Reading a web page in C#
last modified January 4, 2023
In this article, we show how to get a web page in C#.
The article shows how to read a page using,
WebClientare obsolete, they should not be used anymore for HTTP requests.
In the examples of this tutorial, we read a web page from a small webpage webcode.me.
C# read web page with HttpClient
HttpClient provides a base class for sending HTTP requests and
receiving HTTP responses from a resource identified by a URI.
using var client = new HttpClient(); client.DefaultRequestHeaders.Add("User-Agent", "C# console program"); var content = await client.GetStringAsync("http://webcode.me"); Console.WriteLine(content);
The code example scrapes a web page asynchronously using the
HttpClient is a modern way of fetching web
pages in .NET.
var content = await client.GetStringAsync("http://webcode.me");
await operator takes an awaitable as an argument; it examines
if awaitable has already completed; if the awaitable has already completed, then
the method continues running. The
GetStringAsync reads the
content to a string as an asynchronous operation.
$ dotnet run <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>My html page</title> </head> <body> <p> Today is a beautiful day. We go swimming and fishing. </p> <p> Hello there. How are you? </p> </body> </html>
C# read web page with Flurl.Http
Flurl.Http is a fluent, portable, testable HTTP, third-party client library for the C# language.
$ dotnet add package Flurl.Http
We install the
string result = await "http://webcode.me".GetStringAsync(); Console.WriteLine(result);
The example reads a small web page and prints its contents to the terminal.
string result = await "http://webcode.me".GetStringAsync();
await operator is applied to a task in an asynchronous method
to suspend the execution of the method until the awaited task completes. The
task represents ongoing work. The data is retrieved with the
GetStringAsync extention method.
Reading a web page with RestSharp
RestSharp is a simple REST and HTTP API client for .NET. It is a third-party library.
$ dotnet add package RestSharp
We install the
using RestSharp; var client = new RestClient("http://webcode.me"); var request = new RestRequest(); var res = await client.ExecuteGetAsync(request); Console.WriteLine(res.Content);
The code example gets the contents of a web page using RestSharp library. The web page is downloaded asynchronously.
var client = new RestClient("http://webcode.me");
A rest client is created with the
var request = new RestRequest();
A request is created with
RestRequest; the default is a GET
var res = await client.ExecuteGetAsync(request);
The request is executed asynchronously using the
The content of the response is printed.
