In this article, you will learn what is httpclient in c#

In this article, you will learn, how to send/receive data through, C# HttpClient class provides a base class for sending/receiving the HTTP requests/responses from a URL. It is a supported async feature of .NET framework. HttpClient is able to process multiple concurrent requests.

So, some example below links:-

C# HttpClient status code

 

HTTP response status codes provide whether a specific HTTP request has been successfully completed. Responses are grouped in five classes in following code:

 

  • Informational responses (100–199)
  • Successful responses (200–299)
  • Redirects (300–399)
  • Client errors (400–499)
  • Server errors (500–599)

 

using System;
using System.Net.Http;
using System.Threading.Tasks;

namespace usingcsharp
{
    class Program
    {
        static async Task Main(string[] args)
        {
            using var client = new HttpClient();

            var results = await client.GetAsync("https://usingcsharp.com");
            Console.WriteLine(results.StatusCode);
        }
    }
}

 

C# HttpClient HEAD request

The HTTP HEAD method requests the headers that are returned if the specified resource would be requested with an HTTP GET method.

 

using System;
using System.Net.Http;

var url = "https://usingcsharp.com";
using var client = new HttpClient();
var results = await client.SendAsync(new HttpRequestMessage(HttpMethod.Head, url));
Console.WriteLine(results);

 

 

 

C# HttpClient GET request

 

using System;
using System.Net.Http;
using System.Threading.Tasks;

namespace usingcsharp
{
    class Program
    {
        static async Task Main(string[] args)
        {
            using var client = new HttpClient();
            var contents = await client.GetStringAsync("http://usingcsharp.com");
            Console.WriteLine(contents);
        }
    }
}

 

It outputs the simple HTML code of the home page.

C# is a programming language developed by Microsoft that runs on the .NET Framework. C# is used to develop web, desktop, mobile, games and much more application. C# is a object-oriented programming language developed by Microsoft within its .NET Framework. Led by Anders Hejlsberg, your basic C# programming and will also take you through various advanced concepts related to C# programming language. C# such as control statements, objects and classes, inheritance, constructor, destructor, this, static, sealed, polymorphism, abstraction, abstract class, interface, File IO, Collections, namespace, encapsulation, properties, indexer, arrays, strings, regex, exception handling, multithreading etc. For example... using System; namespace MinifyCode { class Program { static void Main(string[] args) { Console.WriteLine("Hello Minify Code"); } } } Output: Hello Minify Code In this article you will learn, what is server side controls. We will discuss each of these objects in due time. In this tutorial we will explore the Server object, the Request object, and the Response object. Session Application Cache Request Response Server User Trace Server Object The Server object in Asp.NET is an instance of the System.Web.HttpServerUtility class. The HttpServerUtility class provides numerous properties and methods to perform many type of jobs. Methods and Properties of the Server object The methods and properties of the HttpServerUtility class are exposed through the intrinsic Server object provided by ASP.NET. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Optimization; using System.Web.Routing; using System.Web.Security; using System.Web.SessionState; using System.Data.Entity; namespace minifycode { public class Global : HttpApplication { void Application_Start(object sender, EventArgs e) { // Code that runs on application startup RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); // Initialize the product database.
