查询具有鲜明和ORDER BY

Question

我有这个数据集

Id  TypeId  Description 
------------------------------- 
1  1   happy 
2  1   sad 
3  2   sad 
4  2   sad 
5  3   upset 
6  1   upset 
7  2   chilaxing 
8  4   happy 

，我试图让LINQ做到这一点：

select count(Id) as count, Type from MyDate 
group by Description 
order by count desc 

所以我得到：

count Type 
------------ 
3  sad 
2  happy 
2  upset 
1  chilaxing 

但是我正在尝试的是没有工作？
