How to use? / 使い方

public ActionResult Picture(int id)
{
  var imagePath = HttpContext.Server.MapPath("~/App_Data/user/{id}/picture.png");
  var lastWriteTime = System.IO.File.GetLastWriteTimeUtc(imagePath);

  return new CacheableContentResult(
    contentType: "image/png",
    lastModified: lastWriteTime,

Return the instance of CachebleContentResult class in MVC action method specified with ETag, and/or the date time of last modified, and the function which return the binary content as byte[] to responding you want.

The function which return the content you specified does not call if not needed, then you can implement "lazy loading".

See the example.

MVC アクションメソッド内で、ETag、および/あるいは最終更新日、そして応答に返したいバイナリコンテンツを byte[] で返す関数を指定した CachebleContentResult クラスのインスタンスを返します。

必要となるまでコンテンツを返す関数は呼び出されませんので、遅延読み込みが実装できます。
