ActionResult의 Type중 ContentResult를 이용한다.
먼저, Response 에 Buffer 설정과 Header 설정을 한다.
Response.ClearContent();
Response.AppendHeader("content-disposition", attachment);
Response.Buffer = true;
다음 ContentResult의 결과를 넣어준다.
<table>로 표현하는 경우에는 Excel에서 표로 읽는 것이 가능하다.
StringBuilder sb = new StringBuilder();
sb.Append("<table>");
sb.Append("<tr>");
sb.Append("<td>Date</td>");
sb.Append("<td>Comment</td>");
sb.Append("</tr>");
foreach(JoinOrLeaveReason joinOrLeaveReason in joinOrLeaveReasons)
{
sb.Append("<tr>");
sb.AppendFormat("<td>{0:yyyy-MM-dd HH:mm:ss}</td>", joinOrLeaveReason.CreateDate);
sb.AppendFormat("<td>{0}</td>", joinOrLeaveReason.Comment);
sb.Append("</tr>");
}
sb.Append("</table>");
ContentResult contentResult = new ContentResult();
contentResult.ContentType = "application/wnd.ms-excel";
contentResult.Content = sb.ToString();
contentResult.ContentEncoding = Encoding.UTF8;
return contentResult;
사용될 수 있는 Content-Type의 종류는 다음과 같다.
1) Multipart Related MIME 타입
- Content-Type : Multipart/related(기본형태)
- Content-Type : Application/X-FixedRecord
- Content-Type: Text/x-Okie; charset=iso-8859-1;
2) XML Media의 타입
- Content-Type : text/xml
- Content-Type : Application/xml
- Content-Type : Application/xml-external-parsed-entity
- Content-Type : Application/xml-dtd
- Content-Type : Application/mathtml+xml

3) Application의 타입
- Content-Type : Application/EDI-X12: Defined in RFC 1767
- Content-Type : Application/EDIFACT: Defined in RFC 1767

* x-www-form-urlencode와 multipart/form-data은 둘다 폼 형태이지만 x-www-form-urlencode은 대용량 바이너리 테이터를 전송하기에 비능률적이기 때문에 대부분 첨부파일은 multipart/form-data를 사용하게 된다.
4) 오디오 타입
- Content-Type : Type audio: Audio
- Content-Type : audio/mpeg: MP3 or other MPEG audio
- Content-Type : audio/x-ms-wma: Windows Media Audio;
- Content-Type : audio/vnd.rn-realaudio: RealAudio; 등등
5) Multipart 타입(아카이브 또는 개체)
- Content-Type : multipart/mixed: MIME E-mail;
- Content-Type : multipart/alternative: MIME E-mail;
- Content-Type : multipart/related: MIME E-mail; Defined in RFC 2387 and used by MHTML(HTML mail)
- Content-Type : multipart/formed-data : <-- 파일 첨부
6) TEXT 타입
- Content-Type : text/css:
- Content-Type : text/html:
- Content-Type : text/javascript
- Content-Type : text/plain:
- Content-Type : text/xml:
