Getting exception during fileupload to sharepoint in C#

Please see the code below. This is my initialization:
string siteUrl = "https://(*company domain*).sharepoint.com/sites/BankGuaranteeManagement/";
string documentLibrary = "BG Docs";
string fileName = VIEWSTATE_MAIN_FILE_NAME;
string customerFolder = "Bank Guarantees";
string userNameSP = "bgmfileuser#company.com";
string passwordSP = "hs#29n#$";
This is the fileupload code:
#region ConnectToSharePoint
string serverRelativeURL = "";
var securePassword = new SecureString();
foreach (char c in Password)
{ securePassword.AppendChar(c); }
System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;
var onlineCredentials = new SharePointOnlineCredentials(Login, securePassword);
#endregion
#region Insert the data
using (ClientContext clientContext = new ClientContext(siteUrl))
{
clientContext.Credentials = onlineCredentials;
Web web = clientContext.Web;
List libraryList = clientContext.Web.Lists.GetByTitle("Documents");
Folder folder = libraryList.RootFolder;
clientContext.Load(folder, f => f.ServerRelativeUrl);
clientContext.ExecuteQuery();
serverRelativeURL = folder.ServerRelativeUrl;
System.IO.FileStream fs = new System.IO.FileStream(filePath, System.IO.FileMode.Open, System.IO.FileAccess.Read);
Microsoft.SharePoint.Client.File.SaveBinaryDirect(clientContext, serverRelativeURL + "/" + System.IO.Path.GetFileName(filePath), fs, true);
}
#endregion
}
catch (Exception exp)
{
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine(exp.Message + Environment.NewLine + exp.StackTrace);
}
On clientContext.ExecuteQuery, I am getting the following error:
Exception
{"The sign-in name or password does not match one in the Microsoft account system."}
Some points worth mentioning:
The ID being used in credentials has MFA disabled.
The ID being used is part of the Active directory.
I can login into portal.office.com using the same ID and password. So, no issues there.
.Net version is 4.6
Latest Sharepoint dll is installed and added.
I went through all materials on internet but cannot figure this ont out. Any help will be useful. Thanks.

How to read the contents of a single file in SharePoint Online using C#

I have the following url which displays the metadata of the file when put in the browser but I want the actual file content.
https://mySite/_api/web/folders/getbyurl('Shared%20Documents')/folders/getbyurl('09.%20SharePoint%20Tutorials')/files/GetByUrl('SharePoint%20365%20Co-authoring%20excel%20files.docx')
I have tried doing the following but I just get a 400 error when trying to execute the query on line 4:
ClientContext clientContext = new ClientContext("mySite");
File f = clientContext.Web.Folders.GetByUrl("Shared Documents").Folders.GetByUrl("09. SharePoint Tutorials").Files.GetByUrl("SharePoint 365 Co-authoring excel files.docx");
clientContext.Load(f);
clientContext.ExecuteQuery();
FileInformation fileInformation = File.OpenBinaryDirect(clientContext, (string)f.ServerRelativeUrl);
using (System.IO.StreamReader sr = new System.IO.StreamReader(fileInformation.Stream))
{
String line = sr.ReadToEnd();
Console.WriteLine(line);
}

The code below for your reference:
string targetSiteURL = #"https://xx.sharepoint.com/sites/lz";
var login = "lz#xxx.onmicrosoft.com";
var password = "xxx";
var securePassword = new SecureString();
foreach (char c in password)
{
securePassword.AppendChar(c);
}
SharePointOnlineCredentials onlineCredentials = new SharePointOnlineCredentials(login, securePassword);
ClientContext ctx = new ClientContext(targetSiteURL);
ctx.Credentials = onlineCredentials;
var web = ctx.Web;
ctx.Load(web);
ctx.ExecuteQuery();
var filePath = web.ServerRelativeUrl + "/Shared%20Documents/09.%20SharePoint%20Tutorials/SharePoint%20365%20Co-authoring%20excel%20files.docx";
FileInformation fileInformation = Microsoft.SharePoint.Client.File.OpenBinaryDirect(ctx, filePath);
using (System.IO.StreamReader sr = new System.IO.StreamReader(fileInformation.Stream))
{
String line = sr.ReadToEnd();
Console.WriteLine(line);
}
Console.ReadKey();

403 error on Client.executeQuery()

