User Identity in ASP.Net modelling

Question

I have a table with Listings and I want users to be able to mark their favourite listings. To do that I would have a new table with User ID and Listing Id data. Users should be only able to see their favourite listings.

I am using ASP.NET default authentication. The way to get the User Id would be

User.Identity.Name;

??

Is that the userId I should store? Is that the common approach?

Answer 1

The User.Identity.Name will have the value of whatever you sign in the user with. For example with forms authentication:

FormsAuthentication.SetAuthCookie(thisWillBeTheUserIdentityNameValue, false);

With claims authentication it will be the value you set for the claim type ClaimTypes.Name :

var claim = new ClaimsIdentity(new[]
{
    new Claim(ClaimTypes.Name, thisWillBeTheUserIdentityNameValue)
});

If you sign in the user with their user id you could use User.Identity.Name .
