# C# 

**This document explains how to use C# and .NET's built-in HttpClient and WebProxy to make HTTPS requests through the YumiProxy proxy service and retrieve response data from [ipinfo.io](http://ipinfo.io).**

```csharp YumiProxyDemo.cs lines theme={null}
using System;
using System.Net;
using System.Net.Http;

// ==================== Proxy Configuration (Replace with your actual credentials) ====================
var username = "YOUR_USERNAME";    // Replace with the username from YumiProxy dashboard
var password = "YOUR_PASSWORD";    // Replace with the password from YumiProxy dashboard

// Create a WebProxy instance and set the proxy server address and port
// Replace proxy.yumiproxy.com:9091 with the proxy server (host) and port from YumiProxy dashboard
var proxy = new WebProxy("http://proxy.yumiproxy.com:9091")
{
    Credentials = new NetworkCredential(username, password), // Set authentication credentials
};

// Configure HttpClientHandler to use the above proxy
var handler = new HttpClientHandler
{
    Proxy = proxy,
    UseProxy = true, // Ensure proxy is used
};

// Create HttpClient with the handler
using var client = new HttpClient(handler);

// Send an asynchronous GET request and retrieve the response string
var response = await client.GetStringAsync("https://ipinfo.io/json");

// Output the response content (JSON format)
Console.WriteLine(response);
```

After completing the above steps, you have successfully integrated YumiProxy with your program, providing a safer and more flexible option for network connections.
