Fetch contents from a URL into a string in C#

This article illustrates the different techniques to fetch contents from a URL into a string in C#.

1. Using `WebClient` class

To download the requested resource as a string, you can use the WebClient.DownloadString() method from the System.Net namespace. It takes the string containing the URI to download and returns a string containing the contents of the requested resource.

using System;

using System.Net;

public class Example

{

public static void Main()

{

String url = "https://code.jquery.com/jquery-3.6.0.min.js";

string s;

using (WebClient client = new WebClient()) {

s = client.DownloadString(url);

}

Console.WriteLine(s);

}

2. Using `HttpClient` class

The recommended option is to use the HttpClient class from the System.Net.Http namespace. The HttpClient class provides the GetStringAsync() method, which sends a GET request to the specified Uri and asynchronously returns its content as a string.

using System;

using System.Net.Http;

public class Example

{

public static void Main()

{

String url = "https://code.jquery.com/jquery-3.6.0.min.js";

string s;

using (HttpClient client = new HttpClient())

{

s = client.GetStringAsync(url).Result;

}

Console.WriteLine(s);

}

3. Using `WebRequest` class

Finally, you can use the WebRequest.GetResponse() method to send a request to a resource and get a response. Here’s what the code would look like:

using System;

using System.Net;

using System.IO;

public class Example

{

public static void Main()

{

String url = "https://code.jquery.com/jquery-3.6.0.min.js";

using (StreamReader reader = new StreamReader(WebRequest.Create(url)

.GetResponse().GetResponseStream()))

{

String s = reader.ReadToEnd();

Console.WriteLine(s);

}
