Hello:

1) Create your WebApi's class something like this following:

public class GetController : ApiController
    {
        private const string OUTPUT_FORMATION = "Your name is:{0},Password is:{1}";
        public string Get(string name, string password)
        {
            return string.Format(OUTPUT_FORMATION, name, password);
        }
    }

2) Then create another console app, with the "HttpClient"'s asynchornized method like this following:

using System;
using System.IO;
using System.Net.Http;
 
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            UriBuilder builder = new UriBuilder("http://localhost:6598/api/get");
            builder.Query = "name='abc'&password='cde'";
 
            //Create a query
            HttpClient client = new HttpClient();
            var result = client.GetAsync(builder.Uri).Result;
 
            using (StreamReader sr = new StreamReader(result.Content.ReadAsStreamAsync().Result))
            {
                Console.WriteLine(sr.ReadToEnd());
            }
        }
    }
}

Hi KaptinKoda，

Please how do I call this Get() method using HttpClient

Code below is for your reference:

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri("http://localhost:9000/");
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

    // New code:
    HttpResponseMessage response = await client.GetAsync("api/products/1");
    if (response.IsSuccessStatusCode)
    {
        Product product = await response.Content.ReadAsAsync>Product>();
        Console.WriteLine("{0}\t${1}\t{2}", product.Name, product.Price, product.Category);
    }
}

Please refer to below articles for details and demo :
