Use Dynamic field in Linq WHERE clause

Sometimes you need to do something like :

SELECT * FROM table WHERE sFieldName = sValue

Here is how to translate the above to LINQ

Dim db As New northwindDataContext    
Dim sFieldName  = "City"
Dim sFieldValue = "Berlin" 

Dim q = From t In db.Customers.AsEnumerable.
        Where(Function(f) f.GetType.GetProperty(sFieldName).GetValue(f,Nothing)  = sFieldValue)
        Select t
