linq to sql sub-select - sql

Question

I have two tables that represent say a Mixture and the components of the Mixture. The table layouts are like:
Mixture table:
MixtureID uniqueidentifier
MixtureDescription varchar(50)
Components table:
ComponentID uniqueidentifier
MixtureID uniqueidentifier (FK to previous table)
ComponentName varchar(50)
ComponentRatioPercentage int
Now, what I want to do is take a list of component names inputted from the user and find the ID's of any mixes that contain all of those components.
In SQL I could so something like:
select distinct MixtureID
from Mixture Mixture
where exists (select ComponentName
from Components Components1
where Components1.MixtureID = Mixture.MixtureID and
Components1.ComponentDescription = 'SomeComponentName')
and exists (select ComponentName
from Components2
where Components2.MixtureID = Mixture.MixtureID and
Components2.ComponentDescription = 'SomeOtherComponentName')
and exists....
etc, adding a sub-select for each component.
How would I do something like this in linq to sql? The number of components to look for would not be known in advance, until the user is done with input, though there would be a max of 10. Thanks in advance!

Answer 1

var components = new string[] {"SomeComponentName", "SomeOtherComponentName"};
var query = Mixtures.AsQueryable();
foreach (var component in components)
{
var tmpComponent = component;
query = query.Where(m => m.Components
.Any(c => t.ComponentDescription == tmpComponent)
);
}
var mixturesIds = query.Select(m=>m.MixtureId).Distinct();
