LINQ query requesting that the object type declared rather than bing implicit

oEngine = New FileHelperEngine(GetType(CUPSMapping))
 Dim oMappings As CUPSMapping() = CType(oEngine.ReadFile(Filename), CUPSMapping())

Dim query = From oMap In oMappings
                        Select oMap


The error message when mouse over 'query' is this.  Linq has been imported

Variable declaration without an 'AS' clause; type of object assumed

Either put "Option Infer On" at the top of the code file, or change it at the project level in the project properties compile tab.

Dim query = From oMap In oMappings
                        Select oMap

should be:

dim query as List(of CupsMapping) = From  oMap In oMappings
                        Select oMap

'It's complaining that query type is not defined.  You need to specify query as something.



Is query correct or is it truly the result?

I think instead that the problem is on the range variable:

Dim query = From oMap As CUPSMapping In oMappings
                        Select oMap

Open in new window


If it were as ged325 describes, then what would you do when you were SELECTing an anonymous type!!!

On a side note, what is the purpose of the LINQ query anyway? You are merely selecting with nothing else. The net effect is you get back an IEnumerable(Of CUPSMapping). An array should already be enumerable. Are you passing the result of this query to some other function which has an explicit IEnumerable(Of CUPSMapping) signature?
