How do I add a salesforce community user using the API?

I've downloaded the API WSDL and added it to my C# project and have many successful integrations running throught it both bringing down and upserting data. I'm having a lot of trouble with creating community user accounts for our learning management system though.
I can't tell if I need to supply an account, or a contact, or a user type, and no matter what I try I end up with an error that doesn't lead me to a logical fix.
I think i'm closest with the below configuration, which is giving me this error: "You can't create a contact for this user because the org doesn't have the necessary permissions. Contact Salesforce Customer Support for help."
This is my C# code I'm trying to create a User account with:
public UpsertResponse UpsertLearningUser()
{
SFProd.User U = new SFProd.User();
U.Id = UserID;
U.Username = UserName;
U.Alias = TechCode;
U.CommunityNickname = FirstName + "." + LastName;
U.FirstName = FirstName;
U.LastName = LastName;
U.MiddleName = MiddleName;
U.Title = Title;
U.Department = Department;
U.Division = Division;
U.IsActive = Active;
U.IsActiveSpecified = true;
U.UserPermissionsChatterAnswersUser = true;
U.UserPermissionsChatterAnswersUserSpecified = true;
//U.UserPermissionsMobileUser = true;
//U.UserPermissionsMobileUserSpecified = true;
U.Phone = Phone;
U.EmployeeNumber = ADPNumber;
U.NS_Internal_ID__c = NSEmployeeID.ToString();
U.Employee_ID__c = double.Parse(EmployeeID.ToString());
U.Employee_ID__cSpecified = true;
U.Zone__c = Department;
U.Region__c = Division;
U.Certification_Level__c = CertificationLevel;
if (CertificationLevelDate != DateTime.Parse("1/1/1900"))
{
U.Certification_Level_Date__c = CertificationLevelDate;
U.Certification_Level_Date__cSpecified = true;
}
U.Country = Country;
U.State = State;
U.City = City;
U.PostalCode = PostalCode;
U.Street = Street;
U.Email = Email;
U.TimeZoneSidKey = "America/Chicago";
U.EmailEncodingKey = "ISO-8859-1";
U.ProfileId = "00ef10000016tfvAAA";
U.LanguageLocaleKey = "en_US";
U.ContactId = ContactID;
List<SFProd.sObject> Objs = new List<SFProd.sObject>();
Objs.Add(U);
return new UpsertResponse(SFConnection.RunUpsert("Username", Objs)[0], UserID);
}
Has anyone else done this sucessfully? or have any idea what I'm doing wrong?

There is a special function for creating external users. Try a variation of the CreateExternalUser() function: https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_sites.htm

Validation error when attempting to SaveChanges to table

I am rather new to the whole programming with C# and I stumbled upon a small problem that I just cannot solve.
I start up the software the code below is programmed into and it is working well until it reaches the SaveChanges call and it throws an error:
Validation failed for one or more entities. See 'EntityValidationErrors' property for more details.
I have already attempted to inspect EntityValidationErrors, but it doesn't want to show me any errors at all. So I am turning to you all to find some answers.

If you need any further information, just tell me and I will provide it. The main thing I want is to get this working and this is not the only code giving me this problem, but if this one can be solved, then maybe the other ones can be solved the same way.

This error is caused when you are trying to add invalid data to your database table.
e.g. you are adding string of 100 chars to the table column but in table definition your column has maxlength of 50. in that case value you are adding is invalid as per the column definitions and this error occur.
you should log what properties are causing the error. for that you can use below code:
catch (System.Data.Entity.Validation.DbEntityValidationException ex)
{
Logger.WriteError("{0}{1}Validation errors:{1}{2}", ex, Environment.NewLine, ex.EntityValidationErrors.Select(e => string.Join(Environment.NewLine, e.ValidationErrors.Select(v => string.Format("{0} - {1}", v.PropertyName, v.ErrorMessage)))));
throw;
}

You can catch these errors easily ,using the watch window, without writing much code.
Kindly find the very good solution in the following link

