How to convert an EML Email File to PDF Document in C# .NET Framework

On today’s agenda: converting all of those clunky EML files you’ve got laying around into nice useful PDFs. This would normally take a multi-step process of parsing our EML into HTML, then rendering that and converting the result into PDF. None of that is easy or fun. However, I have an API that I’m going to show you that will take care of all of this for you with a single function call. Let’s look at that.

First we install our client:

Install-Package Cloudmersive.APIClient.NET.DocumentAndDataConvert -Version 3.2.8

Next we call our function with this block of code here:

using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Api;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Client;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Model;
namespace Example
{
public class ConvertDocumentEmlToPdfExample
{
public void main()
{
// Configure API key authorization: Apikey
Configuration.Default.AddApiKey("Apikey", "YOUR_API_KEY");
// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
// Configuration.Default.AddApiKeyPrefix("Apikey", "Bearer");
var apiInstance = new ConvertDocumentApi();
var inputFile = new System.IO.Stream(); // System.IO.Stream | Input file to perform the operation on.
var bodyOnly = true;  // bool? | Optional; If true, the HTML string will only include the body of the email. Other information such as subject will still be given as properties in the response object. Default is false. (optional)
try
{
// Convert Email EML file to PDF document
byte[] result = apiInstance.ConvertDocumentEmlToPdf(inputFile, bodyOnly);
Debug.WriteLine(result);
}
catch (Exception e)
{
Debug.Print("Exception when calling ConvertDocumentApi.ConvertDocumentEmlToPdf: " + e.Message );
}
}
}
}

And that’s really all that needs to be done. Easy.
