Unable to upload the documents in SharePoint Online using a console application. Any solution to this problem?

public static void SaveFileToSharePoint(string fileName)

       string Url = "https://xxxxx.sharepoint.com/sites";
       string libraryName = "Shared Documents";

        using (ClientContext clientContext = new ClientContext(Url))
                            SecureString passWord = new SecureString();
                            foreach (char c in "*****".ToCharArray()) passWord.AppendChar(c);
                            clientContext.Credentials = new SharePointOnlineCredentials("xxxx@xxxgmail.onmicrosoft.com",
                            List list = clientContext.Web.Lists.GetByTitle(libraryName);
                            using (FileStream fileStream = new FileStream(fileName, FileMode.Open))
                                Microsoft.SharePoint.Client.File.SaveBinaryDirect(clientContext, list.RootFolder.ServerRelativeUrl.ToString() + "/" + fileName.Split('\\')[1], fileStream, true);


You should refer this link once. This post contains the code for authenticating with your SharePoint Online and upload a file into the given library.

 class Program
        static void Main(string[] args)
            using (ClientContext clientContext = new ClientContext("https://xxxx.sharepoint.com/sites/SiteName"))
                SecureString passWord = new SecureString();
                foreach (char c in "YourPassword".ToCharArray()) passWord.AppendChar(c);
                clientContext.Credentials = new SharePointOnlineCredentials("username@domain.onmicrosoft.com", passWord);
                Web web = clientContext.Web;
                FileCreationInformation newFile = new FileCreationInformation();
                newFile.Content = System.IO.File.ReadAllBytes(@"C:\Applications\PropertyMaster.xlsx"); // this is my sample file path
                newFile.Url = "testFile.xlsx"; // file name which should be created in library

                List docs = web.Lists.GetByTitle("Library Name");
                Microsoft.SharePoint.Client.File uploadFile = docs.RootFolder.Files.Add(newFile);

The above code worked for me.

  • I tried that code also but it's of no use. – Amitabha May 2 '16 at 10:51
  • I have implemented the above code and it worked for me. Let me know the error or issue which you are facing. – Aakash Maurya May 2 '16 at 11:15
  • @Amitabha What permissions does your user (xxxx@xxxgmail.onmicrosoft.com) have on the site? You may want to also check out this question: sharepoint.stackexchange.com/questions/70562/…. There are a couple ways to upload files via CSOM. See this MSDN post: msdn.microsoft.com/en-us/library/office/dn904536.aspx. – nsturdivant May 2 '16 at 11:30
