如何 動態編譯自己寫的代碼

CSharpCodeProvider _coder=new CSharpCodeProvider();
   ICodeCompiler complier=_coder.CreateCompiler();
   CompilerParameters _par=new CompilerParameters();
   _par.GenerateExecutable=true;

   _par.OutputAssembly="sy1.exe";//設定應用程式名稱
   _par.MainClass="sy1";//設定主類
   
   _par.IncludeDebugInformation=true;

   foreach(Assembly asm in AppDomain.CurrentDomain.GetAssemblies())
   {
    _par.ReferencedAssemblies.Add(asm.Location);
   }

   string get_Code=_code;

   CompilerResults _res=complier.CompileAssemblyFromSource(_par,get_Code);

   if(_res.Errors.Count>0)
   {
    ErrInfo pEi=new ErrInfo();
    pEi.Show();
    ListBox getList=pEi.getList;
    foreach(CompilerError err in _res.Errors)
    {

     getList.Items.Add(err.ErrorText);
    }
   }
   else
   {
    MessageBox.Show("success");
   }
