        string oldFile = Server.MapPath("~/Files/" + fileName);
        string newFile = Server.MapPath("~/Files/" + fileName.Replace(",", ""));
        if (System.IO.File.Exists(oldFile))
        {
            System.IO.File.Copy(oldFile, newFile, true);
            System.IO.File.Delete(oldFile);
        }
    }
    // Using FileInfo MoveTo Method.
    foreach (var fileName in filesName)
    {
        string oldFile = Server.MapPath("~/Files/" + fileName);
        string newFile = Server.MapPath("~/Files/" + fileName.Replace(",", ""));
        System.IO.FileInfo fi = new System.IO.FileInfo(oldFile);
        if (fi.Exists)
        {
            fi.MoveTo(newFile);
        }

    Dim filesName As String() = {"ABCD,Test.pdf", "ABCD,BBCDFPT,Test.Docx"}
    ' Using File Copy Method.
    For Each fileName In filesName
        Dim oldFile As String = Server.MapPath("~/Files/" & fileName)
        Dim newFile As String = Server.MapPath("~/Files/" & fileName.Replace(",", ""))
        If IO.File.Exists(oldFile) Then

        Dim oldFile As String = Server.MapPath("~/Files/" & fileName)
        Dim newFile As String = Server.MapPath("~/Files/" & fileName.Replace(",", ""))
        Dim fi As IO.FileInfo = New IO.FileInfo(oldFile)
