I've having difficulty following this guide
http://dotnetbyexample.blogspot.co.uk/2011/03/sharepoint-client-object-model-sites.html
I've created the helper class as advised:
namespace TestSharepoint
{
public class SharepointHelper
{
private ClientContext clientContext;
private Web rootWeb;
public SharepointHelper(string url, string username, string password)
{
clientContext = new ClientContext(url);
var credentials = new NetworkCredential(username, password, "oshirowanen.com");
clientContext.Credentials = credentials;
rootWeb = clientContext.Web;
clientContext.Load(rootWeb);
}
}
}
However, I do not want to create another site, as I already have a site, so I wanted to test the next part by retrieving the existing sites title:
public Web GetWebByTitle(string siteTitle)
{
var query = clientContext.LoadQuery(
rootWeb.Webs.Where(p => p.Title == siteTitle));
clientContext.ExecuteQuery();
return query.FirstOrDefault();
}
and added this to the form load event:
var sh = new SharepointHelper("https://sharepoint.oshirowanen.com/sites/oshirodev/", "sharepoint_admin_user", "sharepoint_admin_password");
var w = sh.GetWebByTitle("Oshirowanen SharePoint");
Console.WriteLine(w.Title);
What I am getting confused about is, why I am typing in the title of the site which I want to receive the title of??? So I think I am not using this properly?
The error I get is:
An unhandled exception of type 'System.NullReferenceException' occurred in SharePointProgramming.exe
Additional information: Object reference not set to an instance of an object.
Any idea what I am doing wrong?
The username and password I have used has full SharePoint privileges.
I am using Visual Studio 2013, C#, .NET 4.0, and SharePoint 2010.
To fetch the title of the site your just need the value of the variable web.title.
namespace TestSharepoint
{
public class SharepointHelper
{
private ClientContext clientContext;
private Web rootWeb;
public SharepointHelper(string url, string username, string password)
{
clientContext = new ClientContext(url);
var credentials = new NetworkCredential(username, password, "oshirowanen.com");
clientContext.Credentials = credentials;
rootWeb = clientContext.Web;
clientContext.Load(rootWeb,web=>web.title);
clientContent.ExecuteQuery();
string siteTitle=web.title;
}
}
}

I'm struggeling to understand how to use SharePoint CSOM to add a user as Site Collection Admin.
So far this code works for a Global Admin to add a user as Site Colleciton Admin, eventhough the Global Admin is not included as Site Admin.
I've tried to run the code as normal user which is only Site Collection Admin, to add another user as Site Colleciton Admin. But then I get some errors:
If I use the SharePoint Admin URL to get the Access Token, then the code crash on row #48 as 401 "Unauthorized"
If I use the Site Collection URL to get the Access Token, I get error when trying to get the acces token saying that Site is doesn't exist on the environment.
If I use the root site URL ("https://domain-admin.sharepoint.com/) to get the Access Token, then the code crash on row #51 as 401 "Unauthorized".
I'm using the PnP.PowerShell code as reference: https://github.com/pnp/powershell/blob/dev/src/Commands/Admin/SetTenantSite.cs#L547-L574
And my process is pretty much the same as here: MSAL AD token not valid with SharePoint Online CSOM
But I don't have clear if it's a issue of access token or the CSOM commands I use.
Does anyone has any idea how to move forward?
btw, I guess if I use the Global Admin account I only need to use tenant.SetSiteAdmin(siteCollection, userEmail, true);. I read somewhere that even for global admin I need EnsureUser(userEmail);, but so far the code seems working without it.
