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)
