How to Convert a character array to string array

Question

I have the code below that requires me to convert a character array to string array, but I get the following error: Option Strict On disallows implicit conversions from '1-dimensional array of Char' to 'System.Collections.Generic.IEnumerable(Of String)'

    Dim lst As New List(Of String)
    lst.AddRange(IO.Path.GetInvalidPathChars())
    lst.AddRange(IO.Path.GetInvalidFileNameChars())

    lst.Add("&")
    lst.Add("-")
    lst.Add(" ")

    Dim sbNewName As New StringBuilder(orignalName)
    For i As Integer = 0 To lst.Count - 1
        sbNewName.Replace(lst(i), "_")
    Next

    Return sbNewName.ToString

I tried using a converter through Array.ConvertAll, but couldn't find a good example, I could use a loop, but thought there would be a better way. Could anyone help?

Just change the lst.AddRange lines to this:

Array.ForEach(Path.GetInvalidPathChars(), AddressOf lst.Add)
Array.ForEach(Path.GetInvalidFileNameChars(), AddressOf lst.Add)

VB Linq syntax is not a strong point for me, but to get you started, consider selecting the items from the character arrays and converting each to string. In C#, that would be

lst.AddRange(System.IO.Path.GetInvalidPathChars().Select(c => c.ToString());

Thanks to NYSystemsAnalyst for the VB syntax

lst.AddRange(System.IO.Path.GetInvalidPathChars().Select(Function(c) c.ToString()))

Without Linq, you could simply iterate in a loop explicitly

For Each c as Char in System.IO.Path.GetInvalidPathChars()
    lst.Add(c.ToString())
Next c

This is also an option. Here is the VB syntax: lst.AddRange(Path.GetInvalidPathChars().Select(Function(c) c.ToString())) lst.AddRange(Path.GetInvalidFileNameChars().Select(Function(c) c.ToString()))
