使用CodeDom生成程序集

using System;
using Microsoft.CSharp;
using System.CodeDom.Compiler;
using System.CodeDom;

namespace Test.CUI
{
  class Program
  {
    static void Main()
    {
      // 创建编译器对象
      CSharpCodeProvider p = new CSharpCodeProvider();
      ICodeCompiler cc = p.CreateCompiler();

      // 设置编译参数
      CompilerParameters options = new CompilerParameters();
      options.ReferencedAssemblies.Add("System.dll");
      options.GenerateExecutable = true;
      options.OutputAssembly = "HelloWorld.exe";

      //options.ReferencedAssemblies.Add("System.Windows.Forms.dll");
      //options.EmbeddedResources.Add("Data.xml"); // 添加内置资源
      //options.CompilerOptions += " /target:winexe";
      //options.CompilerOptions += " /res:Resource1.res";
      //options.CompilerOptions += " /win32icon:test.ico";
      
      // 创建源码

      // 1. 使用CodeDom创建源码
      //CodeCompileUnit cu = new CodeCompileUnit();
      //CodeNamespace Samples = new CodeNamespace("Samples");
      //cu.Namespaces.Add(Samples);
      //Samples.Imports.Add(new CodeNamespaceImport("System"));
      //CodeTypeDeclaration Class1 = new CodeTypeDeclaration("Class1");
      //Samples.Types.Add(Class1);
      //CodeEntryPointMethod Start = new CodeEntryPointMethod();
      //CodeMethodInvokeExpression cs1 = new CodeMethodInvokeExpression(
      //  new CodeTypeReferenceExpression("System.Console"), "WriteLine",
      //  new CodePrimitiveExpression("Hello World!") );
      //Start.Statements.Add(new CodeExpressionStatement(cs1));
      //Class1.Members.Add(Start);

      // 2. 直接指定源码字符串
      string code = @"
        using System;
        namespace Samples
        {
          public class Class1
          {
            static void Main(string[] args)
            {
              Console.WriteLine(""Hello, World!"");
              Console.WriteLine(DateTime.Now.ToString());
            }
          }
        }
      ";
      CodeSnippetCompileUnit cu = new CodeSnippetCompileUnit(code);

      // 开始编译
      CompilerResults cr = cc.CompileAssemblyFromDom(options, cu);

      // 显示编译信息
      if (cr.Errors.Count == 0)
        Console.WriteLine("\"{0}\" compiled ok!", cr.CompiledAssembly.Location);
      else
      {
        Console.WriteLine("Complie Error:");
        foreach (CompilerError error in cr.Errors)
          Console.WriteLine(" {0}", error);
      }

      Console.WriteLine("Press Enter key to exit...");
      Console.ReadLine();
    }
  }
}
