Detailliertes Beispiel dafür, wie asp.net mvc einen Controller dynamisch kompiliert und generiert

using System.Web.Mvc;
using System.CodeDom.Compiler;
using System.Text;
using Microsoft.CSharp;

namespace DynamicCompiler.Controllers
{
  public class HomeController : Controller
  {
    // GET: Home
    public ContentResult Index()
    {
      return Content(@"
              这个页面是vs生成的<br> 
              <a href=&#39;/home/creat&#39;>点击动态编译生成TestController</a><br>
              <a href=&#39;/Test/&#39;>访问TestController</a><br>
              <a href=&#39;/Test/WithView&#39;>测试带View的Action</a>
            ");
    }

    public ContentResult Creat()
    {
      string cspath = Server.MapPath("~/TestController.cs");
      var compiler = CompilerFromCsPath("TestController", cspath); //编译

      #region 输出编译信息
      StringBuilder sb = new StringBuilder();
      sb.Append("cs文件路径：" + cspath);

      sb.Append("编译信息：" + "<br>");
      foreach (string output in compiler.Output)
      {
        sb.Append(output + "<br>");
      }
      sb.Append("错误信息：" + "<br>");
      foreach (CompilerError error in compiler.Errors)
