问题 In an ASP.NET 3.5 application running on IIS, how do I force a "deauthentication" of all currently logged-in and authenticated users? iisreset didn't seem to do the trick! 回答1: ASP.NET authentication is designed to be resilient to an IISReset due to its use of cookies - performing an IISReset will clear any in-memory information, but the next time a user asks for a page on your site, they will send their authentication token, which (if it hasn't timed out) will still be valid, and the server

问题 I am creating a new MVC 4 app for a client that I had previously created ASP.Net 3.5 (VS 2008) apps for. I created a gateway app to launch several other ASP.Net 3.5 web apps , with the gateway app handling the login and the forms authentication ticket. As long as all of the other web apps have the same settings for the forms authentication and machine key sections all other apps were able to use the forms auth objects to see if the user was authenticated. I am now creating a new MVC 4 app

问题 I have a control which is repeated several times in a page. I'd like each occurrence to have a unique ID which I will define (not the horrible ID asp.net attaches). The problem is that I will only know the ID in run time. I'd like in the .aspx to write the following: <uc8:MyControl ID="<%=THEID%>" runat="server" /> but I know it doesn't work. What's the right way to approach this? Thanks a lot! 回答1: You may add with code: MyControl control = new MyControl(); control.ID == "myControl" + count

问题 I've noticed on a few tutorials online that when a new ASP.NET Server Control is added, it automatically includes Properties folder (containing AssemblyInfo.cs) and a References folder. This works fine for me when creating a C# Server Control, but in VB.NET I just get a template .vb file and a Project file. Why is this and how can I get an AssemblyInfo.vb file? 回答1: AssemblyInfo.vb file is created for every project. By default it is not displayed in the Solution/Project Explorer. To view this
