I am attempting to build a blog based on a tutorial from VS 2010, and using VS 2013 I am getting errors. Any help would be appreciated. My Foreach statement will not execute.. I am getting an error stating Foreach statement cannot operate on variables of type 'blog.Models.Tag' because blog.Models.Tag does not contain a public definition for Get Enumerator...

Foreach can only be done on a collection implementing the GetEnumerator, because it uses this function to get the "next" item to foreach on. Apparently this function is not present.

I want to check each page values from the API and against the values to change the color of the map marker.
This is my API: http://194.141.118.43:3001/?id=0 where id is from 0 to 16
I want:
if from ?id=0 AL = 1 the marker should be green
if from ?id=0 AL = 2 the marker should be yellow
if from ?id=0 AL = 3 the marker should be orange
if from ?id=0 AL = 4 the marker should be red
So I want to check for all 17 stations (from ?id=0 to ?id=16)
I am currently checking the property Alertlevelwebsite in this method with this API: http://194.141.118.43:3001/stations, But now I have to check all the values from this address for each pin and I have to put a color for the largest value for each pin.
http://194.141.118.43:3001/?id=0 (from 0 to 16)
I use this example from xamarin.forms.maps - https://learn.microsoft.com/en-us/samples/xamarin/xamarin-forms-samples/workingwithmaps/ and in CustomMapRenderer class I try to change the colors in this method:
protected override MKAnnotationView GetViewForAnnotation(MKMapView mapView, IMKAnnotation annotation)
{
MKAnnotationView annotationView = null;
if (annotation is MKUserLocation)
return null;
var customPin = GetCustomPin(annotation as MKPointAnnotation);
//Get Value
c_annotation = annotation;
if (customPin == null)
{
throw new Exception("Custom pin not found");
}
annotationView = mapView.DequeueReusableAnnotation(customPin.Name);
if (annotationView == null)
{
annotationView = new CustomMKAnnotationView(annotation, customPin.Name);
annotationView.CalloutOffset = new CGPoint(0, 0);
((CustomMKAnnotationView)annotationView).Name = customPin.Name;
((CustomMKAnnotationView)annotationView).Url = customPin.Url;
((CustomMKAnnotationView)annotationView).Address = customPin.Address;
//Add First Line
((CustomMKAnnotationView)annotationView).AlertLevel = customPin.AlertLevel;
if (customPin.AlertLevel == 1)
{
annotationView.Image = UIImage.FromFile("green.png");
}
else if (customPin.AlertLevel == 2)
{
annotationView.Image = UIImage.FromFile("yellow.png");
}
else if (customPin.AlertLevel == 3)
{
annotationView.Image = UIImage.FromFile("orange.png");
}
else if (customPin.AlertLevel == 4)
{
annotationView.Image = UIImage.FromFile("red.png");
}
//Add Second Line
((CustomMKAnnotationView)annotationView).CodeNum = customPin.CodeNum;
((CustomMKAnnotationView)annotationView).MapCode = customPin.MapCode;
//Here I add the RequestUri for stations
string GenerateRequestUriStations(string endpoint)
{
string requestUri = endpoint;
requestUri += $"stations";
return requestUri;
}
//Here I need the loop from 0 to 16 every page and change the pin icons like above if statement
string GenerateRequestUri(string endpoint)
{
string requestUri = endpoint;
requestUri += $"?id=0";
return requestUri;
}
//This is the value who I need to compare result.WaterData.Ardaforecast but does not allow me to write result.WaterData.Ardaforecast and does not allow me to foreach here .. I don't know why ?
var reusult = _restServiceData.GetWaterDataForecast(GenerateRequestUriStations(Constants.EndPoint), GenerateRequestUri(Constants.EndPoint));
}
annotationView.CanShowCallout = true;
configureDetailView(annotationView);
return annotationView;
}
In the comments above the code I mean that when I write:
var reusult = _restServiceData.GetWaterDataForecast(GenerateRequestUriStations(Constants.EndPoint), GenerateRequestUri(Constants.EndPoint));
foreach (var item in IAsyncResult)
{
}
When I try to write result. automatic puts me IAsyncResult.. I don't know why.. ?
Can I get an example of how to loop all the pages and change colors on the markers ?
My GetDataFromAPI look like this:
public IEnumerable<AlertLevel> GetDataFromAPI(int mapCode)
{
var listAlert = new List<AlertLevel>();
var reusult = _restServiceData.GetWaterDataForecast(GenerateRequestUriStations(Constants.EndPoint), GenerateRequestUri(Constants.EndPoint, mapCode));
foreach (var item in reusult.WaterData.Ardaforecast[0].Items)
{

{
dateForecast = item.DateTimeForecast,
levelForecast = item.AlertLevelForecast
};
listAlert.Add(currentData);
}
return listAlert;

EDIT: I have the Quote working on EDIT, but it's not working on Create. I've adjusted my method from my original post. So my issue is I cannot figure out to pass the ID of a newly created record to the quote method.
Student here!
Creating an MVC app and I cannot figure out I'm missing. I thought I had it working and then I moved on, but when I went back to test, I realized it wasn't working and am getting a bunch of errors. I know the reason is because the values I think I'm passing aren't actually being passed.
I have the two scenarios, Create and Edit and when the DB entry is created it should redirect to my quote method, but that is where I'm getting errors. I can't figure out how to pass the values that were just created to the quote method. Any suggestions as to what I'm missing would be appreciated!

}
catch (Exception ex)

Any kind of help would be greatly appreciated. Thanks.
Before you insert, you can check in the DB, if the JourneyID is exists.
if (objDB.FMS_Group6_Module3_BonusMilesRequestt.Any(x => x.JourneyID == objProd.JourneyID))
{
// Exists
}
LINQ query to make sure all values (ex enumerable) are not duplicated
var noDuplicationVariable = enumerableValues.GroupBy(a => a.Key).All(b => b.Count() == 1);
use it as an assertion condition before your function

What I am trying to do is create an audit trail which records the object I am working on (in this case an asset) and I am serializing the class and inserting it into the database for use in reporting, etc.
My question is; is this the way to do it. Is there a better way?
