LINQ 查询 Grouping By 和 ordering

Question

I have a API service like Google API working with query...Sometimes user type for example "Rio". I have an Enumerable with object with fields

        "city",
        "city_code"
        "country"
        "country_code"
        "rating"
        "type"
        "name"
        "code"

So far so good, I have to order it grouping by City. Plus, if "type" is country it need to appear first than others with same city.

For example:

{
    "city": "Rio De Janeiro",
    "city_code": "RIO",
    "country": "Brazil",
    "country_code": "BR",
    "rating": 3,
    "type": "airport",
    "name": "Santos Dumont",
    "code": "SDU"
},
{
    "city": "Rio De Janeiro",
    "city_code": "RIO",
    "country": "Brazil",
    "country_code": "BR",
    "rating": 2,
    "type": "airport",
    "name": "Galeao Antonio Carlos Jobim International",
    "code": "GIG"
},
{
    "country": "Brazil",
    "country_code": "BR",
    "type": "city",
    "name": "Rio De Janeiro",
    "code": "RIO"
}

In this case, I need to show the type "city" before the type "airport". Sometimes the json come with a lot of data, but I cutted to show here.

If you want to order by 2 properties you can use something like this:

yourList.OrderBy(x => x.City).ThenBy(x => x.Type)
