD================================
private void OCR_Document()
{
try
{
SPWebApplication webApp = SPWebApplication.Lookup(new Uri("webapplication URL"));
//iterates in each site and subsites
foreach (SPSite site in webApp.Sites)
{
foreach (SPWeb web in site.AllWebs)
{
//iterates in each lists/libraries
foreach (SPList list in web.Lists)
{
//selects only document libraries
if (Convert.ToString(list.BaseType) == "DocumentLibrary")
{
//check if document library contains folder
if (list.Folders.Count > 0)
{
SPQuery query = new SPQuery();
query.Folder = list.RootFolder;
SPListItemCollection itemCollection = web.Lists[list.RootFolder.ParentListId].GetItems(query);
foreach (SPListItem subitem in itemCollection)
{
//iterate in each folder-subfolder, all folders will come into this loop
if (subitem.ContentType.Name == "Folder")
{
iterateFolder(subitem.Folder);
}
else
{
//here you will get only files in subitem varialbe
//write your code here for files
}
}
}
else
{
foreach (SPFile file in list.RootFolder.Files)
{
//here you will get only files
//write your code here for files
}
}
}
}
}
}
}
catch
{
throw;
}
}
===========================ITERATE FOLDER METHOD====================
private void iterateFolder(SPFolder folder)
{
if (folder.SubFolders != null)
{
//check for subfolders
foreach (SPFolder item in folder.SubFolders)
{
//scroll through each subfolder and each child folder
iterateFolder(item.SubFolders.Folder);
}
}
foreach (SPFile file in folder.Files)
{
//here you will get only files
//write your code here for files
}
}