I am trying to retrieve some information from a Office 365 site. I am getting a inconsistent 403 error on executeQuery call. This happens irregularly and is solved by IISReset. Please help.
ClientContext clientContext = new ClientContext(Constants.SP_URL);
{
SecureString passWord = new SecureString();
foreach (char c in Constants.SP_SERVICE_PASS.ToCharArray()) passWord.AppendChar(c);
var cred = new SharePointOnlineCredentials(Constants.SP_SERVICE_ACC, passWord); ;
clientContext.Credentials = new SharePointOnlineCredentials(Constants.SP_SERVICE_ACC, passWord);
Web web = clientContext.Web;
string docLibraryName = Constants.SP_PUBLISHED_LIB;
var list = clientContext.Web.Lists.GetByTitle(docLibraryName);
clientContext.Load(list);
**clientContext.ExecuteQuery();**

Here is what you need to get a client context and load your data.This authenticate you against SP Online in office 365. I do not know how would you say i reset my IIS. This is not applicable unless you connect to a local SP instance.
private void AutheticateO365(string url, string password, string userName)
{
Context = new ClientContext(url);
var passWord = new SecureString();
foreach (char c in password.ToCharArray()) passWord.AppendChar(c);
Context.Credentials = new SharePointOnlineCredentials(userName, passWord);
var web = Context.Web;
Context.Load(web);
Context.ExecuteQuery();
}

Authenticating Sharepoint site from background service and uploading file

I'm trying to authenticate up against Sharepoint so that it's possible for me to upload files onto a specific Sharepoint site.
I'm trying to use an X.509 certificate to retrieve the access token, but I keep getting (401): Unauthorized.
Here's the way I try to retrieve the access token with the certificate:
string authority = SettingsHelper.Authority;
string clientID = SettingsHelper.ClientId;
string serverName = SettingsHelper.SharepointServerName;
//Retreive the certificate path
string certFile = Server.MapPath(SettingsHelper.CertificatePath);
string certPassword = SettingsHelper.CertificatePassword;
AuthenticationResult authenticationResult = null;
AuthenticationContext authenticationContext = new AuthenticationContext(authority);
//Create the certificate file, using the path (certFile), password (certPassword) and the MachineKeySet
X509Certificate2 cert = new X509Certificate2(certFile, certPassword, X509KeyStorageFlags.MachineKeySet);
//Create the ClientAssertionCertificate using the clientID and the actual certificate
ClientAssertionCertificate cac = new ClientAssertionCertificate(clientID, cert);
//Retreive the access token using the serverName and client assertion
authenticationResult = authenticationContext.AcquireToken(serverName, cac);
And here's how I try to upload a specific file onto a specific Sharepoint list:
WebRequest request = null;
HttpWebResponse response = null;
byte[] bytesToUpload = bytes;
var returnValue = "";
string requestUriString = string.Format("{0}/_api/web/GetFolderByServerRelativeUrl(#sru)/Files/Add(url=#fn,overwrite=true)?#sru='{1}'&#fn='{2}'", url, HttpUtility.UrlEncode(serverRelativeUrl), HttpUtility.UrlEncode(fileName));
request = (HttpWebRequest)HttpWebRequest.Create(requestUriString);
request.Method = "POST";
(request as HttpWebRequest).Accept = "*/*";
request.ContentType = "application/json;odata=verbose";
request.Headers.Add("Authorization", String.Format("Bearer {0}", authenticationResult.AccessToken));
request.ContentLength = bytesToUpload.Length;
// Write the local file to the remote system
using (Stream requestStream = request.GetRequestStream())
{
BinaryWriter writer = new BinaryWriter(requestStream);
writer.Write(bytesToUpload, 0, bytesToUpload.Length);
writer.Close();
}
// Get a web response back
response = (HttpWebResponse)request.GetResponse();
using (StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.Default))
{
returnValue = sr.ReadToEnd();
sr.Close();
}
if (request.RequestUri.ToString().Contains("GetFolderByServerRelativeUrl") == true)
{
returnValue = "";
}
Some of the variables comes from the parameters:
UploadEmail(System.IO.File.ReadAllBytes(emlFilePath), "https://(blablabla).sharepoint.com", "sites/(bla)/(bla)/Emails", email.Subject + ".msg");
I'm not sure what's wrong, and I'm definitely not sure how to fix this.
NOTE: Please don't tell me to use NetworkCredentials, I'd rather use the certificate or something else, but not NetworkCredentials
EDIT
Managed to debug the code and find this in the response header of the WebRequest:

