C# Application to upload file to SharePoint with MFA

I am creating a Windows Form Application to insert data into MSSQL but also upload a file of user's choosing to SharePoint.
I tried to use the below code, however I have some serious problem due to Multi-Factor Authentication (MFA) not being lifted for my service account. IT is very firm on this matter.
string SiteUrl = "https://company.sharepoint.com/sites/mySite";
string DocumentLibrary = "Documents";
string FileName = #chkAttach1.Text.ToString();
string CustomerFolder = "Application Test";
string Username = "testuser";
string Password = "123";
foreach (char c in Password)
{ securePassword.AppendChar(c); }
var olCred = new SharePointOnlineCredentials(UserName, securePassword);
using (ClientContext cContext = new ClientContext(SiteUrl))
{
cContext.Credentials = olCred;
Web web = cContext.Web;
FileCreationInformation newFile = new FileCreationInformation();
byte[] FileContent = System.IO.File.ReadAllBytes(FileName);
newFile.ContentStream = new System.IO.MemoryStream(FileContent);
newFile.Url = System.IO.Path.GetFileName(FileName);
Microsoft.SharePoint.Client.List docLib = web.Lists.GetByTitle(DocumentLibrary);
Microsoft.SharePoint.Client.Folder uplFold = docLib.RootFolder.Folders.Add(CustomerFolder);
uplFold.Update();
Microsoft.SharePoint.Client.File uplFile = uplFold.Files.Add(newFile);
cContext.Load(docLib);
cContext.Load(uplFile);
cContext.ExecuteQuery();
}
So obviously the above is not working.
Speaking to a fellow from IT, he advised me to use API, but I have difficulties in finding a sample code online to upload a file to SharePoint using the user's current credentials.
Any advice?

Authentication in ADFS with Web Service

I have developed the test application in which I have added .asmx file for ADFS authentication, after authentication, it would redirect to my original already developed web application. the common code is shown below
var stsEndpoint = ConfigurationManager.AppSettings["EndPoint"];
var relayPartyUri = ConfigurationManager.AppSettings["RelayPartyUri"];
EndpointAddress epoint = new EndpointAddress(stsEndpoint);
using (var factory = new WSTrustChannelFactory(new UserNameWSTrustBinding(SecurityMode.TransportWithMessageCredential), epoint) { TrustVersion = TrustVersion.WSTrust13 })
{
if (factory.Credentials != null)
{
factory.Credentials.UserName.UserName = #"Domain\" + userName;
factory.Credentials.UserName.Password = password;
}
var rst = new RequestSecurityToken
{
RequestType = WSTrust13Constants.RequestTypes.Issue,
AppliesTo = new EndpointReference(relayPartyUri),
KeyType = WSTrust13Constants.KeyTypes.Bearer
};
var channel = factory.CreateChannel();
var token = channel.Issue(rst);
var genericToken = token as GenericXmlSecurityToken;
...
}
...
The line var token = channel.Issue(rst); throws error
Error is ID3082: The request scope is not valid or is unsupported
Also, I am not sure which URI I should use for RelyingPartyURI
the service URL which I am using for ADFS authentication. or
the URL of my already developed web application
Please help.

relayPartyUri is the unique identifier for your app.

Is this why a WCF SSL Secure Channel is faulting?

