Custom Orderby/ThenBy

Question

I'm not sure if this is possible, I'm trying to order/sort/rearrange a data:

  TYPE    NAME   CODE
     1     AAA      7
     1     BBB      8  
     5     CCC      6
     4     DDD      5
     1     EEE      7
     1     DDD      8

into like this:

  TYPE    NAME   CODE
     1     AAA      7
     1     EEE      7
     4     BBB      1
     5     CCC      6
     1     BBB      8 
     1     DDD      8

sorted by type then by name, but if code = 8 then it should be at last.

code:

 SomeList.OrderBy(c => c.Type).
  ThenBy(c => c.Name).
  ThenBy(c => Code);

Answer 1

You can use this "conditional sorting". It's important that the code check comes first:

var query = SomeList
    .OrderBy(c => c.Code == 8 ? 1 : 0)
    .ThenBy(c => c.Type)
    .ThenBy(c => c.Name);
