我有一个使用响应BinaryWrite方法渲染流的视图.这一切都在ASP.NET 4使用Beta 2工作正常,但在RC版本中抛出此异常：
“HttpException”,“OutputStream is not
available when a custom TextWriter is
used.”
<%@ Page Title="" Language="C#" Inherits="System.Web.Mvc.ViewPage" %>
<%@ Import Namespace="System.IO" %>
<script runat="server">
protected void Page_Load(object sender,EventArgs e)
{
if (ViewData["Error"] == null)
{
Response.Buffer = true;
Response.Clear();
Response.ContentType = ViewData["DocType"] as string;
Response.AddHeader("content-disposition",ViewData["Disposition"] as string);
Response.CacheControl = "No-cache";
MemoryStream stream = ViewData["DocAsStream"] as MemoryStream;
Response.BinaryWrite(stream.ToArray());
Response.Flush();
Response.Close();
}
}
</script>
</script>
视图是从客户端重定向生成的(jquery替换前一页中的位置调用,使用Url.Action帮助程序渲染链接当然).这一切都在一个iframe中.
任何人都有一个想法为什么会发生这种情况？
