How Can I Combine URLs in .NET Like Path.Combine?

.NET URL Combination: Mirroring Path.Combine Functionality

.NET's Path.Combine simplifies file path concatenation. A direct equivalent for URLs isn't readily available, but the Uri class provides a suitable solution.

The Challenge: Seamlessly merging base and relative URLs, mimicking Path.Combine's behavior.

The Solution: Leverage the Uri class constructor. It accepts a base Uri and a relative Uri string, intelligently combining them.

<code class="language-C#">Uri baseUri = new Uri("http://MyUrl.com/");
Uri combinedUri = new Uri(baseUri, "Images/Image.jpg");</code>

This yields: "http://MyUrl.com/Images/Image.jpg"

Important Consideration:

The Uri constructor, while effective, can sometimes unexpectedly truncate parts of the base URL. Rigorous testing is vital to ensure the combined URL is as intended.
