How Can I Validate HTTP (and HTTPS) URLs in C#?

Validating HTTP (and HTTPS) URLs in C#

During the input validation process, it is crucial to verify the validity of the HTTP URL. However, built-in methods such as Uri.IsWellFormedUriString and Uri.TryCreate may recognize non-HTTP file paths as valid URLs.

Solution:

To specifically check HTTP URLs, use the following code:

<code class="language-csharp">Uri uriResult;
bool result = Uri.TryCreate(uriName, UriKind.Absolute, out uriResult) 
    && uriResult.Scheme == Uri.UriSchemeHttp;</code>

This code checks whether the string uriName can be resolved to an absolute URI and ensures that its scheme is specifically "http".

Expands to HTTP and HTTPS:

If the validation should contain both HTTP and HTTPS URLs, please modify the code as follows:

<code class="language-csharp">Uri uriResult;
bool result = Uri.TryCreate(uriName, UriKind.Absolute, out uriResult) 
    && (uriResult.Scheme == Uri.UriSchemeHttp || uriResult.Scheme == Uri.UriSchemeHttps);</code>
