How can i resolve implicitly typed variable error?

I have the following:

   var dbColumns =  null; 

  dbColumns = dbColumnsCollection.Where(s => s.Field1 == "test");

but get an error "cannot assign to an implicitly typed variable"

How can I initialize the variable dbColumns ?

thanks

This is because C# is strongly type. And var is used for anonymous programming. Thus declaring a null for a var cannot and will not work.

So Code like this just won't work out because the compiler can't detect the datatype of dbColumns.

var dbColumns =  null;

Two ways to declare dbColumns,

First if you want to retain the variable then use

var dbColumns =  (IEnumerable<PocoClass>)null;

or the reliable good ol way

 IEnumerable<PocoClass> dbColumns =  null

EDIT: You may also still use IQueryable if you are still building the LINQ query.
