c# - Generate an image from an HTML code/file in .NET Core 2.x Console Application?

问题描述

I've currently a problem with the NReco.ImageGenerator in a .NET Core 2.x console application that I can't get an image because of course, the console application is not web service at all.

My question now is: Is there a way to use a somehow web service in a console application so I can generate an image from an HTML code/file or is there any other solution to generate an image from HTML code/file in a .NET Core 2.x console application?

Edit

It works on .NET Standard but not on .NET Core. 

var html = string.Format("<h1>Hello World!</h1>");
var converter = new HtmlToImageConverter // Exception happens here
        {
            Width = 250,
            Height = 70
        };
var bytes = converter.GenerateImage(html, NReco.ImageGenerator.ImageFormat.Png);

Exception: 

System.TypeLoadException: Could not load type 'System.Web.HttpContext' from assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

解决方案

我发现NReco.ImageGenerator不支持 .NET Core，对于 .NET Core 我需要支付 LT 版本。但我发现了另一个 NuGet 包，它以某种方式做同样的事情，但我需要自己绘制图像。因此，替代方案是Magick.NET