using Microsoft.Identity.Client;
using Microsoft.SharePoint.Client;
namespace ScriptTester
{
internal class Program
{
static async Task Main(string[] args)
{
await AddUserAdmin();
}
public static async Task AddUserAdmin()

string siteRoot = "https://domain.sharepoint.com/";
string siteCollection = "https://domain.sharepoint.com/sites/SiteName/";
string userEmail = "_email";
string accessToken = await GetAccessToken(siteRoot);
using (var context = new Microsoft.SharePoint.Client.ClientContext(siteRoot))
{
context.ExecutingWebRequest += (sender, e) =>
{
e.WebRequestExecutor.RequestHeaders["Authorization"] = "Bearer " + accessToken;
};
var tenant = new Microsoft.Online.SharePoint.TenantAdministration.Tenant(context);
try
{
addLog("Try using tenant context");
tenant.SetSiteAdmin(siteCollection, userEmail, true);
tenant.Context.ExecuteQueryRetry();
}
catch (Exception ex)
{
addLog("Failed using Tenant context");
addLog(ex.Message);
using (var site = tenant.Context.Clone(siteCollection))
{
var user = site.Web.EnsureUser(userEmail);
user.Update();
user.IsSiteAdmin= true;
site.Load(user);
site.ExecuteQueryRetry();
tenant.SetSiteAdmin(siteCollection, userEmail, true);
tenant.Context.ExecuteQueryRetry();
}
}
}

I will recommend you to use PnP Core component to access site collection and add admin. Please refer to the following code
string siteUrl = "https://xxx.sharepoint.com/";
string userName = "xxxx#xxx.onmicrosoft.com";
string password = "*******";
AuthenticationManager authManager = new AuthenticationManager();
try
{
using (var clientContext = authManager.GetSharePointOnlineAuthenticatedContextTenant(siteUrl, userName, password))
{
List<UserEntity> admins = new List<UserEntity>();
UserEntity admin = new UserEntity();
admin.LoginName = "nirmal";
admins.Add(admin);
clientContext.Site.RootWeb.AddAdministrators(admins, true);
Console.WriteLine("User added as Site Collection Admin");
Console.ReadKey();
}
}
catch (Exception ex)
{
Console.WriteLine("Error Message: " + ex.Message);
Console.ReadKey();
}
I have signed up for the Office 365 Developer Edition with Microsoft 365 E5 Developer (without Windows and Audio Conferencing). I am writing codes to connect to the Sharepoint of developer domain. Following are my codes:
public static String GetList( ICredentials credentials)
{
var authManager = new OfficeDevPnP.Core.AuthenticationManager();
using (ClientContext clientContext =
authManager.GetWebLoginClientContext("https://xxx.sharepoint.com"))
{
clientContext.Credentials = credentials;
Web web = clientContext.Web;
clientContext.Load(web,
webSite => webSite.Title);
clientContext.ExecuteQuery();
return web.Title;
}
}
public string callSharepoint()
{
const string userName = "Username#domain.onmicrosoft.com";
const string password = "xxxx";
var securePassword = new SecureString();
foreach (var c in password)
{
securePassword.AppendChar(c);
}
var credentials = new SharePointOnlineCredentials(userName, securePassword);
var list = GetList(credentials);
return list.ToString();
}
While running, it first asks to enter Microsoft Office credentials, and then it does verification by sending code to contact number and then after verification is completed it throws an Exception on Line
clientContext.ExecuteQuery(). The Exception is as follow:
Microsoft.SharePoint.Client.IdcrlException: 'The sign-in name or password does not match one in the Microsoft account system.'
The credentials I am using is of Admin Account with role Global Administrator. I also tried to add new user account in that Active Directory and tried that credentials but still got the same exception on the same place.
I even try to remove Pnp Authorization, Enable and disable Multi factor Authorization, but no success. However, I can successfully log in into the Sharepoint site on browser by using exactly same credentials.
What I think is, there is most likely a problem in the setup which I did while setting office account developer subscription. And maybe nothing is wrong with the code because I used the same codes to log in to my organization's Sharepoint and it works perfectly fine. Maybe I need something else to be configured in my developer's Office Account.
Please let me know if anyone already has some knowledge about this problem.
You have init the credential so you could use it directly, if issue exists, should be related to your user account or license.
public static String GetList(ICredentials credentials)
{
//var authManager = new OfficeDevPnP.Core.AuthenticationManager();
//using (ClientContext clientContext =
//authManager.GetWebLoginClientContext("https://xxx.sharepoint.com/sites/lee"))
//{
//}
using (ClientContext clientContext = new ClientContext("https://xxx.sharepoint.com/sites/lee"))
{
clientContext.Credentials = credentials;
Web web = clientContext.Web;
clientContext.Load(web,
webSite => webSite.Title);
clientContext.ExecuteQuery();
return web.Title;
}
}
public string callSharepoint()
{
const string userName = "user#xxx.onmicrosoft.com";
const string password = "password";
var securePassword = new SecureString();
foreach (var c in password)
{
securePassword.AppendChar(c);
}
var credentials = new SharePointOnlineCredentials(userName, securePassword);
var list = GetList(credentials);
return list.ToString();
}
Ok I found the solution.
That is I don't need this line of code:
clientContext.Credentials = credentials;
Since MFA is enabled, so when I logged in via Pnp Authenticator, it should use that user account. Instead of the one which is passed via SharePointOnlineCredentials.
I am simply getting some users from SharePoint using CSOM using the below method. This has always worked for me and I've had no issues.
All of a sudden, when I try calling this method today it fails with this error
The sign-in name or password does not match one in the Microsoft account system.

But it only fails after publishing to Azure.
I have logged the username and password being used to the Azure applications streams, and they are definitely correct, and the same ones being used when debugging on my machine.
How is this possible? Am I going crazy?
