以编程方式刷新/更新 HttpContext.User

我正在将 FormsAuthentication 用于 ASP.NET 站点，该站点具有显示当前登录用户 Page.User.Identity.Name 的母版页。

他们可以在设置中更改用户名，当这样做时，我会为他们更新 cookie，这样他们就不必通过回发注销/重新登录。

FormsAuthentication.SignOut();
FormsAuthentication.SetAuthCookie(username, false);

我可能相当挑剔，但在他们更改用户名后，母版页仍然显示其原始用户名，直到他们重新加载或加载不同的页面。

有没有什么方法可以以编程方式更新当前的 Page.User，以便可以在同一回发期间显示他们的新用户名？

I'm using FormsAuthentication for an ASP.NET site that has a master page that displays the current logged in user, Page.User.Identity.Name.

They can change their username in their settings, and when the do so, I update their cookie for them so they wont have to sign out/sign back in with a postback.

FormsAuthentication.SignOut();
FormsAuthentication.SetAuthCookie(username, false);

I'm probably being pretty nit-picky, but after they change their username the master page still displays their original username until they reload or load a different page.

Is there any way to programmatically update the current Page.User, so that their new username can be displayed during the same postback?

虽然MasterMax的建议是我会做的，但您实际上可以通过HttpContext.Current.User更新Page.User。

如果您知道用户的角色（或者您没有使用基于角色的授权），则可以利用 System.Security.Principal.GenericPrincipal 类：

string newUsername = "New Username";
string[] roles = new string[] {"Role1", "Role2"};

HttpContext.Current.User = 
   new GenericPrincipal(new GenericIdentity(newUserName), roles);

Though MasterMax's suggestion is what I would do, you can actually update the Page.User via HttpContext.Current.User.

If you know the user's roles (or you aren't using role based authorization), you can take advantage of the System.Security.Principal.GenericPrincipal class:

string newUsername = "New Username";
string[] roles = new string[] {"Role1", "Role2"};

HttpContext.Current.User = 
   new GenericPrincipal(new GenericIdentity(newUserName), roles);
