How to determine the ClientContext URL, Server relative while working on Sharepoint with Office 365.

我的目标是下载存储在Documents-> User Created Folder->下的文件。文件的数量。

My Goal is to download a file which is stored under Documents->User Created Folder-> LIst of files.

我正在使用以下代码

  ClientContext clientContext = new ClientContext("https://companyname.sharepoint.com");
            
            SecureString passWord = new SecureString();
            foreach (char c in "password".ToCharArray()) passWord.AppendChar(c);
            clientContext.Credentials = new SharePointOnlineCredentials("[e-mail]", passWord); 
            Web web = clientContext.Web;

            Microsoft.SharePoint.Client.File file = web.GetFileByGuestUrl(" ");
            clientContext.Load(file);

            ClientResult<Stream> stream = file.OpenBinaryStream();
            clientContext.ExecuteQuery();

您好 ，

ClientContext网址是您的网站网址，例如：

https：// yourtenant。 sharepoint.com/sites/TST

从文件夹下载文件的示例代码供您参考。

class Program
    {
        private static void CopyStream(Stream src, Stream dest)
        {
            byte[] buf = new byte[8192];

            for (; ; )
            {
                int numRead = src.Read(buf, 0, buf.Length);
                if (numRead == 0)
                    break;
                dest.Write(buf, 0, numRead);
            }
        }
        static void Main(string[] args)
        {
            string _SiteUrl = "https://domain.sharepoint.com/sites/tst";
            using (var clientContext = new ClientContext(_SiteUrl))
            {
                Console.ForegroundColor = ConsoleColor.Green;
                string password = "pw";
                SecureString sec_pass = new SecureString();
                Array.ForEach(password.ToArray(), sec_pass.AppendChar);
                sec_pass.MakeReadOnly();
                clientContext.Credentials = new SharePointOnlineCredentials("[e-mail]", sec_pass);

                Web web = clientContext.Web;
                Folder folder = web.GetFolderByServerRelativeUrl("/sites/TST/MyDoc4/Folder");
                var files = folder.Files;                
                clientContext.Load(files);
                clientContext.ExecuteQuery();
                Regex regex = new Regex(_SiteUrl, RegexOptions.IgnoreCase);
                string localPath =@"C:\Lee\FileDownload";

                foreach (var file in files)
                {
                    clientContext.Load(file);
                    Console.WriteLine(file.Name);
                    ClientResult<Stream> stream = file.OpenBinaryStream();
                    clientContext.ExecuteQuery();
                    var fileOut = Path.Combine(localPath, file.Name);

                    if (!System.IO.File.Exists(fileOut))
                    {
                        using (Stream fileStream = new FileStream(fileOut, FileMode.Create))
                        {
                            CopyStream(stream.Value, fileStream);
                        }
                    }
                }

                Console.WriteLine("done");
                Console.ReadKey();
            }

        }
    }
