It would be quite useful if we can use “Session” inside App_Code in ASP.Net. E.G. You may not need to pass the “Session” variable into the Method, You only need to call the Session(“Variable Name”) inside the method.
However when I try to type the following Code in the vb/cs page which is under App_Code folder. It shows the error like this.
VB.Net
Dim Var as String = Session(“VariableName”)
C#
string var = (string) Session[“VariableName”];
Error: The type or namespace name ‘HttpSessionState’ could not be found
Here it is the solutions:
To use Session variable inside App_Code Folder.
You need to import a references: Please see the sample code below.
VB.Net
Import System.Web.SessionState
C#
using System.Web.SessionState;
VB.Net
Dim ses As HttpSessionState = HttpContext.Current.Session
Dim VarSession As String = “”
If ses(“VariableName”) IsNot Nothing Then
VarSession = DirectCast(ses(“VariableName”), String)
End If
C#
HttpSessionState ses = HttpContext.Current.Session;
string VarSession = “”;
if (ses[“VariableName”] != null)
{
VarSession = (string)ses[“VariableName”];
}
Hope you find it useful.
Happy Coding =).
