How to Split a String using LINQ and Handle Empty Strings

While splitting strings using a delimiter, it's important to consider empty strings. A user recently mailed me with this requirement and he wanted to do it using LINQ. Here's a code sample I borrowed from cccook which shows how to do so:


    protected void Page_Load(object sender, EventArgs e)


        string str = "Are;You;A;Regular;Visitor;;;?";

        Regex.Split(str, ";", RegexOptions.ExplicitCapture)

            .Where(s => !String.IsNullOrEmpty(s))


            .ForEach(s => Response.Write(s+"\n"));




Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

    Dim str As String = "Are;You;A;Regular;Visitor;;;?"

    Regex.Split(str, ";", RegexOptions.ExplicitCapture).Where(Function(s) (Not String.IsNullOrEmpty(s))).ToList().ForEach(Function(s) Response.Write(s + Constants.vbLf))

End Sub