I'm supporting a project where we recently needed to apply a series of upgrades to a newer version of the .Net Framework. This has largely succeeded but for one final component that's been around for a very long time.
Our client uses InfoPath templates to populate information for other users to consume. Everything the templates need comes from a WCF web service we host. We set the web service call up with the following code.
private WSHttpBinding CreateBinding()
{
var wsHttpBinding = new WSHttpBinding();
wsHttpBinding.CloseTimeout = TimeSpan.FromMinutes(10);
wsHttpBinding.OpenTimeout = TimeSpan.FromMinutes(10);
wsHttpBinding.ReceiveTimeout = TimeSpan.FromMinutes(10);
wsHttpBinding.SendTimeout = TimeSpan.FromMinutes(10);
wsHttpBinding.BypassProxyOnLocal = false;
wsHttpBinding.TransactionFlow = false;
wsHttpBinding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
wsHttpBinding.MaxBufferPoolSize = 524288;
wsHttpBinding.MaxReceivedMessageSize = 2147483647;
wsHttpBinding.MessageEncoding = WSMessageEncoding.Text;
wsHttpBinding.TextEncoding = Encoding.UTF8;
wsHttpBinding.UseDefaultWebProxy = true;
wsHttpBinding.AllowCookies = false;
wsHttpBinding.ReaderQuotas.MaxDepth = 32;
wsHttpBinding.ReaderQuotas.MaxStringContentLength = 2147483647;
wsHttpBinding.ReaderQuotas.MaxArrayLength = 16384;
wsHttpBinding.ReaderQuotas.MaxBytesPerRead = 4096;
wsHttpBinding.ReaderQuotas.MaxNameTableCharCount = 16384;
wsHttpBinding.ReliableSession.Ordered = true;
wsHttpBinding.ReliableSession.InactivityTimeout = TimeSpan.FromMinutes(10);
wsHttpBinding.ReliableSession.Enabled = false;
wsHttpBinding.Security.Mode = SecurityMode.TransportWithMessageCredential;
wsHttpBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
wsHttpBinding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
wsHttpBinding.Security.Transport.Realm = string.Empty;
wsHttpBinding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
wsHttpBinding.Security.Message.NegotiateServiceCredential = false;
wsHttpBinding.Security.Message.AlgorithmSuite = SecurityAlgorithmSuite.Basic256;
return wsHttpBinding;
}
private EndpointAddress CreateEndPoint()
{
X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadOnly);
X509Certificate2 certificate = store.Certificates.Find(X509FindType.FindBySubjectName, "*.wildcard.address.foo", false)[0];
store.Close();
EndpointIdentity identity = EndpointIdentity.CreateX509CertificateIdentity(certificate);
string address = getWcfServiceUrl();
AddressHeader header = AddressHeader.CreateAddressHeader(address);
List<AddressHeader> headerList = new List<AddressHeader> { header };
Uri uri = new Uri(address);
var endpointAddress = new EndpointAddress(uri, identity, headerList.ToArray());
return endpointAddress;
}
}
This works fine and if we're testing it out, calls can be made successfully for all other intents and purposes. Except for one.
In one case we need to get information from a 3rd party resource. In that situation, our web service makes a separate call out to this 3rd party at an HTTPS address (passed in to the url parameter here:
private string requestURL(string url)
{
string toReturn = null;
Stream stream = null;
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = httpMethod;
stream = ((HttpWebResponse)request.GetResponse()).GetResponseStream();
StreamReader reader = new StreamReader(stream);
toReturn = reader.ReadToEnd();
}
catch(Exception e)
{
throw new Exception("Error with that service please try again: " + e.Message, e);
}
finally
{
if(stream != null)
{
stream.Close();
}
}
return toReturn;
}
In this case, the following error is returned:
The request was aborted: Could not create SSL/TLS secure channel.
My suspicion is that we're setting up a very specific set of constraints around the SSL connection between our local client (i.e. InfoPath) and the web service but the call from that web service to the 3rd party is not set up with any constraints beyond simply calling over HTTPS.
What should I be looking out for in trying to fix this issue?

WCF IMHO is particular about configuration at both ends and asks for things like transport credential specifically in the back and forth. I suspect you have no control of how the security is managed at the third party and can't change it, but your generic method to call all web services won't work because the configuration doesn't match.

How to upload a file to a document library in sharepoint?

I have a byte[] data and I want to upload it to sharepoint site using c#. I also want to pass credentials for it. Can anyone please guide me.
The code I tried is:
Uri destUri = new Uri("http://test.net/excel/docs/Forms/AllItems.aspx/");
WebRequest req = WebRequest.Create(destUri);
req.Method = "PUT";
req.Credentials = CredentialCache.DefaultCredentials;
using (req.GetRequestStream())
{
string destFilename = #"\\test.net\excel\docs\501.xls";
byte[] data = new byte[10];
System.IO.File.WriteAllBytes(destFilename, data);
}
ERROR:
Access Denied

Current user should have add permissions on this library
public void UploadFileToDocmentLibrary(Byte[] contentArray)
{
using (SPSite sharePointtopLevelSite = new SPSite("http://localhost"))
{
SPWeb websiteCollection = sharePointtopLevelSite.AllWebs["webName"];
websiteCollection.AllowUnsafeUpdates = true;
websiteCollection.Lists.IncludeRootFolder = true;
SPList docLibrary = websiteCollection.Lists["listName"];
SPFile file = websiteCollection.Files.Add(websiteCollection.Url.ToString() + "/" + docLibrary.Title.ToString() + "/" + "fileName.ext", contentArray);
file.Update();
}
}
If user without permissions should do it, use RunWithElevatedPrivileges statement

