converting VB function with linq query to C# function
I have a ASP.NET MVC application. I'm using Visual Studio 2013.
I'm using VB.
For my data model I created a model called Northwind.dbml
In that model I'm using the Employees table from the Northwind database.
So in my controller I have a function that looks like this:
This function works just fine.
So now I'm creating the C# version of the same application.
I'm having trouble converting this VB function shown above to C#.
This is what i have so far:
If you look at the picture, the parts towards the end of my function have a little red mark, I'm getting those as wrong.
Anyone know where I'm making a mistake in translating the VB function above to C#?

' To Get JSON Data
Public Function SelectNorthwindData(ByVal sidx As String, ByVal sord As String, ByVal page As Integer, ByVal rows As Integer) As ActionResult
Dim context As New NorthwindDataContext
Dim pageIndex As Integer = Convert.ToInt32(page) - 1
Dim pageSize As Integer = rows
Dim totalRecords As Integer = context.Employees.Count()
Dim totalPages As Integer = CInt(Math.Ceiling(CSng(totalRecords) / CSng(pageSize)))
Dim jsonData = New With { _
.total = totalPages, _
.page = page, _
.records = totalRecords, _
.rows = (From p In context.Employees _
Order By (p.LastName & " " & sord) _
Select New With {.id = p.EmployeeID, .cell = {p.EmployeeID, p.LastName, p.FirstName, p.Title}}).ToArray()}
Return Json(jsonData, JsonRequestBehavior.AllowGet)
