In this guide, we'll show you how to convert raw HTML to PDF using C# and the HttpClient library.
Converting raw HTML content to PDF is useful when you have HTML content that isn't hosted on a web server.
```csharp
using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;
// You can get an API key at https://pdfshift.io
var apiKey = "sk_xxxxxxxxxxxx";
var client = new HttpClient();
client.DefaultRequestHeaders.Add("X-API-Key", apiKey);
var payload = new
{
source = "Hello World
"
};
var json = System.Text.Json.JsonSerializer.Serialize(payload);
var content = new StringContent(json, System.Text.Encoding.UTF8, "application/json");
var response = await client.PostAsync("https://api.pdfshift.io/v3/convert/pdf", content);
// Handle errors:
if (response.StatusCode >= System.Net.HttpStatusCode.BadRequest)
{
throw new Exception($"Request failed with status code {response.StatusCode}");
}
var result = await response.Content.ReadAsByteArrayAsync();
System.IO.File.WriteAllBytes("result.pdf", result);
Console.WriteLine("The PDF document was generated and saved to result.pdf");
```
This allows you to convert HTML content directly to PDF without needing a URL.
