HttpException - Chrome中超出了最大请求长度

我正在使用ASP.NET MVC 3中的上传器。我正在使用AJAX上传控件(http://valums.com/ajax-upload/)。当我尝试通过IE上传大文件时,一切正常。但是,当我尝试通过Chrome上传大文件时,我在服务器上收到“超出最大长度”的异常。我添加了以下配置设置,认为它可以解决它:

<httpRuntime maxRequestLength="2147483647" executionTimeout="3600" />

虽然没有解决它。我的操作代码如下所示:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult UploadFiles(IEnumerable<HttpPostedFileBase> files)
{
  string home = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "files");
  if (String.IsNullOrEmpty(Request["qqFile"]))
  {
    string filename = string.Empty;
    foreach (string file in Request.Files)
    {
      HttpPostedFileBase postedFile = (HttpPostedFileBase)(Request.Files[file]);
      if (postedFile.ContentLength == 0)
        continue;

      filename = Path.Combine(home, Path.GetFileName(postedFile.FileName));
      if (Directory.Exists(baseDirectory) == false)
        Directory.CreateDirectory(baseDirectory);
      postedFile.SaveAs(filename);
    }
  }
  else
  {
    // MY PROBLEM IS IN HERE
    string filename = Path.Combine(baseDirectory, Request["qqFile"]);

    byte[] buffer = new byte[Request.InputStream.Length];
    Request.InputStream.Read(buffer, 0, buffer.Length);
    System.IO.File.WriteAllBytes(filename, buffer);
  }

  return Json(new { success = true }, "text/html");
}

为什么我无法通过Chrome上传大文件?

您可以尝试设置maxAllowedContentLength

<system.webServer>
    <security>
        <requestFiltering>
             <requestLimits maxAllowedContentLength="X" />
        </requestFiltering>
    </security>
</system.webServer>
