LINQ Case statement within Count

Can you help me translate this sql into Linq please:

select 
    count(case when t.TypeID = 1 then t.TypeID end) as 开发者_如何学Pythona,
    count(case when t.TypeID = 2 then t.TypeID end) as b,
    count(case when t.TypeID = 3 then t.TypeID end) as c
from myTable t

I've searched the internet and found some similar sql but nothing that fits this scenario. Is it possible?

Thanks

I think you want something like this

var query = new
            {
              a = (context.MyTable.Where(t => t.TypeID == 1).Count(),
              b = (context.MyTable.Where(t => t.TypeID == 2).Count(),
              c = (context.MyTable.Where(t => t.TypeID == 3).Count(),
            }

Edit - If you want it all in one query you could do this:

var query = from x in context.MyTable
            group x by 1 into xg
            select new
            {
              a = xg.Where(t => t.TypeID == 1).Count(),
              b = xg.Where(t => t.TypeID == 2).Count(),
              c = xg.Where(t => t.TypeID == 3).Count(),
            };
