Not Returning properly

I was trying to get employee list which not already available in another list. but im getting only first element from array list.
ex : if i try EmployeeId = new int[2] {5, 2}; the list excluding only '5'. So please help me correct my below code.
public JsonResult GetEmployees(int[] EmployeeId)
{
var dbs = new dbContext();
if (EmployeeId != null)
{
foreach (var emp in EmployeeId)
{
var EmpList = dbs.Employees.Select(e => new
{
EmployeeId = e.EmployeeId,
Name = e.EmployeeName,
Job = e.Job.JobName,
Currency = e.Currency.CurrencyName,
Amount = e.Amount
}).Where(o => o.EmployeeId != emp);
return Json(EmpList, JsonRequestBehavior.AllowGet);
}
}
return null
}

Try this :
var employeeList = dbs.Employees.
.Where(e => EmployeeId.All(x=> x != e.EmployeeId))
.Select(e => new
{
EmployeeId = e.EmployeeId,
Name = e.EmployeeName,
Job = e.Job.JobName,
Currency = e.Currency.CurrencyName,
Amount = e.Amount
});
return Json(EmpList, JsonRequestBehavior.AllowGet);
}

Have you tried stepping through your code?
Your foreach iterates over your EmployeeId array.
Since you have a return statement in your foreach it exits the function at that point and it only uses the first element of your array.
You need something like this:
public JsonResult GetEmployees(int[] EmployeeId)
{
var dbs = new dbContext();
if (EmployeeId != null)
{
var EmpList = dbs.Employees.Where(EmployeeId.Contains(e.EmployeeId))
.Select(e => new
{
EmployeeId = e.EmployeeId,
Name = e.EmployeeName,
Job = e.Job.JobName,
Currency = e.Currency.CurrencyName,
Amount = e.Amount
}).Where(o => o.EmployeeId != emp);
return Json(EmpList, JsonRequestBehavior.AllowGet);
}
return null;
}

A few things wrong with this line:
UserTrafficReport_Create model =
await Task.WhenAll(
GetNewModel,
InitialCameras,
GetMonitoredWaysListAndPushViewData(mainRoadID, segmentID, cityid));
Task.WhenAll takes a collection of Task instances as an argument.
You're passing 2 delegates and a task. You probably meant to actually call the first two methods, so that they'll return a task?
Task.WhenAll returns a Task. Awaiting that task won't return anything, so you won't be able to assign anything to model.
Task<UserTrafficReport_Create> modelFactoryTask = GetNewModel(...);
await Task.WhenAll(
modelFactoryTask ,
InitialCameras(...),
GetMonitoredWaysListAndPushViewData(mainRoadID, segmentID, cityid));
UserTrafficReport_Create model = modelFactoryTask.Result;

Setting null in list cause null value in other list

I have two lists which i want to get the different items from them
SearchElement[] criteria = new SearchElement[] {
new SearchElement
{
Comparison = "=",
FieldName = "CableProperty.ProjectId",
FieldValue = int.Parse(comboBoxSource.SelectedValue.ToString()),
LogicalOperator = "" }
};
sourceCables = client.GetCables(criteria, null, "Cores,CableProperty,CableProperty.CableApplication").ToList();
criteria = new SearchElement[] {
new SearchElement
{
Comparison = "=",
FieldName = "CableProperty.ProjectId",
FieldValue = int.Parse(comboBoxDestination.SelectedValue.ToString()),
LogicalOperator = "" }
};
destinationCables = client.GetCables(criteria, null, "Cores,CableProperty,CableProperty.CableApplication").ToList();
diffCables = sourceCables.Except(destinationCables, new CableComparer())
.ToList();
Now I have the different items in diffcable. Sometimes i want to set
diffCable.CableProperty.CableApplication = null;
but when i do that, all the navigation Porperty(CableApplication) in sourcelist is also set to null.
this is the code
if (destinationCableApplications.Contains(diffCable.CableProperty.CableApplication, new CableApplicationComparer()))
{
criteria = new SearchElement[] { new SearchElement { Comparison = "=", FieldName = "ProjectId", FieldValue = int.Parse(comboBoxDestination.SelectedValue.ToString()), LogicalOperator = "" }};
cableApplication = client.GetCableApplications(criteria, null, "").SingleOrDefault();
diffCable.CableProperty.CableApplication = null;
}
excatly in after this line
diffCable.CableProperty.CableApplication = null;
all the
sourcecables[0].CableProperty.CableApplication
sourcecables[1].CableProperty.CableApplication
.....
sourcecables[100].CableProperty.CableApplication
are set to null
what should i do to not lose the navigation property in sourcelist when i set null to navigation property in diffcable ?

