How Can I Efficiently and Securely Combine URLs in .NET?

URL Manipulation within the .NET Framework

Efficient and secure URL path concatenation is essential when dealing with URLs in .NET applications. While Path.Combine excels with file system paths, the .NET framework offers equivalent functionality for URLs.

Utilizing the Uri Class for URL Construction

The Uri class provides a robust method for combining URLs. Its constructor accepts two arguments:

• baseUri: The foundational URL to which the relative path will be added.
• relativeUri: The relative path to be joined with the base URL.

Illustrative Example:

<code class="language-csharp">Uri baseUri = new Uri("http://www.mydomain.com");
Uri combinedUri = new Uri(baseUri, "product/details");</code>

This produces the following concatenated URL:

<code>"http://www.mydomain.com/product/details"</code>

Important Note: It's crucial to understand that the Uri constructor's behavior regarding relative path appending might not always be consistent. It's recommended to explore alternative approaches or thoroughly validate the resulting URI before using it to ensure accuracy.
