I have a array with type of string and I'm trying to convert it to a new integer array by the code below

  intlist = list1.ConvertAll(New Converter(Of String, Integer)(AddressOf Integer.Parse))

But I always get this error, Visual Studio 2013 doesn't recognize the "ConvertAll".

 Error  1   Argument not specified for parameter 'converter' of 'Public Shared Function ConvertAll(Of TInput, TOutput)(array() As TInput, converter As System.Converter(Of TInput, TOutput)) As TOutput()'. C:\Users\Louis\Documents\Visual Studio 2013\Projects\DataGridCopyPaste\DataGridCopyPaste\Form1.vb   17  19  DataGridCopyPaste

  • I have tested this code and it works (even in VS 2010): Dim list1 As New List(Of String) From {"1", "2", "3"} Dim intlist As List(Of Int32) = list1.ConvertAll(New Converter(Of String, Integer)(AddressOf Integer.Parse)). I also don't understand "Visual Studio 2013 doesn't recognize the 'ConvertAll'" in combination with your error: "Argument not specified". It seems that it actually recognizes the method but doesn't like a parameter. Commented Jul 21, 2014 at 15:10
