//C#
public string MakeSpace(string text)
{
    StringBuilder sentenceBuilder = new StringBuilder();
    string[] strings = text.Split((char)32);

    foreach (string s in strings)
    {
        if (string.IsNullOrEmpty(s))
            continue;

        StringBuilder spaceBuilder = new StringBuilder();
        for (int i = 0; i < s.Length; i++)
        {
            spaceBuilder.Append(" ");
        }

        sentenceBuilder.Append(string.Format("{0}{1}", spaceBuilder.ToString(), s));
    }

    return sentenceBuilder.ToString();
}

'VB.Net
Public Function MakeSpace(text As String) As String
    Dim sentenceBuilder As New StringBuilder()
    Dim strings As String() = text.Split(CChar(32))

    For Each s As String In strings
        If String.IsNullOrEmpty(s) Then
            Continue For
        End If

        Dim spaceBuilder As New StringBuilder()
