c# - FilePathResult 不适用于 swf 文件？

Question

我正在使用 FileResult 在我的网站中显示文件，如下所示：

public ActionResult GetSwf(long id = 0)
{
    if (id <= 0) return null;
    Attachment attachment = Service.GetAttachmentById(id);
    if (attachment == null) return null;

    string filename = attachment.Name;
    string mimeType = "application/x-shockwave-flash";
    string absoluteFilePath = UploadedPaths.GetAbsolutePath(attachment.Path);

    return File(absoluteFilePath, mimeType, filename);
}

它不适用于以下标签，浏览器将下载文件而不是显示它！

<object type="application/x-shockwave-flash" width="220" height="166" data="File/GetSwf/1232" class="flash-object" data-name="ads-file"></object>

出了什么问题，我该如何解决？

Answer 1

最终，我找到了解决方案。
我不得不将操作更改如下：

public ActionResult GetSwf(long id = 0)
{
    if (id <= 0) return null;
    Attachment attachment = Service.GetAttachmentById(id);
    if (attachment == null) return null;

    string filename = attachment.Name;
    string mimeType = "application/x-shockwave-flash";
    string absoluteFilePath = UploadedPaths.GetAbsolutePath(attachment.Path);

    byte[] bytes = System.IO.File.ReadAllBytes(absoluteFilePath);
    return new FileContentResult(bytes, mimeType);
}
