asp.net web api 下载文件在IE浏览器文件名显示乱码

[小驴来这里学习]

代码是这样的：

            ContentDispositionHeaderValue disposition = new ContentDispositionHeaderValue("inline");

            disposition.FileName = temp.Name + "." + temp.ExtName;
            disposition.Name = temp.Name;
            disposition.Size = (long)temp.Size;

            string miniType = GetMiniType(temp.ExtName);

            HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.OK);
            result.Content = new ByteArrayContent(tempData.Data);
            result.Content.Headers.ContentType = new MediaTypeHeaderValue(miniType);
            result.Content.Headers.ContentDisposition = disposition;

            return result;

下载的时候，
firefox是这样的：

IE8是这样的：

局部变量：


请问是什么原因？要怎么修改？

http响应头里要设置字符集，看看这篇http://wenku.baidu.com/link?url=VNXc5wyiwhZDbggNITksltfQMwo0nou3KVRdI_gUF_zBYCs2DpWvsaD9bTILzQmSW5uf1uwQzy8iE4CpijV1Qb8CzdCHdA9hjQZLSCTiFYC

楼上的我没看，我是这样解决的。 如果不判断IE浏览器，都用utf-8的话，火狐浏览器下载时，中文会乱码

            var useragent = Request.Headers.UserAgent.ToString();
                if (useragent.Contains("MSIE"))
                {
                    disposition.FileName = System.Web.HttpUtility.UrlEncode(temp.Name, System.Text.Encoding.UTF8) + "." + temp.ExtName;
                    disposition.Name = System.Web.HttpUtility.UrlEncode(temp.Name, System.Text.Encoding.UTF8);
                    disposition.Size = (long) temp.Size;
                }
                else
                {
                    disposition.FileName = temp.Name + "." + temp.ExtName;
                    disposition.Name = temp.Name;
                    disposition.Size = (long) temp.Size;
                }

HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.OK); result.Content = new ByteArrayContent(System.Text.Encoding.Default.GetBytes("中国".ToCharArray())); result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/vnd.ms-excel"); result.Content.Headers.ContentDisposition = ContentDispositionHeaderValue.Parse("attachment;filename=" + HttpUtility.UrlEncode("测试.txt")); ---楼主方法网上也看到过
