Question

 reader = server.ExecuteReader(CommandType.Text, getPermissionlistQuery, param);
        var results = new List<string>();
        while (reader.Read())
        {
            results.Add(reader["permissionName"].ToString());
        }
        reader.Close();
        Session.Add("Permissions", results);

I am adding results to the session, how can I retrieve it in another page.

results is a list of values

var permissionList = Session["Permissions"];         
        string check = "Create Groups";
        if (permissionList.Any(item => item.Equals(check)))
        {
            // results contains the value in check 
        }

and I want to check whether the permission is available in the Permission list but the if statement is throwing a error

'object' does not contain a definition for 'Any' and no extension method 'Any' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)

UPDATED: Change bottom code to this:

IList<String> collection = (IList<String>) Session["Permissions"];

string check = "Create Groups";

if (collection.Any(item => item.Equals(check)))
{
   // results contains the value in check 
}

Also, reference:
