My initial thoughts were that the HTTPContext object would
not be in scope in a middle tier object method, hence
passing individual session values as method parameters. Is
this correct?
Here is a subset of the sample I knocked up to test this
scenario:
public string GetTypes()
{
using System.Web;
StringBuilder sb = new StringBuilder();
sb.Append(HttpContext.Session["UserID"].ToString());
return(sb.ToString());
}
The following message is generated:
An object reference is required for the nonstatic field,
method, or property 'System.Web.HttpContext.Session'.
Do I need to pass the HTTPContext object to the middle
tier object through a method parameter?
