## \#事故现场： ##

在一个.net 4.0 的项目中使用dynamic，示例代码如下：

private static void Main(string[] args)
    {
        dynamic obj;
        obj = new { name = "jack" };
        Console.WriteLine(obj.name);
    }

在读取obj.name时，报错：

> 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?

## \#解决方法： ##

在项目中，添加Microsoft.CSharp.dll的引用；
