[C#] 使用 iCal.NET 產生 .ICS 行事曆事件+附加檔案
2023-02-07
今天接續之前透過 iCal.NET 來建立 .ics 的行事曆預約檔案的延伸
我們天才的業主希望在事件裡面加入 COUPON 圖片，我原本以為不行的想說婉拒
但是我後來查了一下好像可以，測試一下竟然成功，那就筆記一下
如果不知道 iCal.NET 的可以參考我上篇文章 使用 iCal.NET 產生 .ICS 行事曆事件+鬧鐘 ，這一篇是延續
主要就是建立事件後加上一張圖片，其實說穿了就是轉 base64
但是必須要加入 X-FILENAME 這去宣告檔名

| evt.Attachments.Add(binaryAttachment); | |
| var calendar = new Ical.Net.Calendar(); | |
| calendar.Properties.Add(new Ical.Net.CalendarProperty("X-WR-CALNAME", title)); | |
| calendar.AddTimeZone("Asia/Taipei"); | |
| calendar.Events.Add(evt); | |
| var serializer = new Ical.Net.Serialization.CalendarSerializer(); | |
| var serializedCalendar = serializer.SerializeToString(calendar); | |