Constructor
public SPClient(string url)
{
baseUrl = url;
var userName = ConfigurationManager.ConnectionStrings["SPsvcUsername"].ConnectionString;
var password = ConfigurationManager.ConnectionStrings["SPsvcPassword"].ConnectionString;
Trace.TraceInformation(userName);
Trace.TraceInformation(password);
var securePassword = new SecureString();
foreach (var c in password)
{
securePassword.AppendChar(c);
}
credentials = new SharePointOnlineCredentials(userName, securePassword);
}
Get Users method
public IEnumerable<SharePointUser> GetAllUsers()
{
var spUsers = new List<SharePointUser>();
using (var clientContext = new ClientContext(baseUrl))
{
clientContext.Credentials = credentials;
var web = clientContext.Web;
var list = clientContext.Web.SiteUserInfoList;
var users = list.GetItems(new CamlQuery());
clientContext.Load(users, includes => includes.Include(
f => f["GUID"],
f => f["FirstName"],
f => f["LastName"],
f => f["UserName"],
f => f["Picture"],
f => f.DisplayName));
clientContext.ExecuteQuery();
foreach (var user in users)
{
var imagePath = (FieldUrlValue)user.FieldValues["Picture"];
spUsers.Add(new SharePointUser()
{
FirstName = (user.FieldValues["FirstName"] is string firstName) ? firstName : string.Empty,
LastName = (user.FieldValues["LastName"] is string lastName) ? lastName : string.Empty,
UserName = (user.FieldValues["UserName"] is string userName) ? userName.ToLower() : string.Empty,
ImagePath = (user.FieldValues["Picture"] is FieldUrl pictureUrl) ? pictureUrl.ToString() : string.Empty,
DisplayName = user.DisplayName
});
}
}
return spUsers;
}
Since the credentials are correct, it may be that Multi-Factor Authentication is enabled and a policy may be triggering it for this account. If that is the case, you could disable MFA for that specific account.
Also, the AuthenticationManager class that is part of the PnP Core library may be beneficial as it is helpful for various authentication scenarios.
I have the MS Project Online account at sharepoint.com and I need to authenticate from client C# code to PSI services to get list of projects.
Server has Forms based authentication. I am trying to login via next code:
SvcLoginForms.LoginForms loginform = new SvcLoginForms.LoginForms();
loginform.Credentials = new NetworkCredential("admin#myserver.onmicrosoft.com", "password");
loginform.Url = "https://myserver.sharepoint.com/sites/pwa/_vti_bin/PSI/Project.asmx";
loginform.Login("admin#myserver.onmicrosoft.com", "password");
When I am executing loginform.Login I am getting SoapException with message: "Value cannot be null. Parameter name: account". Inner exception xml is:
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">Value cannot be null.
Parameter name: account
What I am doing wrong?
You can use:
new SharePointOnlineCredentials(username, secpassword);
instead of
new NetworkCredential("admin#myserver.onmicrosoft.com", "password");
First: Install required Client SDK
SharePoint Client SDK :
http://www.microsoft.com/en-au/download/details.aspx?id=35585
Project 2013 SDK:
http://www.microsoft.com/en-au/download/details.aspx?id=30435
Second: add the reference to your project
Microsoft.SharePoint.Client.dll
Microsoft.SharePoint.Client.Runtime.dll
Microsoft.ProjectServer.Client.dll
You can find the dlls in %programfiles%\Common Files\microsoft shared\Web Server Extensions\15\ISAPI
and %programfiles(x86)%\Microsoft SDKs\Project 2013\REDIST
Here is sample code:
using System;
using System.Security;
using Microsoft.ProjectServer.Client;
using Microsoft.SharePoint.Client;
public class Program
{
private const string pwaPath = "https://[yoursitehere].sharepoint.com/sites/pwa";
private const string username ="[username]";
private const string password = "[password]";
static void Main(string[] args)
{
SecureString secpassword = new SecureString();
foreach (char c in password.ToCharArray()) secpassword.AppendChar(c);
ProjectContext pc = new ProjectContext(pwaPath);
pc.Credentials = new SharePointOnlineCredentials(username, secpassword);
//now you can query
pc.Load(pc.Projects);
pc.ExecuteQuery();
foreach(var p in pc.Projects)
{
Console.WriteLine(p.Name);
}
//Or Create a new project
ProjectCreationInformation newProj = new ProjectCreationInformation() {
Id = Guid.NewGuid(),
Name = "[your project name]",
Start = DateTime.Today.Date
};
PublishedProject newPublishedProj = pc.Projects.Add(newProj);
QueueJob qJob = pc.Projects.Update();
JobState jobState = pc.WaitForQueue(qJob,/*timeout for wait*/ 10);
}
}
Authentication to Project Online PSI services is described in this excellent article: http://www.umtsoftware.com/blog/how-to-project-online-psi/
I have a client who is implementing customer portals in Sharepoint 2013 Online. The current program distributes documents to the customers by mail. Now we have to upload the documents to the customer portal.
