使用Linq在foreach循环上的条件

Question

I have a List<KeyValuePair<string, Records> mylist;

I would like to loop in the list foreach different key value. Something like

foreach(var item in myList.select(/\*query the disctinct values of key here ?*/)

is it possible ? How ?

Answer 1

You can do

foreach(var item in myList.Select(x => x.Key).Distinct())
{
    //Your Logic
}

myList.Select(x => x.Key).Distinct() would give you distinct Keys and foreach will loop over them.
