Webservice and session

[Morten V. Pedersen]

Hello

I have a web-service with a web-method where sessionstate=false.
The web method calls a method in another assembly.

Also I have a web-method where sessionstate=true which calls the same method
in the other assembly.

Here I can always access HttpContext.Current, but how do I determine if I
can access HttpContext.Current.Session?

It's in 1.1 framework.

Hi Morten,

Thank you for posting.

As for the SessionState setting for ASP.NET webservice, it is a webmethod
level setting (through the WebMethodAttribute), so there is not directly
property for us to check this in the webservice class. However, if you do
want to check certain WebMethod's SessionState setting, you can consider
using the Reflection api to query the "WebMethodAttribute" attribute. For
example:

===============
MethodInfo mi = this.GetType().GetMethod("HelloWorld",
System.Reflection.BindingFlags.Instance |
System.Reflection.BindingFlags.Public);


object[] objs = mi.GetCustomAttributes(typeof(WebMethodAttribute),
true);


if (objs != null && objs.Length >0)
{
WebMethodAttribute wsa = (WebMethodAttribute)objs[0];

if (wsa != null)
{
return "Session: " + wsa.EnableSession;
}
}
============================

BTW, generally, it is not recommended that we use SessionState or other
stateful storage in Webservice since they're platform dependent.

Hope this helps.
