how to access session data from layout c#

Good day,
I am trying to pass a user last name into my layout.
In my home index I get my user last name and assign it to my session.
var userId = User.Identity.GetUserId();
var usuerInDb = _user.GetUsuario(userId);
HttpContext.Session["LastName"] = usuerInDb .LastName;
//More code here ....
return view();
What I would like to do is to acess "LastName" from my session and assign it to my layout in some way like the following
//Layout
//....more code
Hello #session["LastName"]
How should I do it? I also accept other approaches.
Thanks

I would suggest using User Claims, to avoid bloating the session with a lot of user information.

if are usin MVC you can use TempData["LastName"]
replace
HttpContext.Session["LastName"] = usuerInDb .LastName;
to
TempData["LastName"] = = usuerInDb .LastName;
In view..
Hello TempData["LastName"]

Updating MetaData on Connected account fails

I am using stripe connect(destination payment) with the help of stripe.net library from Jaymedavis.
The problem that I am facing is that I am not able to retrieve the destination payment ID to update the metadata in the connected account. The following line returns a null preventing me from updating meta data on the connected account. But the strange thing is that when I log in to the dashboard the destination payment ID exists. I am not sure why I am not able to retreive it in code.
Is the charge creation asynchronous?. I am not sure. Stripe's connect documentation does not help either. The following line returns a null. My code is down below. Seeking help.
String deschargeID = result.Transfer.DestinationPayment;
Here is the code that I am using
var service = new StripeChargeService(ZambreroSecretKey);
var result = (Stripe.StripeCharge) null;
try {
result = service.Create(newCharge);
if (result.Paid) {
//get the chargeID on the newgen account and update the metadata.
//Returns null even though it exists in the dashboard
String deschargeID = result.Transfer.DestinationPayment;
var chargeService = new StripeChargeService(newgenSecretKey);
StripeCharge charge = chargeService.Get(deschargeID);
charge.Metadata = myDict;
Response.Redirect("PgeCustSuccess.aspx?OrderID=" + OrderID);
}
} catch (StripeException stripeException) {
Debug.WriteLine(stripeException.Message);
stripe.Text = stripeException.Message;
}

The charge object's transfer attribute is not expanded by default, meaning it's just a string with the ID of the transfer object ("tr_..."), not a full transfer object.
According to Stripe.net's documentation, you can expand the transfer attribute by adding this line:
service.ExpandTransfer = True
before sending the charge creation request.

Cache player with GameSparks and Unity

I am new to gamesparks, but so far I have set up a login/register function, which works like it should, but... How do I ensure that the user don't have to login next time he or she opens the app?
I found this in which I read that I can just run this:
GameSparkssApi.isAuthenticated().
First off all, in all other tutorials it states that it should be: GameSparks.Api.xxxx. Even when trying this I do not find isAuthenticated() anywhere.
GameSparks.Api.isAuthenticated();
I am hoping that someone can cast some light on this.

You can use Device Authentication for this purpose. This method of auth sets an access token for the device you are on. This token is stored and the client and gotten in the request. these requests are structured like so:
new GameSparks.Api.Requests.DeviceAuthenticationRequest()
.SetDeviceId(deviceId)
.SetDeviceModel(deviceModel)
.SetDeviceName(deviceName)
.SetDeviceOS(deviceOS)
.SetDeviceType(deviceType)
.SetDisplayName(displayName)
.SetOperatingSystem(operatingSystem)
.SetSegments(segments)
.Send((response) => {
string authToken = response.AuthToken;
string displayName = response.DisplayName;
bool? newPlayer = response.NewPlayer;
GSData scriptData = response.ScriptData;
var switchSummary = response.SwitchSummary;
string userId = response.UserId;
});
You can find more on this method in our documentation: https://api.gamesparks.net/#deviceauthenticationrequest

How to store login user id in asp.net?

i am new to asp.net. my question is that how one can save login userid in asp.net webform?
code i am writing in asp.net webform is:
foreach (var s in db.Users)
{
if (tbUserName.Text==s.user_name && tbPassword.Text == s.user_password)
{
if (string.IsNullOrEmpty(Request.QueryString["ReturnUrl"]))
{
FormsAuthentication.SetAuthCookie(tbUserName.Text, false);
Response.Redirect("~/");
}
else
{
FormsAuthentication.RedirectFromLoginPage(tbUserName.Text, false);
}
flag = 1;
break;
}
else
flag=0;
}
if(flag==0)
{
tbUserName.ErrorText = "Invalid user";
tbUserName.IsValid = false;
}
}

As Tim said, you can get the authenticated user with
User.Identity.Name
You can also get the AuthenticationType and IsAuthenticated properties from the same object.
A suggestion would be to NOT query your DB for all of the users and then loop through them for the correct one. Based off of the user input, you should query the db for the one and only user which matches the form post.
Based off of what you wrote, it looks like the passwords are in clear text and not encrypted, which is a huge security issue. Being new to .Net, take a look at the .Net Membership Providers or SimpleMembership or a comparable pattern.
Good luck!

