Generating HTML using a template from a .NET application

Question

I have a .NET console application that needs to generate some HTML files. I could just construct the HTML in a StringBuilder and write the contents out to a file, but I was

Here's some code that illustrates a fairly simple way to accomplish what you're trying to do:

using System;
using System.IO;

public class HtmlTemplate
{
    private string _html;

    public HtmlTemplate(string templatePath)
    {
        using (var reader = new StreamReader(templatePath))
            _html = reader.ReadToEnd();
    }

    public string Render(object values)
    {
        string output = _html;
        foreach (var p in values.GetType().GetProperties())
            output = output.Replace("[" + p.Name + "]", (p.GetValue(values, null) as string) ?? string.Empty);
        return output;
    }
}

public class Program
{
    void Main()
    {
        var template = new HtmlTemplate(@"C:\MyTemplate.txt");
        var output = template.Render(new {
            TITLE = "My Web Page",
            METAKEYWORDS = "Keyword1, Keyword2, Keyword3",
            BODY = "Body content goes here",
            ETC = "etc"
        });
        Console.WriteLine(output);
    }
}

Using this, all you have to do is create some HTML templates and fill them with replaceable tokens such as [TITLE], [METAKEYWORDS], etc. Then pass in anonymous objects that contain the values to replace the tokens with. You could also replace the value object with a dictionary or something similar.
