When utilizing the code below, I can determine the location of logged-in users. However, there are some users who do not have a specific location assigned. For example, Administrators are common for all locations. In such cases, how can I set it so that if the value is null, it will display the location as ALL?
@HttpContext.Current.Session["UserLocation"].ToString()
Why not consider utilizing a different method instead of relying on session state for storing user data?
@(HttpContext.Current.Session["UserLocation"] != null
? HttpContext.Current.Session["UserLocation"].ToString()
: "ALL")
While the code snippet above may work, it's important to note that maintaining user information in session state is not recommended as it can lead to scalability issues.
For a more concise answer inspired by @Leo, consider trying the following:
@((string)HttpContext.Current.Session["UserLocation"] ?? "ALL")
Handling session state is not my forte, but could this be a potential solution?
if(string.IsNullOrEmpty(@HttpContext.Current.Session["UserLocation"]) && userIsAdministrator)
{
@HttpContext.Current.Session["UserLocation"] = "ALL";
}
To efficiently achieve this, consider using the null-coalescing operator :
string userLocation = @((string)HttpContext.Current.Session["UserLocation"] ?? "ALL");
The concept is straightforward; if the left side is null, it will return the value specified on the right side. If the left side is not null, it will return the left side.
Don't forget to cast to string since Session returns the base type object.
