Multiple ForEachs, Possible To Avoid With LINQ?

Question

I am wondering about getting rid of some nested foreach's in my code using LINQ. For example, assume the following code:

                  
  IEnumerable<MyObject1> MyObject1Collection = SomeCollection.Cast<MyObject1>()
                    foreach (MyObject1 obj1 in MyObject1Collection)
                    {
                        foreach (MyObject2 obj2 in MyObject1.MyObject2Collection)                           {                           

if (MyObject2.IsFalse)
{
// Do Stuff
}

}
                    }

Is there a better way to do this with LINQ?

TIA!
