How can i download files and folder from share point

Hi Hardik Deshani

You can download all files from the document library using below code

static void Main(string[] args) {
var site = new ClientContext("http://sitename/");
var web = site.Web;
site.Load(web);
site.ExecuteQuery();
// Library name - Shared Documents
List list = web.Lists.GetByTitle("Shared Documents");
site.Load(list);
site.ExecuteQuery();
site.Load(list.RootFolder);
site.ExecuteQuery();
site.Load(list.RootFolder.Folders);
site.ExecuteQuery();
processFolderClientobj(list.RootFolder.ServerRelativeUrl);
foreach(Folder folder in list.RootFolder.Folders) {
processFolderClientobj(folder.ServerRelativeUrl);
}
}
public static void processFolderClientobj(string folderURL) {
string Destination = @
"c:\\temp";
var site = new ClientContext("http://sitename/");
var web = site.Web;
site.Load(web);
site.ExecuteQuery();
Folder folder = web.GetFolderByServerRelativeUrl(folderURL);
site.Load(folder);
site.ExecuteQuery();
site.Load(folder.Files);
site.ExecuteQuery();
foreach(Microsoft.SharePoint.Client.File file in folder.Files) {
string destinationfolder = Destination + "/" + folder.ServerRelativeUrl;
Stream fs = Microsoft.SharePoint.Client.File.OpenBinaryDirect(site, file.ServerRelativeUrl).Stream;
byte[] binary = ReadFully(fs);
if (!Directory.Exists(destinationfolder)) {
Directory.CreateDirectory(destinationfolder);
}
FileStream stream = new FileStream(destinationfolder + "/" + file.Name, FileMode.Create);
BinaryWriter writer = new BinaryWriter(stream);
writer.Write(binary);
writer.Close();
}
}
public static byte[] ReadFully(Stream input) {
byte[] buffer = new byte[16 * 1024];
using(MemoryStream ms = new MemoryStream()) {
int read;
while ((read = input.Read(buffer, 0, buffer.Length)) > 0) {
ms.Write(buffer, 0, read);
}
return ms.ToArray();
}
}
