Evalute part of LINQ expression before translating to SQL statements

Question

Dim instanceOfMyClass As New MyClass()
'... Some code to manipulate instanceOfMyClass.MyArrayField
Dim thisYear = DateTime.Today.Year
Dim records = (
  From i In dbContext.MyTable
  Where i.MyCol >= thisYear - instanceOfMyClass.MyArrayField.Length AndAlso i.MyCol <= thisYear - 1
).ToArray()

Class MyClass
  Friend MyArrayField As String()
End Class

Running above code throws an exception because EF6 doesn't know how to translate instanceOfMyClass.MyArrayField.Length to SQL expression. Of course I can do:

Dim anIntermediateVar = instanceOfMyClass.MyArrayField.Length
Dim records = (
  From i In dbContext.MyTable
  Where i.MyCol >= thisYear - anIntermediateVar AndAlso i.MyCol <= thisYear - 1
).ToArray()

It just feels a bit unintuitive to me. I wonder if there's a syntax/function/whatever to mark a section of expression so that .NET runtime will evaluate the code within before translating? Something like:

From i In dbContext.MyTable
Where i.MyCol >= thisYear - EvalThisFirst(instanceOfMyClass.MyArrayField.Length) AndAlso i.MyCol <= thisYear - 1

so that when EF6 doing LINQ-to-TSQL translation it's translating from:

From i In dbContext.MyTable
Where i.MyCol >= thisYear - 5 AndAlso i.MyCol <= thisYear - 1

Does such mechanism exist?
