I have a method in my app that populates DataTable with the data using the following code:

DataTable dt = this.attachmentsDataSet.Tables["Attachments"];

foreach (Outlook.Attachment attachment in this.mailItem.Attachments)
{
    DataRow dr = dt.NewRow();
    dr["Index"] = attachment.Index;
    dr["DisplayName"] = String.Format(
        CultureInfo.InvariantCulture,
        "{0} ({1})", 
        attachment.FileName,
        FormatSize(attachment.Size));
    dr["Name"] = attachment.FileName;
    dr["Size"] = attachment.Size;

    dt.Rows.Add(dr);
}

I was wondering if I could achieve the same functionality using LINQ in order to shorten this code a bit. Any ideas?
