How do I write this lambda select method in VB.net?
.net-3.5, lambda, linq, vb.net
Solution
This would be:
Dim blah = exampleItems.Select (Function(x) New With { .Key = x.Key, .Value = x.Value }).ToList
For details, see Anonymous Types. (Depending on usage, you might also want Key or Value to be flagged with the Key keyword.)
That being said, `Dictionary(Of TKey, Of TValue)` already is an `IEnumerable(Of KeyValuePair(Of TKey, Of TValue)`, so you can also just do:
Dim blah = exampleItems.ToList
And you'll have a list of KeyValuePair, which has a `Key` and `Value` property already. This really means there's no need to make the anonymous type.
Problem
For I've tried this: ``` Dim exampleItems As Dictionary(Of String, String) = New Dictionary(Of String, String) Dim blah = exampleItems.Select (Function(x) New (x.Key, x.Value)).ToList 'error here ``` But I'm getting a syntax error and all the examples that I've seen are in C#.