If I understood your requirements properly, you need to upload file into SharePoint On-Premise, right? There are several options on how to accomplish it.
Send file via HTTP POST using .NET
At least the following components could be utilized for that purpose:
HttpWebRequest
WebClient
HttpClient
Example
The example demonstrates how to upload file using WebClient.UploadFile Method:
public static void UploadFile(Uri targeUri, ICredentials credentials, string fileName)
{
using (var client = new WebClient())
{
client.Credentials = credentials;
//client.Headers.Add("X-FORMS_BASED_AUTH_ACCEPTED", "f");
var targetFileUri = targeUri + "/" + Path.GetFileName(fileName);
client.UploadFile(targetFileUri, "PUT", fileName);
}
}
Usage
var filePath = #"C:\Documents\SharePoint User Guide.docx";
var credentials = new NetworkCredential(userName, password, domain);
UploadFile(new Uri("https://contoso.sharepoint.com/documents"),credentials, filePath);
Using Microsoft SharePoint Server Object Model
using (var site = new SPSite(url))
{
using (var web = site.OpenWeb())
{
var list = web.Lists.TryGetList(listTitle);
var targetFolder = list.RootFolder;
var fileContent = System.IO.File.ReadAllBytes(fileName);
var fileUrl = Path.GetFileName(fileName);
targetFolder.Files.Add(fileUrl, fileContent);
}
}

{
var fi = new FileInfo(fileName);
var list = ctx.Web.Lists.GetByTitle(listTitle);

ctx.ExecuteQuery();
var fileUrl = String.Format("{0}/{1}", list.RootFolder.ServerRelativeUrl, fi.Name);
Microsoft.SharePoint.Client.File.SaveBinaryDirect(ctx, fileUrl, fs, true);
}
}

Get location of client machine using ip address

I am trying to get the location of client machine using ip address. Client can access the internet only if
he/she provide the proxy authenication.
Let us say client need to access the 'www.google.com' on the browser then immediately Authenication Required
prompt window open and then client enter his/her username and password. But it is possible the few users does
not required the provide the authenication in order to access internet.
This segment of code does not helped me...
string url = "http://freegeoip.net/xml/";
WebClient wc = new WebClient();
WebProxy proxyObj = new WebProxy("http://freegeoip.net/xml/");
proxyObj.Credentials = CredentialCache.DefaultCredentials;
Uri uri = new Uri(url);
MemoryStream ms = new MemoryStream(wc.DownloadData(uri));
XmlTextReader rdr = new XmlTextReader(url);
XmlDocument doc = new XmlDocument();
ms.Position = 0;
doc.Load(ms);
ms.Dispose();
In the above code if i add network credential instance with username, password and domain then it's work perfectly
Instead of providing the default net credential in code itself, I need to get the username and password from the users(client
machine).
My question is how to prompt the Authentication Required Window and get the username and password to load the download from url
I would be glad if someone throw light on this issue...
Edit: Somehow basic authentication window prompt and now i can get the username and password which can use for credential
try
{
var reg = HttpContext.Current.Request;
if (!String.IsNullOrEmpty(reg.Headers["Authorization"]))
{
var cred = System.Text.ASCIIEncoding.ASCII.GetString(Convert.FromBase64String(Request.Headers["Authorization"].Substring(6))).Split(':');
var user = new { Name = cred[0], Pass = cred[1] };
string url = "http://freegeoip.net/xml/";
WebClient wc = new WebClient();
WebProxy wProxy = new WebProxy();
ICredentials crd;
crd = new NetworkCredential("'" + cred[0] + "'", "'" + cred[1] + "'");
wProxy = new WebProxy("myproxy", true, null, crd);
wc.Proxy = wProxy;
Uri uri = new Uri(url);
string content = wc.DownloadString(uri);
}
else
{
try
{
//var reg = HttpContext.Current.Request;
if (String.IsNullOrEmpty(reg.Headers["Authorization"]))
{
var res = HttpContext.Current.Response;
res.StatusCode = 401;
res.AddHeader("WWW-Authenticate", "Basic realm = \"freegeoip\"");
//res.End();
}
}
catch (Exception ex)
{
}
}
}
catch(Exception ex)
{
}
But Still It throwing the "Unable to connect to the remote server"
