并使用以下行 -

     public void downloadAttachment(Attachment attach)
    { 
        SmartsheetRequest getAttachment = new SmartsheetRequest { callURL = "/attachment/" + attach.Id, method = "GET", contentType = "application/json" };
        var jsonGetAttachment = getAttachment.MakeRequest("null");
        getAttachment.DownloadAttachment(jsonGetAttachment["url"], jsonGetAttachment["sizeInKb"], jsonGetAttachment["name"]);
