C# Download PDF from URL 2023.6.10

You can use the 'WebClient' class or 'HttpClient' to fetch the PDF file. Create an instance of either class and use the 'DownloadFile' or 'GetAsync' method.

You need to include the 'System.Net' namespace for 'WebClient' and the 'System.Net.Http' namespace for 'HttpClient'.

Yes, you can use the following code: ```csharp using System.Net.Http; using System.IO; static async Task DownloadPdf(string url, string outputPath) { using (HttpClient client = new HttpClient()) { var response = await client.GetAsync(url); if (response.IsSuccessStatusCode) { using (var fs = new FileStream(outputPath, FileMode.Create, FileAccess.Write)) { await response.Content.CopyToAsync(fs); } } } } ```

You should handle exceptions like 'HttpRequestException', 'IOException', and general 'Exception' to catch issues such as network errors or file write errors.

Yes, you can use asynchronous methods like 'GetAsync' with async/await syntax in your download implementation.

There is no specific size limit enforced by C#, but you may run into limitations based on your network speed or memory availability.

Make sure your application has the necessary permissions, especially if you are running it in an environment with restricted internet access.

Yes, you can specify custom headers using HttpRequestMessage or by setting default headers on an instance of HttpClient.

You will need to include the necessary authentication information such as tokens or credentials in your request headers.

You can save it to any directory where your application has write access. Common practice is to save it in a designated folder for downloads.
