c# - Update user info in View Identity -

i have extension class includes method this:

public static string getname(this iprincipal user)     {         if (user.identity.isauthenticated)         {             claimsidentity claimsidentity = user.identity claimsidentity;             foreach (var claim in claimsidentity.claims)             {                 if (claim.type == "name")                 {                     return claim.value;                 }             }             return "";         }         else             return "";     } 

after call action update user table include name, name called @user.getname() not update although column in database has change.

if user logout system , login again, name display in view changed last update.

i have solution logout , login again after class action update user info. there other solutions without logout?

when user logout , login again, authentication cookie regenerated latest change , user see latest update. can update authentication cookie authenticationresponsegrant method:

var identity = (claimsidentity)user.identity;  identity.removeclaim(identity.findfirst("name")); identity.addclaim(new claim("name", value));  iowincontext context = request.getowincontext(); var authenticationcontext = await context.authentication.authenticateasync(defaultauthenticationtypes.applicationcookie); if (authenticationcontext != null)     authenticationmanager.authenticationresponsegrant = new authenticationresponsegrant(new claimsprincipal(identity), new authenticationproperties { ispersistent = true });