I would suggest you look at using the Session object to store the user ID. A Session will be available throughout that user's session on the site. Thus, you can call Session anywhere in your site's code to reference that user ID.
For example, to store the id, simply do this, pretend we're in Page_Load()
Session["UserId"] = userID // Or wherever you get the ID from.
then in your code behind, you can do this:
string userId = Session["UserId"]
If the user ID is a number, say an int, then you will need to cast the userID:
int userId = 0;
int.TryParse(Session["UserID"], out userID)

Setting up 3DCart API with a C# App

I have been trying to create an application to go through our database at a set interval and update/add any new items to 3DCarts database. Their code example uses soap in an xml file to send 1 request per call. So I need to to be able to generate the xml I need with the items information on the fly before sending it. I have done hardly anything with XML files like this and cannot figure out how to create the chunk of code I need and send it. One method that has been suggested is create a file but still executing has been a problem and would be very inefficient for a large number of items. Here is what I have so far
sqlStatement = "SELECT * FROM products WHERE name = '" + Convert.ToString(reader.GetValue(0)) + "'";
ServiceReferenceCart.cartAPIAdvancedSoapClient bcsClient = new ServiceReferenceCart.cartAPIAdvancedSoapClient();
ServiceReferenceCart.runQueryResponse bcsResponse = new ServiceReferenceCart.runQueryResponse();
bcsClient.runQuery(storeUrl, userKey, sqlStatement, callBackURL);
string result = Convert.ToString(bcsResponse);
listBox1.Items.Add(result);
EDIT: Changed from sample code block to current code block as I got a service reference setup finally. They provide no details though for using the functions in the reference. With this bcsResponse is just a blank, when I try adding .Body I have the same result but when I add .runQuery to the .Body I get a "Object reference not set to an instance of an object." error. As I have said I have not messed with service references before.
I hope I have explained well enough I just really have not worked with this kind of stuff before and it has become extremely frustrating.
Thank you in advance for any assistance.

I actually ended up figuring this out after playing around with it. Here is what I did to get the reference to work. This may have been easy for anyone who have used the references before but I have not and have decided to post this in case anyone else has this problem. The SQL can be SELECT, ADD, UPDATE and DELETE statements this was to see if the sku was listed before updating/adding.
//Will be using these multiple times so a variable makes more sense
// DO NOT include http:// in the url, also id is not shown in their
//database layout pdf they will give but it is the sku/product number
string sqlStatement = "SELECT id FROM products WHERE id = '" + Convert.ToString(reader.GetValue(0)) + "')))";
string userKey = "YourKeyHere";
string storeUrl = "YourStoresURLHere";
// Setting up instances from the 3DCart API
cartAPIAdvancedSoapClient bcsClient = new cartAPIAdvancedSoapClient();
runQueryRequest bcsRequest = new runQueryRequest();
runQueryResponse bcsResponse = new runQueryResponse();
runQueryResponseBody bcsRespBod = new runQueryResponseBody();
runQueryRequestBody bcsReqBod = new runQueryRequestBody();
//assigning required variables to the requests body
bcsReqBod.storeUrl = storeUrl;
bcsReqBod.sqlStatement = sqlStatement;
bcsReqBod.userKey = userKey;
//assigning the body to the request
bcsRequest.Body = bcsReqBod;
//Setting the response body to be the result
bcsRespBod.runQueryResult = bcsClient.runQuery(bcsReqBod.storeUrl, bcsReqBod.userKey, bcsReqBod.sqlStatement, bcsReqBod.callBackURL );
bcsResponse.Body = bcsRespBod;
//adding the result to a string
string result = bcsResponse.Body.runQueryResult.Value;
//displaying the string, this for me was more of a test
listBox1.Items.Add(result);
You will also need to activate the Advanced API on your shop as you may notice there is no actual option as the pdf's say, you need to go to their store and purchase(its free) and wait for them to activate it. This took about 2 hrs for us.
