public ActionResult ExportToOutlook(Guid id)
{
var query = new GetActivityByIdQuery();
var queryResult = query.Execute(id);
var outlookCalendarFileCreator = new OutlookCalendarFileCreator();
var contentData = outlookCalendarFileCreator.CreateOutlookCalendarFile(queryResult);
var fileName = String.Format("Activity.ics", queryResult.ActivityType.Name, queryResult.Date) ;
return File( contentData,"text/plain", queryResult.Notes + fileName);
}
public class OutlookCalendarFileCreator
{
public Byte[] CreateOutlookCalendarFile(ActivityDetailsResponseDto responseDto)
{
byte[] contentData;
HttpRequest request = System.Web.HttpContext.Current.Request;
string baseUrl = request.Url.GetLeftPart(UriPartial.Authority);
var hLink = string.Format("{0}/Activities/Details?id={1}", baseUrl, responseDto.Id);
var sb = new StringBuilder();
sb.Append(@"X-ALT-DESC;FMTTYPE=text/html:<!DOCTYPE HTML PUBLIC ""-//W3C//DTD HTML 3.2//EN"">\n<HTML><BODY>");
sb.Append(string.Format("<a href='{0}'>{1}</a>", hLink, responseDto.Notes));
sb.Append("</BODY></HTML>");
using (var memoryStream = new MemoryStream())
{
using (var writer = new StreamWriter(memoryStream))
{
writer.AutoFlush = true;
//HEADER
writer.WriteLine("BEGIN:VCALENDAR");
writer.WriteLine("VERSION:1.0");
writer.WriteLine("BEGIN:VEVENT");
//BODY
writer.WriteLine("DTSTART:" + responseDto.Date.ToUniversalTime().ToString("o"));
writer.WriteLine("DTEND:" + responseDto.Date.AddHours(1).ToUniversalTime().ToString("o"));
writer.WriteLine("SUMMARY:" + responseDto.ActivityType.Name);
writer.WriteLine("DESCRIPTION:" + sb.ToString());
//FOOTER
writer.WriteLine("END:VEVENT");
writer.WriteLine("END:VCALENDAR");
writer.Flush();
contentData = new byte[(int)memoryStream.Length];
memoryStream.Position = 0;
memoryStream.Read(contentData, 0, (int)memoryStream.Length);
return contentData;
}
}
}
推荐答案
同样，在DESCRIPTION后面有:".您需要输入;" -分号与冒号.
Again, you have ":" after DESCRIPTION. You need to have ";" - semicolon vs. colon.
sb.Append(@"<!DOCTYPE HTML PUBLIC ""-//W3C//DTD HTML 3.2//EN"">\n<HTML><BODY>");
sb.Append(string.Format("<a href='{0}'>{1}</a>", hLink, responseDto.Notes));
sb.Append("</BODY></HTML>");
...
writer.WriteLine("DESCRIPTION;X-ALT-DESC;FMTTYPE=text/html:" + sb.ToString());
