Special special = (from s in weblog.Special
where s.SpecalID == id
select s).FirstOrDefault();
HttpRequest request = System.Web.HttpContext.Current.Request;
if (request.Files.Count > 0)
{
string path = HttpContext.Request.MapPath(UserSpecialRootVirtual(special.User, special.SpecalID));
string fileName = System.IO.Path.GetFileName(request.Files[0].FileName);
request.Files[0].SaveAs(path + fileName);
TempData["message"] = "上传成功";
return RedirectToAction("Details/" + special.SpecalID);

[解决办法]
有可能


<configuration>
<system.web>
<httpRuntime maxRequestLength="32768" />
</system.web>
</configuration>

maxRequestLength: Optional Int32 attribute.
Specifies the limit for the input stream buffering threshold, in KB. This limit can be used to prevent denial of service attacks that are caused, for example, by users posting large files to the server.
The default is 4096 (4 MB).
