appdomain

问题 I give my production server IP address as App domain in facebook application but it's not saved. It returns error as App domain is not valid. So that I cannot use my facebook connect API. Can we give IP address as App domain in FB application? If it's not, what is the other way to do? 回答1: No, it looks like the app domain can only be a domain and not an ip address. For example in the app settings page, near the App Domain hover the '?' and see: Enable auth on domains and subdomain(s) Also, I

问题 I have a command object, doing work based on a request from a request queue. This particular command will execute its work in a child appdomain. Part of doing its work in the child appdomain involves blocking on a ConcurrentQueue operation (eg, Add or Take). I need to be able to propagate an abort signal through the request queue, across to the child appdomain, and to wake up the worker threads therein. Therefore, I think I need to pass a CancellationToken across the AppDomain boundary. I

问题 First, the question: do CLR specifications guarantee that the code executing in multiple app domains within the same process will share the same address space? By "sharing the address space" I mean that pointers to memory allocated in one of the app domains will be valid for reading and writing across all app domains hosted inside the same process. Consider this self-contained example illustrating the question: the program allocates a Worker object in a separate app domain. The Worker

问题 My goal is to create an executable that will start a shadow copied application. The trick is, I want this starter program to have no external dependencies and not have to contain any knowledge about the program it has to start. I also want it to be the only executable in the directory. In other words, I want it to "run" a .dll assembly not an .exe assembly. (I can require that the name of the .dll file being loaded into a new AppDomain be the same everytime, like Main.dll or something like

问题 I'd like to use an object across AppDomains. For this I can use the [Serializeable] attribute: [Serializable] class MyClass { public string GetSomeString() { return "someString" } } Or subclass from MarshalByRefObject: class MyClass: MarshalByRefObject { public string GetSomeString() { return "someString" } } In both cases I can use the class like this: AppDomain appDomain = AppDomain.CreateDomain("AppDomain"); MyClass myObject = (MyClass)appDomain.CreateInstanceAndUnwrap( typeof(MyClass)

问题 I want to create an application domain with default permissions and load assembly into the application domain with default privileges and execute the methods inside the assembly. 回答1: You may take a look at the following article on MSDN. Or if you want to construct an instance of some type inside another AppDomain (assuming this type has a default constructor): var domain = AppDomain.CreateDomain("NewAppDomain"); var path = @"C:\work\SomeAssembly.dll"; var t = typeof(SomeType); var instance =

问题 I have a Web Application running in one machine and the services in another machine (i.e.both are in different App domains). I have a workflow service in my service layer which gets the Synschronization Context from SynchronizationContext.Current. I get the SynchronizationContext.Current always as null. But If I run both my application and service layer in the same machine (i.e. same appdomain) the SynchronizationContext.Current is AspNetSynchronizationContext and it works fine. Can somebody

问题 Since dynamic assembly loading requires appdomain loading to enable killing the assembly with unloading related appdomain, is there a "max" number appdomains in a process to be loaded? I am thinking of a server based application that each user can run his proprietary C# code dynamically. But what if, say, 2000 users log in and load their codes? Are there any possible restrictions I might encounter besides the number of appdomians? thanks. 回答1: Almost all CLR limits are based on "as memory

问题 I'm fairly new to reflection and I was wonder what I would use a (second) AppDomain for? What practical application would one have in a business application? 回答1: There are numerous uses. An secondary AppDomain can provide a degree of isolation that is similar to the isolation an OS provides processes. One practical use that I've used it for is dynamically loading "plug-in" DLLs. I wanted to support scanning a directory for DLLs at startup of the main executable, loading them and checking
