How to get current page URL in MVC 3

📝🤔 Hey there tech enthusiasts! Today I'm going to help you solve a common problem in MVC 3: getting the current page URL. 🌐

So, imagine you're building a neat blog with a Facebook comments plugin. Everything is working fine, but you need to pass the current, fully-qualified URL to the plugin. How do you do it? Let's find out! 💡

🔍 First, let's take a look at the code snippet provided:

<div style="width: 900px; margin: auto;">
    <div id="fb-root"></div>
    <fb:comments href="URL HERE" num_posts="10" width="900"></fb:comments>
</div>

As you can see, there is a placeholder for the URL. But how do we dynamically insert the actual URL? 🤔

🚀 The solution is simpler than you might think! We can leverage the @Request.Url.AbsoluteUri property from the MVC 3 framework. This property gives us the complete URL of the current page. 🌟

Here's how you can modify your code to include the current page URL:

<fb:comments href="@Request.Url.AbsoluteUri" num_posts="15" width="900"></fb:comments>

By using @Request.Url.AbsoluteUri, we are now dynamically passing the correct URL to the Facebook comments plugin based on the current page the user is on. 🎉

💡Remember, this solution assumes you're using the Razor view engine in MVC 3. If you're using a different view engine, make sure to adjust the syntax accordingly.

So there you have it! You can now easily get the current page URL in MVC 3. 🙌