Getting password from mongodb c#

I am trying to create a login method and I need to get a password from the corresponding user. This is my database layer code:
public int loginUser(string userName, string pass)
{
int result = 0;
var credentials = MongoCredential.CreateMongoCRCredential("SearchForKnowledge", userName, pass);
var settings = new MongoClientSettings
{
Credentials = new[] { credentials }
};
try
{
var mongoClient = new MongoClient(settings);
var database = mongoClient.GetDatabase("SearchForKnowledge");
var coll = database.GetCollection<BsonDocument>("Users");
var filter = Builders<BsonDocument>.Filter.Eq("userName", userName);
var query = coll.Find(filter);
//??????????
}
catch (Exception ex) {
result = 0;
}
return result;
}
as you can see if the login is success im trying to return 1 and if it fails, 0 (for redirecting purposes). I am struggling to check if the username matches password set to it. At the moment I just made a filter, passed it to the method Find and im dead stuck at this point. How do I return that user's password from mongodb and compare it to the one passed as a parameter?

Try something like this:
public int loginUser(string userName, string pass)
{
int result = 0;
//Here you use credentials for the connection, not the one passed
//to the method:
var credentials = MongoCredential.CreateMongoCRCredential("SearchForKnowledge", connectionUsername, connectionPass);
var settings = new MongoClientSettings
{
Credentials = new[] { credentials }
};
try
{
var mongoClient = new MongoClient(settings);
var database = mongoClient.GetDatabase("SearchForKnowledge");
var coll = database.GetCollection<BsonDocument>("Users");
var filter = Builders<BsonDocument>.Filter.Eq("userName", userName);
var result = await coll.Find(filter).ToListAsync().First();
if(result["Password"] == pass)
{
result = 1;
}
}
catch (Exception ex) {
result = 0;
}
return result;

Controller is returning blank View in my website

public async Task<IActionResult> Contact1()
{
if (Convert.ToBoolean(HttpContext.Session.GetString("login")))
{
var pass = new ContactViewModel();
var username = HttpContext.Session.GetString("username");
Program.readname(HttpContext.Session.GetString("username"));
var names = HttpContext.Session.GetString("studentnames");
var obj1 = JsonConvert.DeserializeObject<Program.Data>(names);
if (Program.datecheck(username, DateTime.Today.Date))
{
try{
var handler = new HttpClientHandler { Credentials = new NetworkCredential(user, password) };
using (var client = Program.CreateHttpClient(handler, user, database3))
{
string check = username + Convert.ToString(DateTime.Today.Date);
var readresponse = client.GetStringAsync(check).Result;
var obj2 = JsonConvert.DeserializeObject<Program.Data>(readresponse);
}
catch(Exception ee)
{ ViewBag.m6 = ee.Message; ViewBag.attendance = "Attendace is not take yet";}
}
pass.studentattend = obj2.studentattend1;
}
}
else { ViewBag.attendance = "Attendace is not take yet"; }
pass.studentname = obj1.studentname1;
pass.studentrollno = obj1.studentrollno1;
pass.date = DateTime.Today.Date;
HttpContext.Session.SetInt32("classselect", 1);
ViewData["Message"] = "Student Attendance of Class: " + HttpContext.Session.GetString("classname1");
ViewBag.Login = HttpContext.Session.GetString("login");
ViewBag.name = HttpContext.Session.GetString("name");
ViewBag.classname1 = HttpContext.Session.GetString("classname1");
ViewBag.classname2 = HttpContext.Session.GetString("classname2");
ViewBag.classname3 = HttpContext.Session.GetString("classname3");
ViewBag.classname4 = HttpContext.Session.GetString("classname4");
return View("/Views/Home/Contact.cshtml", pass);
}
else
{
ViewData["Message"] = "Please Login First!!";
return View("/Views/Home/Login.cshtml");
}
}
The above code is runnig well in my local ISS server but when i run this on bluemix then i am getting blank page. I tried to find out the problem and get to the conclusion that if the control does not enter in the if part of that code:
if (Program.datecheck(username, DateTime.Today.Date))
{
var handler = new HttpClientHandler { Credentials = new NetworkCredential(user, password) };
using (var client = Program.CreateHttpClient(handler, user, database3))
{
string check = username + Convert.ToString(DateTime.Today.Date);
var readresponse = client.GetStringAsync(check).Result;
var obj2 = JsonConvert.DeserializeObject<Program.Data>(readresponse);
pass.studentattend = obj2.studentattend1;
}
}
else { ViewBag.attendance = "Attendace is not take yet"; }
then it will run fine.I am unable to find what is wrong in that query.
