How To Read A JSON String From A Webpage?

Question

I am trying to download the contents of this webpage into my program. I have tried using WeblClient.DownloadString, WebClient.DownloadFile, then save it to a file and read it from a local file, but none of this is working. When I use breakpoints in Visual Studio, I see the string is correctly saved, but when I try to print it to a file, or print it to the console, nothing is displayed.

What I am aiming to do is download this webpage's content into a String then parse it with JSON.NET.

Here is my attempt to save it to a file:

         WebClient webpage = new WebClient();


         var html = webpage.DownloadString("https://api.fixer.io/latest");
         String k = html;


          File.WriteAllText(@"C:\Users\JCena\Desktop\Hell1o.txt", k);

The link is borken, But if it return pure JSON You can use RestSharp — blogprogramisty.net

You code is almost fine. first, get rid of the "new" keyword. second, make sure you don't have exception for permissions for the folder specified.

try that code:

     WebClient webpage = new WebClient();

     var html = webpage.DownloadString("https://api.fixer.io/");
     String k = html;

     File.WriteAllText(@"Hello.txt", k);

Thanks for helping me out! The "new" isn't actually in my code, I accidently copy pasted the wrong line and forgot to edit it out :P

Does it work for you now? If it is the answer you were looking for, mark it as "answer". otherwise, help me help you :)

No :( No file is being written for some reason. Any idea?

What exception are you getting?

Ok, so I rebooted Visual Studio as an admin and that seemed to work. Seeing as your code worked, I will mark yours as the solution :)
