Static Class In App_Code?
Jan 8, 2010If a static class is put in App_Code, does that imply only one instance will be created, shared by different http requests?Or each request still brings one request?

View 3 RepliesI have a private static field in my Controller class in an MVC web application.
I have a static method in that controller that assigns some value to that static field, I want to apply lock on that static field until some other instance method in the controller uses the value stored in the static field and then releases it.
DETAILS:
I have a controller named BaseController having a static ClientId field as follows and two methods as follows:-
public static string ClientId = "";
static void OnClientConnected(string clientId, ref Dictionary<string, object> list)
{
list.Add("a", "b");
// I want the ClientId to be locked here, so that it can not be accessed by other requests coming to the server and wait for ClientId to be released:-
BaseController.clientId = clientId;
}
public ActionResult Handler()
{
if (something)
{
// use the static ClientId here
}
// Release the ClientId here, so it can now be used by other web requests coming to the server.
return View();
}
I have a question about C Sharp ASP.NET:Is there a difference (in code speed, resources) between:public static variable declared in public static class MyGlobals in a 'Code File' template;and the variable declared in a normal 'Class File' template;I use this variable in 2 different Class Files and also in _Default Page codebehind cs file.In fact in my case I need about 20 global variables of type List<string>.

View 4 RepliesI am using VS2010 and am creating an ASP.Net application.I have declared a class called "Calculator" in a class file called "Calculator.cs" in the App_Code folder.I have a form called "CalcDemo.aspx" with a code behind file. I try and use the "Calculator" class but intellisense can't see it. I thought App_Code is the common code repository for any classes I define and should be visible to all ASPX code behind files
The namespaces are the same like Webapp1.xxxx
Is there anyway to actually have a class-file placed in any custom directory and still be able to compile it with the application?

this is relatively simple, but how would i go about retrieving the windows login name from the class file in the App_Code folder. I have set up my website to run windows authentication, and can use httpcontext to get windows login name from code beihind, but without passing this to the class everytime, is it possible to get the login name from within the class?
View 2 RepliesSince App_Code doenst exist as an ASP.NET Folder, I manually added App_Code as a regular folder, then within that I placed technologydescriptor.cs. Although it now has the appearance of an ASP.NET Folder.But for some reason my code doesnt recognize this class if its w/in the App_Code folder. This is picked up if it is not within that folder- why?Error: "The type or namespace name could not be found, are you missing a using directive or assembly reference"

I have a PlannerShiftView user control in the root folder of my ASP.NET web site. In my App_Code folder, I have a ShiftViewTemplate class that needs to instantiate a PlannerShiftView (for a TemplateField in a GridView). The problem is, the following code doesn't compile because the PlannerShiftView type is not available in what I deem to be the App_Code 'phantom namespace'.
Please can somebody explain to be what is happening here, as well as what to do. I know I can just move the ShiftViewTemplate out of App_Code, going against convention and without explantion, but that is something of a hollow victory.
I guess I might be missing something easy (or not) here. I have a class in App_Code which do some validations over Session and Request.Url, till here it's working fine. But then I need to get the actual page title. I know it's simple to get it in the page's code behind, but could I get it in a separate class like it is on my scenario?
View 8 RepliesI have a single project. and I have two folder in it. In the 1st folder I have a class named Class1 and in the 2nd folder I have a class named Class2. Can anyone tell me how I can access members of Class1 in Class2. I have tried by adding namespace in Class1 and Using that namespace in Class2. But it is giving error. It is easy to access classes or their members from App_Code folder. I don't want to put my classes in app_code folder.

Correct Syntax :
public static void GetViewStateValue(int StudentID,ViewState MyViewState)
{
if(MyViewState["Name"]!=null)

View 3 RepliesWe have an asp.net website running on IIS 6 Windows 2003. When ever we upload a class file to the App_Code folder our whole site goes down temporarily until, what I assume, compilation is complete. Has anyone else experienced this? Any other file we upload it does not do this only our class files.
View 1 RepliesBest way to describe my issue with vs 2010.create a new website. create the App_Code folder. create a new class in the folder. put the line "x" in the class declaration. hit compile. And the website will compile with no errors. It's not "seeing" this new class as being part of the project best I can tell.
View 1 RepliesI have created a simple ASP.NET Website in Visual Studio 2008. I have a static C# class (lets call it someClass) contained in a separate file in the App_Code folder. I call a method from that class in my page's code behind like so:
someVar = someClass.someMethod(someParam);
This compiles correctly in VS 2008 but when I move it over to my IIS server, I get the following error (CS0103): Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. Compiler Error Message: CS0103: The name 'someClass' does not exist in the current context I have created a virtual directory for this website enabling 'Read', 'Run scripts (such ASP)', and 'Execute (such as ISAPI applications or CGI)'. I am not currently utilizing namespaces (as I thought I would not need to and I'm not sure how to use them properly). What am I doing wrong?
External.dll
IMyClass NewCreated = (IMyClass)Activator.CreateInstance(Namespace.MyClass).UnWrap();
Asp.Net WebSite
App_Code
Namespace.MyClass.cs
Bin
External.dll
Is that even posible? I have tried, a lot of posible combinations, like:
Assembly.GetCallingAssembly().CreateInstance("Namespace.MyClass")
Activator.CreateInstance(AppDomain.CurrentDomain,"Namespace","Namespace.MyClass")
Assembly.GetExecutingAssembly().CreateInstance("Namespace.MyClass")
I've created a new class in App_Code
namespace Site {
public class MyClass {
public MyClass() {
}
}
}
this is my Global.asax.cs
[code]....
The error is in: MyClass myClass = new MyClass();
The type or namespace name 'MyClass' could not be found (are you missing a using directive or an assembly reference?)
