ASP.NET:如何从处理程序访问会话?

问题描述：

我正在尝试在中存储一些值来自 Handler 页面的会话，在我重定向到 WebForms 页面之前，它将获取 Session 值并预填充网页表格:

i'm trying to store some values in the Session from a Handler page, before i do a redirect to a WebForms page, that will pick up the Session values and pre-fill the WebForm:

public class Handler : IHttpHandler
{
   public void ProcessRequest(HttpContext context)
   {
      ...
      context.Session["StackOverflow"] = "overflowing";
      context.Response.Redirect("~/AnotherPage.aspx");
      ...
   }
   ...
 }

除了 context.Session 对象为空.

如何从处理程序访问会话状态?

How do i access Session state from a handler?

答

实施 System.Web.SessionState.IRequiresSessionState 接口

public class Handler : IHttpHandler, System.Web.SessionState.IRequiresSessionState 
{   
  public void ProcessRequest(HttpContext context)  
  {      
    context.Session["StackOverflow"] = "overflowing";      
    context.Response.Redirect("~/AnotherPage.aspx");      
  }

}