easiest way is using MemoryStream..
Here is a sample,
[Serializable]
public class temp
{
public int a;
}
class Program
{
public static T DeepClone<T>(T a)
{
using (MemoryStream stream = new MemoryStream())
{
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, a);
stream.Position = 0;
return (T)formatter.Deserialize(stream);
}
}
static void Main(string[] args)
{
List<temp> list1 = new List<temp>();
list1.Add(new temp { a = 1 });
list1.Add(new temp { a = 2 });
list1.Add(new temp { a = 3 });
List<temp> list2 = DeepClone<List<temp>>(list1);
list1[1].a = 4;
Console.WriteLine(list2[1].a);
Console.ReadKey();
}
}
Note: class must be Serializable.
This will work for all value and reference types.

You are doing a copy by reference without realising it. Look into Cloning your objects or creating new lists.
List<int> newCopyList = new List<int>(originalList);

Open XML data lables

I am creating a bar chart with openxml and need to have the x axis labels on the bottom of the chart rotated at a 45 degree angle.

Find the items matching any condition from the generic list

I have collection of patient in a lists named lst_Patient.
And this is method where i get the info from user:
public Patient[] GetPatientsBySearchParams(DataPair[] dataPair)
{
//return the array patients that match any of the criteria
//Right Now I ma doing this didn't get any success :
List<Patient> P = new List<Patient>();
P = lst_Patient.FindAll(p => { p.FirstName = dataPair[0].OutputValue.ToString();
p.LastName = dataPair[1].OutputValue.ToString();
return true;
return P.ToArray();
}
On a button click i take the info entered in the textbox by the user:
private DataPair[] dpair;
private void Button_Click(object sender, RoutedEventArgs e)
{
InvalidSearch.Visibility = Visibility.Collapsed;
SearchResults.Visibility = Visibility.Visible;
dpair = new DataPair[]{
new DataPair { Name = "FirstName", OutputValue = fst_Name.Text },
new DataPair { Name = "LastName", OutputValue = lst_Name.Text },
new DataPair { Name = "DateOfBirth", OutputValue = dob.Text },
new DataPair { Name = "SSN", OutputValue = ssn.Text },
new DataPair { Name = "PracticeNumber", OutputValue = pract_nbr.Text },
new DataPair { Name = "ReferenceNumber", OutputValue = ref_nbr.Text },
new DataPair { Name = "PlaceOfService", OutputValue = pos.Text },
new DataPair { Name = "DateOfService", OutputValue = dos.Text},
new DataPair { Name = "RenderingProvider", OutputValue = rndrng_prov.Text },
new DataPair { Name = "AdmissionDate", OutputValue = admsn_date.Text }
};
this.FetchData();
}
private void FetchData()
{
Patient[] p = client.GetPatientsBySearchParams(dpair);
}

public Patient[] GetPatientsBySearchParams(DataPair[] dataPair)
{
P = lst_Patient.FindAll(
delegate(Patient tmp){
if(tmp.FirstName = dataPair[0].OutputValue || tmp.LastName = dataPair[1].OutputValue)
return true;
else
return false;
}
);
return P.ToArray();
}

You should use reflection to call the property whose name gets passed.
p.GetType().GetProperty(dataPair[i].Name).GetValue(p) == dataPair[i].OutputValue;
