"One or more types required to compile a dynamic expression cannot be found. Are you missing referen

#事故現場：

　　在一個.net 4.0 的項目中使用dynamic，示例代碼以下：

1 private static void Main(string[] args)
2 {
3     dynamic obj;
4     obj = new { name = "jack" };
5     Console.WriteLine(obj.name);
6 }

　　在讀取obj.name時，報錯：

One or more types required to compile a dynamic expression cannot be found. Are you missing references to Microsoft.CSharp.dll and System.Core.dll?

#解決方法：

　　在項目中，添加Microsoft.CSharp.dll的引用；
