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.

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();
}

Which one is preferable >object< defined declaratively inside global.asax or static class ?

examples:

VS

public static class classname {}

VS

Application("a") = new classname();

Web Forms :: How To Reference A Master Page Control From A Static Class

Feb 15, 2011

my MasterPage I have a label that reflects the name of the module that the user is currently in. I change the label text accordingly using the following ..

private void ChangePageTitle(string PageTitle)
{
Label lblPageTitle = (Label)Master.FindControl("lblPageTitle");
lblPageTitle.Text = PageTitle;
}

Instead of placing this method in the code-behind of every page, I want to put it in a single class and call it accordingly. I thought of using a static class but do not know how to reference the MasterPage.Can I use a static class? or do I place the method in the code-behind of one page and call Object.Method from the other pages?

May 10, 2010

I am using <%# MyFormatClass(Eval("fieldname")) %> to display data in a grid view on my page. MyFormatClass works fine, but now I want to move it to a central location that can be used by many pages.

Database - Storing Connection In A Static Class?

Mar 4, 2010

Since I'm using Postgresql and can't use LINQ to SQL, I wrote my own wrapper classes.

This is a part of the Student class:

[code]....

It works now! I replaces all Run methods in the Student class with DB.Run

But I want to know if it will work fine with a lot of people online, not me only. I'm not sure how static things work with ASP.NET, maybe it'll eat a lot of memory?..

Way To Generate Links Automatically Via A Static Class

Jun 10, 2010

I would like to generate my links automatically via a static class in each of my aspx pages (or in a common BasePage).Currently I use this:

private const string TEMPLATE =
"~/One.aspx";
public static string Link ()
(
string link = String.Format(TEMPLATE);
return link;
)

But the name of my page, One.aspx is hardcoded. Is it possible to generate the path instead of this hardcoded constant TEMPLATE. You should know that I do not instantiate the class before creating the link.

C# - How To Create A Static Array Containing Custom Class

Jan 6, 2010

I have a method that returns an array of custom class objects that are created by parsing a text file. At the moment every time I use it I am rereading the file which isn't very efficient.

What I wat to do is create an array containing the objects when the page loads and store them in an array which can then be used later.

[Code]....

I thought I could create the static object using something like:

static Album myAlbums[] = readArray("Albums.txt");

but I am getting the following error:

A field initializer cannot reference the nonstatic field, method, or property 'B2M._Default.readArray(string)'

I am new to C# so this is probably something dumb. (Feel free to poke fun in my general direction if this is the case!)

C# - To Use Static Functions If No Class Members Are Needed?

Jan 21, 2011

I have a member function that does not depend on any member variables of the class. (in my case the class is an ASP.Net Page)

The function is protected, I dont need it outside of this class. Its only purpose is to build an URL from an given object.

Should I make all my functions static if they dont depend on the class, even if they are not used outside of this class?

C# - Get The Name Of The Class Without Instantiating Object Or Having A Static Method?

Feb 22, 2011

I hate to see the name of the class used as a string parameter like "FileDownloader" in the code, and I would like to use something like this FileDownloader.Name(), where FileDownloader is name of the class.
Only problem is that I can't find out how to do that without instantiating object or creating a static method...

Is there a way to get a class name in .net without having the object instance and without creating a static method that returns the name of the class?

Web Forms :: Needing To Do A 'simple' ASP.Net Site That Just Uses The Out Of The Box Basics?

Oct 25, 2010

I've been dynamically asigning master pages using code for a number of years as part of a skinning engine. Today however,I'm needing to do a 'simple' ASP.Net site that just uses the out of the box basics.I'm hitting a hurdle though and can't figure why.

[code]...
Now - I want to add an <asp:placeholder> control inside the child page's <Content1> tags - however,the designer's intellisense doesn't show them. If I delete the MasterPageFile tag from the top of the child's page, then all of a sudden it works.Why can't I add a placeholder inside a child form?

Access Static Class Properties From Aspx Page?

Jan 28, 2010

I am on .aspx page and i want to take the width and height of a control from a static class
where i have defined them as constans.

Is there any way to access that class directly from the aspx page?

I know that i can make a method like:

width="<%= getWidthSize() %>"

and inside the aspx.cs to define this method to take the size from that static class.

But i am asking if this could be directly managed from the web aspx page...?
