I would like to write my result set to a text file without using a For Each Loop. Is there a quicker more efficient way to stream Linq to Entities or Linq to Objects?

Could you elaborate on the way the object is to be stored into the text file? And your source collection.

I am going to assume you need to store an IEnumerable(Of String) into a file separated by comma. This can be done fairly directly using the Aggregate extension.

VB

' We need to write the IEnumerable(Of String) SourceCollection into the text file "Numbers.txt"
        My.Computer.FileSystem.WriteAllText("numbers.txt", SourceCollection.Aggregate(Function(item, aggregator) String.Format("{1},{0}", aggregator, item)), False)
