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(); } }
