The C# language has many powerful features, including the ability to create and manipulate dynamic objects. This post will explain the concept of dynamic objects in C#, provide code samples to demonstrate their use, and discuss the benefits of dynamic objects.
What are Dynamic Objects in C#?
Dynamic objects in C# are objects that allow users to modify their properties and methods at runtime. They have no predefined structure, meaning that their members and methods can be added and removed as needed. This flexibility makes them ideal for scenarios where the structure of the object can change depending on the environment or user input.
Benefits of Using Dynamic Objects in C#
Dynamic objects in C# offer a number of advantages over standard objects. They can be used to quickly prototype an application without having to set up a complex object structure. Additionally, they can be more efficient when dealing with large amounts of data as they don’t need to be initialized at the start. Finally, dynamic objects can also be used to access and manipulate data from other sources, such as databases or web services.
Code Samples
The following code samples demonstrate the use of dynamic objects in C#. The first example shows how to create a dynamic object and add a property to it:
dynamic myObj = new ExpandoObject();
myObj.Name = "John";
The second example shows how to access the properties of a dynamic object:
dynamic myObj = new ExpandoObject();
myObj.Name = "John";
string name = myObj.Name; // name = "John"
Finally, the third example shows how to invoke a method of a dynamic object:
dynamic myObj = new ExpandoObject();
myObj.SayHello = (string name) => {
Console.WriteLine($"Hello, {name}!");
};
myObj.SayHello("John"); // Prints "Hello, John!"
Conclusion
Dynamic objects in C# provide an effective way to quickly prototype applications and access data from other sources. They also offer a number of benefits over standard objects, such as increased efficiency and flexibility. By using the code samples provided in this post, users can begin to take advantage of dynamic objects in their own projects.
The official documentation of Bootstrap 5 is available here.
Bootstrap is one of my favorite open-source CSS frameworks.
What is Bootstrap?
Bootstrap is a free and open-source CSS framework directed at responsive, mobile-first front-end web development. It contains CSS- and JavaScript-based design templates for typography, forms, buttons, navigation, and other interface components.
The journey
Bootstrap 4 is released in Jan 2018. For Bootstrap 5, the team is currently the team working on various aspects like CSS variables, faster javascript, fewer dependencies, and better APIs.
We will get a clear picture of the entire breaking changes details and future list once the beta version released. Now the alpha version available to play around.
Bootstrap 5 alpha no longer depends on jQuery
jQuery played major roles in the earlier versions of bootstrap (let’s say up to 4.x).
Similarly, From Bootstrap version 5, we no longer need jQuery help to use the bootstrap components. Example: maintaining a toggle state, etc.
Now, Bootstrap includes its javascript to do those operations.
Note: Bootstrap dropped jQuery dependency doesn’t mean you can’t use jQuery at all. You can collaborate with jQuery if your project really needs it. It’s just dropped from its official packages to improve the codebase and various aspects.
Bootstrap 5 alpha CDN
Since we have discussed javascript and jQuery, let’s discuss the CDN that needs to be used in boilerplate code.
In Bootstrap 4, we need to import popper.js, jQuery slim, then bootstrap js.
From bootstrap 5, we can simply import only popper.js and bootstrap.js like below
.gutter classes have been replaced with .g* utilities, much like our margin/padding utilities. Team also added options to your grid gutter spacing that matches the spacing utilities you’re already familiar with.
Bootstrap includes six default breakpoints, sometimes referred to as grid tiers, for building responsively. These breakpoints can be customized if you’re using our source Sass files.
Breakpoint
Class infix
Dimensions
X-Small
None
0–576px
Small
sm
≥576px
Medium
md
≥768px
Large
lg
≥992px
Extra large
xl
≥1200px
Extra extra large
xxl
≥1400px
These breakpoints are customizable via Sass—you’ll find them in a Sass map in our _variables.scss stylesheet.
