如何以这种方式遍历此列表？

Question

我有一个对象列表,如下所示:

ID:2000
Title:"Title 1"
Description:"My name is Marco"

ID:2000
Title:"Title 2"
Description:"My name is Luca"

ID:3000
Title:"Title 3"
Description:"My name is Paul"

ID:4000
Title:"Title 4"
Description:"My name is Anthony"

ID:4000
Title:"Title 5"
Description:"My name is Carl"

ID:4000
Title:"Title 6"
Description:"My name is Jadett"

现在,我想用每个浏览(遍历)它.但我想从相同的ID开始遍历它.因此,首先是单个/唯一ID(2000,3000,4000,所以3个步骤)的foreach.对于每个"ID"步骤,每个标题/描述:对于ID 2000为2个步骤,对于ID 3000为1,对于ID 4000为3.列表按ID排序.

我该怎么做？通过...分组？呃... ...

Answer 1

是的,有一个小组:

foreach (var group in items.GroupBy(i => i.ID))
{
    foreach (var item in group)
    {
    } 
}
