C# webclient cannot download text from web

I am working on a project to get text from this website.
But when I tested it in Visual Studio, I've got some error:

Value cannot be null. Parameter name: solutionDirectory

Here is my code:

using System;
using System.Net;

public class Program
{
public static void Main()
{
WebClient client = new WebClient();
String temp = client.DownloadString("http://www.hkex.com.hk/eng/stat/dmstat/dayrpt/hsio180629.htm");
Console.Write(temp);
}
}

Please use HttpClient Which is very good Option Compare to webClient
And your problem is sounds like your project (vcxproj) file isn't setup properly.

So create New Application Simply and run this Code.

Here you find Actually Difference

Stream client = Task.Run(()=>new HttpClient().GetAsync("http://www.hkex.com.hk/eng/stat/dmstat/dayrpt/hsio180629.htm").Result.Content.ReadAsStreamAsync()).Result;
using (var fileStream = new FileStream("D://data.txt", FileMode.Create, FileAccess.Write))
{
client.CopyTo(fileStream);
}


Full Working Code:-

namespace ConsoleApp2
{
class Program
{
static void Main(string args)
{
Stream client = Task.Run(()=>new HttpClient().GetAsync("http://www.hkex.com.hk/eng/stat/dmstat/dayrpt/hsio180629.htm").Result.Content.ReadAsStreamAsync()).Result;
using (var fileStream = new FileStream("D://data.txt", FileMode.Create, FileAccess.Write))
{
client.CopyTo(fileStream);
}
}
}
}


With Await

namespace ConsoleApp2
{
class Program
{
static void Main(string args)
{
data();
Console.ReadKey();
}
public static async void data()
{
var client = await new HttpClient().GetAsync("http://www.hkex.com.hk/eng/stat/dmstat/dayrpt/hsio180629.htm");
var data= await client.Content.ReadAsStreamAsync();
using (var fileStream = new FileStream("D://data.txt", FileMode.Create, FileAccess.Write))
{
data.CopyTo(fileStream);
}
}
}
}


.Result

Result

Main

static async Task Main(string args){}