The better approach would be using the SharePoint Client Side Object Model (as hbulens suggested in comments).
Here's the code that uploads the file to the library in O365 (just replace the string literals with your own details):
string username = "YOUR_USERNAME";
string password = "YOUR_PASSWORD";
string siteUrl = "https://XXX.sharepoint.com";
ClientContext context = new ClientContext(siteUrl);
SecureString pass = new SecureString();
foreach (char c in password.ToCharArray()) pass.AppendChar(c);
context.Credentials = new SharePointOnlineCredentials(username, pass);
Site site = context.Site;
context.Load(site);
context.ExecuteQuery();
Web web = site.OpenWeb("YOUR_SUBSITE");
context.Load(web);
context.ExecuteQuery();
List docLib = web.Lists.GetByTitle("YOUR_LIBRARY");
context.Load(docLib);
FileCreationInformation newFile = new FileCreationInformation();
string filePath = #"YOUR_LOCAL_FILE";
newFile.Content = System.IO.File.ReadAllBytes(filePath);
newFile.Url = System.IO.Path.GetFileName(filePath);
Microsoft.SharePoint.Client.File uploadFile = docLib.RootFolder.Files.Add(newFile);
context.Load(uploadFile);
context.ExecuteQuery();
You can run it in console application. Two dll's that you need to reference are:
Microsoft.SharePoint.Client.dll
Microsoft.SharePoint.Client.Runtime.dll

Office 365 Sharepoint Upload Files to Documents Library

I am trying to use the following code to add files to my document library on Sharepoint Office365 using web services.
public void SaveFileToSharePoint(string fileName)
{
try
{
var copyService = new Copy { Url = "https://mydomain.com/_vti_bin/copy.asmx", Credentials = new NetworkCredential("username", "password", "domain") };
var destURL = "https://mydomain.com/Shared%20Documents/" + Path.GetFileName(fileName);
string[] destinationUrl = { destURL };
CopyResult[] cResultArray;
var fFiledInfo = new FieldInformation { DisplayName = "Description", Type = FieldType.Text, Value = Path.GetFileName(fileName) };
FieldInformation[] fFiledInfoArray = {fFiledInfo};
var copyresult = copyService.CopyIntoItems(destURL, destinationUrl, fFiledInfoArray, File.ReadAllBytes(fileName), out cResultArray);
var b = copyresult;
}
catch (Exception ex)
{
}
}
I receive the error "Object Moved". The URL loads the WSDL in the browser though. If there is a better way to upload and get files from SharePoint on Office365 online I would entertain that as well. Thanks.

as the ASMX webservices are deprecated you should check out the "new" rest services of sharepoint. ON MSDN you find information about it
Or you can use the Client object model which would be my favorite way. The following example shows basic usage, to connect to SharePoint online check out the following link
using(ClientContext context = new ClientContext("http://yourURL"))
{
Web web = context.Web;
FileCreationInformation newFile = new FileCreationInformation();
newFile.Content = System.IO.File.ReadAllBytes(#"C:\myfile.txt");
newFile.Url = "file uploaded via client OM.txt";
List docs = web.Lists.GetByTitle("Documents");
Microsoft.SharePoint.Client.File uploadFile = docs.RootFolder.Files.Add(newFile);
context.ExecuteQuery();
}

Using roqz suggestions above, here is the ultimate solution I came up with to place files in the SharePoint 2013 Office 365 document library and to retrieve them by name:
public void SaveFileToSharePoint(string fileName)
{
using (var context = new ClientContext("https://mydomain.com/"))
{
var passWord = new SecureString();
foreach (var c in "MyPassword") passWord.AppendChar(c);
context.Credentials = new SharePointOnlineCredentials("me#mydomain.com", passWord);
var web = context.Web;
var newFile = new FileCreationInformation {Content = File.ReadAllBytes(fileName), Url = Path.GetFileName(fileName)};
var docs = web.Lists.GetByTitle("Documents");
docs.RootFolder.Folders.GetByUrl("Test").Files.Add(newFile);
context.ExecuteQuery();
}
}
public void GetFileFromSharePoint(string fileName, string savePath)
{
using (var context = new ClientContext("https://mydomain.com/"))
{
var passWord = new SecureString();
foreach (var c in "MyPassword") passWord.AppendChar(c);
context.Credentials = new SharePointOnlineCredentials("me#mydomain.com", passWord);
var web = context.Web;
var myFile = web.Lists.GetByTitle("Documents").RootFolder.Folders.GetByUrl("Test").Files.GetByUrl(fileName);
context.Load(myFile);
context.ExecuteQuery();
using (var ffl = Microsoft.SharePoint.Client.File.OpenBinaryDirect(context, myFile.ServerRelativeUrl))
{
using (var destFile = File.OpenWrite(savePath + fileName))
{
var buffer = new byte[8*1024];
int len;
while ((len = ffl.Stream.Read(buffer, 0, buffer.Length)) > 0)
{
destFile.Write(buffer, 0, len);
}
}
}
}
}