I try to use the copy webservice in sharepoint. I created a test project and added the webservice as Web Reference and wrote the following testcode:
static void Main(string[] args)
{
string baseUrl = "https://mycustomer.sharepoint.com/sites/";
string customer = "customerportalname";
string serviceUrl = "/_vti_bin/copy.asmx";
string destinationDirectory = "/folder/";
string fileName = "uploaded.xml";
string username = "username#outlook.com";
string password = "password";
XmlDocument xmlDocument = new XmlDocument();
xmlDocument.LoadXml("<fiets><onderdeel>voorwiel</onderdeel><onderdeel>achterwiel</onderdeel><onderdeel>trappers</onderdeel><onderdeel>stuur</onderdeel><onderdeel>frame</onderdeel></fiets>");
byte[] xmlByteArray;
using (MemoryStream memoryStream = new MemoryStream())
{
xmlDocument.Save(memoryStream);
xmlByteArray = memoryStream.ToArray();
}
string destinationUrl = string.Format("{0}{1}{2}{3}", baseUrl, customer, destinationDirectory, fileName);
string[] destinationUrlArray = new string[] { destinationUrl };
FieldInformation fieldInfo = new FieldInformation();
FieldInformation[] fields = { fieldInfo };
CopyResult[] resultsArray;
using (Copy copyService = new Copy())
{
copyService.PreAuthenticate = true;
copyService.Credentials = new NetworkCredential(username, password);
copyService.Url = string.Format("{0}{1}", baseUrl, serviceUrl);
copyService.Timeout = 600000;
uint documentId = copyService.CopyIntoItems(destinationUrl , destinationUrlArray, fields, xmlByteArray, out resultsArray);
}
}
When I execute the code I recieve the following error:
The request failed with the error message:
--
<html><head><title>Object moved</title></head><body>
<h2>Object moved to here.</h2>
</body></html>
--
It looks like I'm not authenticated and get redirected. The credentials however are correct.
Does anyone have an idea? Thanks in advance!
UPDATE
To be able to connect to SharePoint 2013 Online you have to attach the Office 365 authentication cookies as explained in this post.
My problem however is that there is also an ADFS involved. How can I autheticate against the ADFS?
This error most probably occurs due to incorrect authentication mode.
Since SharePoint Online (SPO) uses claims-based authentication, NetworkCredential Class can not be utilized for authentication in SPO.
In order to perform the authentication against the ADFS in SPO you could utilize SharePointOnlineCredentials class from SharePoint Online Client Components SDK.
How to authenticate SharePoint Web Services in SharePoint Online (SPO)
The following example demonstrates how to retrieve authentication cookies:
private static CookieContainer GetAuthCookies(Uri webUri, string userName, string password)
{
var securePassword = new SecureString();
foreach (var c in password) { securePassword.AppendChar(c); }
var credentials = new SharePointOnlineCredentials(userName, securePassword);
var authCookie = credentials.GetAuthenticationCookie(webUri);
var cookieContainer = new CookieContainer();
cookieContainer.SetCookies(webUri, authCookie);
return cookieContainer;
}
Example
string sourceUrl = "https://contoso.sharepoint.com/Documents/SharePoint User Guide.docx";
string destinationUrl = "https://contoso.sharepoint.com/Documents/SharePoint User Guide 2013.docx";
FieldInformation[] fieldInfos;
CopyResult[] result;
byte[] fileContent;
using(var proxyCopy = new Copy())
{
proxyCopy.Url = webUri + "/_vti_bin/Copy.asmx";
proxyCopy.CookieContainer = GetAuthCookies(webUri, userName, password);
proxyCopy.GetItem(sourceUrl,out fieldInfos,out fileContent);
proxyCopy.CopyIntoItems(sourceUrl,new []{ destinationUrl}, fieldInfos, fileContent, out result);
}

In my case (on premise) i have that error. when i changed at iis SharePoint authentication for web application , and disable "Forms Authentication". Now, i can´t enter to SharePoint by UI, but the Web Service works... So I have revert and I have been looking and...
[Paul stork] The Web Application for this site is running in Classic Mode rather than Claims mode. This can happen if you create the web app using Powershell or upgrade from 2010. You can use PowerShell to change it.
http://technet.microsoft.com/en-us/library/gg251985.aspx
I have tried the Web Service in another new application created by UI in Central Administration (in same farm) and it had worked. The problem was the web application.

Extend your mixed authentication web application, and create a zone just for Windows Authentication, then change the Web Reference URL in the properties of your web service, to use that extended URL and port. You should have no issues of this kind anymore.
