private static Dictionary<string, string> emailCache = new Dictionary<string, string>();
protected string GetUserEmail(string accountName)

C# - Delete Entries In Static Dictionary When Not Used?

Jul 3, 2010

I have a static class that holds a dictionary of objects. I have multiple threads that access this dictionary and create objects on it that are specific to that thread. How and when can I remove entries from the dictionary when a thread is "done"?

Basically this is a static class for an ASP.NET application that all requests can have "isolated objects" (that are related to the current thread) created in the dictionary. But, I don't really want to be tied to ASP.NET.

C# - Static Vs Member Field Revisited / Want To Persist A Large Dictionary Of Strings Inside The Memory?

Feb 18, 2011

I need an advice on piece of functionality that I am ought to implement. The scenario is that we haven an HttpHandler which servers to intercept file uploads. In the handler, I need to persist a large dictionary of strings inside the memory. The dictionary might be as large as 100 entries. I am wondering whether it is safe to store that in a static variable, so that it is not initialized every time instance of the handler is created (there will be a lot of instance for sure). In general, what is the approach in such scenarios. Is it a generally better idea to use static fields, to persist data that will not be changed?

C# - How To Lock A Private Static Field Of A Class In One Static Method

Mar 26, 2011

I 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.


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();

Best Practices For Using MVC With A Dictionary-like Model?

Feb 11, 2011

I'm about to begin an ASP.NET MVC project and I'm not sure how to approach an aspect of the design. Basically, there is a user site and an admin site. In the admin sites, administartors design a form and send an e-mail link out to a handful of people. When the users click on the link, they are sent to the form.

Essentially what I'm wondering is what are the best practices when the model resembles looks more like a dictionary than a table?

In other words, instead of:

CREATE TABLE FormResponse (ResponseId, FormId, UserId, FirstName, LastName, BirthDay, Comments)

...containing 1 row per complete response

It's more like:

CREATE TABLE FormResponse (ResponseId, FormId, UserId, QuestionId, Value)

...containing 4 rows. 1 for the FirstName, 1 for the LastName, 1 for the BirthDay, and 1 for Comments.

MVC :: Modify The Routes Dictionary?

Feb 16, 2010

how to do routing. My problem basically relates to "logged in" and "logged out routes" and having both as "/".

i.e. I have home/index for logged out user which appears as "/" but this has got me confused as to how I can have home/home for logged in user and still have "/".

I keep getting

I could modify like - but I want it like "/". My confusion relates to the fact that the "/" [] is bound in the routes collection to home/index.

how I can modify the routes dictionary (which will be binded ONCE at the start) so that the "/" can be shared for logged and non-logged users ?

C# - Bind A Dictionary To A Gridview?

Jan 7, 2011

Is it possible to automatically bind a Dictionary to a Gridview? The closest I've got is:

Dictionary<string, myObject> MyDictionary = new Dictionary<string, myObject>();
// Populate MyDictionary here.
Grid1.DataSource = MyDictionary.Values;

This binds the properties in myObject to the gridview, but I'd like to get the key as well. If it's not possible, is there an alternative, e.g. use a repeater?

C# - Storing Dictionary In Session?

Jan 29, 2011

How do you create a dictionary of objects in the session? More specifically, I have a list of objects: MyList stores MyObject as the result of a linq query with the date as a parameter.

List<MyObject> Mylist;
MyList = GetObjects(TheDate);

Now I'd like to store MyList in the session object in a dictionary with the date as the key. When the page needs a MyList for a specific date, first search the dictionary and if it's blank for that date, get the data from the GetObjects query and store the result in the dictionary in the session.
