asp.net-mvc-3 – 带有重音IE8的ASP MVC3 FileResult – 被窃听

但在IE8文件类型中是“未知文件类型”,并显示“文件”作为文件名(实际上是URL的最后一部分).

有没有人知道解决方法？替换文件名中的“特殊”字符除外？

测试代码:(文件|新项目|添加控制器)

public class FileController : Controller
{
    public ActionResult Index(bool? Accents)
    {
        byte[] content = new byte[] { 1,2,3,4 };

        return File(content,"application/octet-stream",true.Equals(Accents) ? "dsaé.txt" : "dsae.txt");
    }
}

像这样测试：
http://localhost/file,和
http://localhost/file?accents=true

编辑=>对我来说,“解决方案”,如果有兴趣的话：

public class FileContentResultStupidIE : FileContentResult //yeah,maybe i am not totally "politically correct",but still...
{
    public FileContentResultStupidIE(byte[] fileContents,string contentType) : base(fileContents,contentType) { }

    public override void ExecuteResult(ControllerContext context)
    {
        var b = context.HttpContext.Request.Browser;
        if (b != null && b.Browser.Equals("ie",StringComparison.OrdinalIgnoreCase) && b.MajorVersion <= 8)
        {
            context.HttpContext.Response.AppendHeader("Content-Disposition","attachment; filename="" + HttpUtility.UrlPathEncode(base.FileDownloadName) + """);
            WriteFile(context.HttpContext.Response);
        }
        else
        {
            base.ExecuteResult(context);
        }
    }
}
