asp.net - Diffplex 入门

Question

我想突出显示 asp.net 中两个文件之间的差异。经过网络搜索，我选择了 Diffplex APi。我是一个初学者。我需要一些关于如何实现它的指导？我已经添加了引用库，这就是我能理解的全部。没有任何 Api 文档。我以前没有使用过Apis。

这是“文档”(即源代码)中的一个简单示例，可以帮助您入门。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using DiffPlex;
using DiffPlex.DiffBuilder;
using DiffPlex.DiffBuilder.Model;
using System.Text;


namespace DiffPlexTest.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            StringBuilder sb = new StringBuilder();

            string oldText =  @"We the people
                of the united states of america
                establish justice
                ensure domestic tranquility
                provide for the common defence
                secure the blessing of liberty
                to ourselves and our posterity";
            string newText = @"We the peaple
                in order to form a more perfect union
                establish justice
                ensure domestic tranquility
                promote the general welfare and
                secure the blessing of liberty
                to ourselves and our posterity
                do ordain and establish this constitution
                for the United States of America";

            var d = new Differ();
            var builder = new InlineDiffBuilder(d);
            var result = builder.BuildDiffModel(oldText, newText);

            foreach (var line in result.Lines)
            {
                if (line.Type == ChangeType.Inserted)
                {
                    sb.Append("+ ");
                }
                else if (line.Type == ChangeType.Deleted)
                {
                    sb.Append("- ");
                }
                else if (line.Type == ChangeType.Modified)
                {
                    sb.Append("* ");
                }
                else if (line.Type == ChangeType.Imaginary)
                {
                    sb.Append("? ");
                }
                else if (line.Type == ChangeType.Unchanged)
                {
                    sb.Append("  ");
                }

                sb.Append(line.Text + "<br/>");
            }

            ViewData["old"] = oldText;
            ViewData["new"] = newText;
            ViewData["result"] = sb.ToString();

            return View();
        }
    }
}
