void UserInfo(Object sender, EventArgs e) 
{
   IPrincipal myPrincipal = this.User;
   String tableString = "<table border=\"1\"><tr><td>Name</td><td>";
   tableString += Server.HtmlEncode(myPrincipal.Identity.Name) + "</td></tr><tr><td>";
   tableString += "AuthenticationType</td><td>" + myPrincipal.Identity.AuthenticationType;
   tableString += "</td></tr><tr><td>IsAuthenticated</td><td>";
   tableString += myPrincipal.Identity.IsAuthenticated + "</td></tr></table>";
   Response.Write(tableString);
}
Sub UserInfo(sender As Object, e As EventArgs)         
   Dim myPrincipal As IPrincipal = Me.User
   Dim tableString As  String 
        tableString = "<table border=""1""><tr><td>Name</td><td>"
   tableString &= Server.HtmlEncode(myPrincipal.Identity.Name) + "</td></tr><tr><td>"
   tableString &= "AuthenticationType</td><td>" + myPrincipal.Identity.AuthenticationType
   tableString &= "</td></tr><tr><td>IsAuthenticated</td><td>"
   tableString &= myPrincipal.Identity.IsAuthenticated.ToString() + "</td></tr></table>"
   Response.Write(tableString)
End Sub

IPrincipal物件代表程式碼正在執行之使用者的安全性內容,包括該使用者的身分識別和其所屬的任何角色。An IPrincipal object represents the security context of the user on whose behalf the code is running, including that user's identity and any roles to which they belong.

這個屬性會使用HttpContext物件的User屬性來判斷要求的來源。This property uses the HttpContext object's User property to determine where the request originates.
