C＃实体框架-联接lambda查询后返回单个实体的列表

Question

I have two classes:

public class classA
{
    public string keyA {get; set;}
    public string propAA {get; set;}    
    public string propAB {get; set;}
    public string propAC {get; set;}        
}

public class classB
{
    public string keyB {get; set;}
    public string foreignkeyA {get; set;}
    public string propBA {get; set;}    
    public string propBB {get; set;}
    public string propBC {get; set;}        
}

If I do a join between them..

var query = db.ClasseA.
            Join(db.ClasseB, a => a.keyA, b => b.foreignkeyA,
                (ca, cb) => new { ca, cb })
                .Where(q => q.cb.propBC == 'some value')
                .Select();

The result is a combination (list) of classA and classB objects.

But, I need that the result is only a list of class A .

Something like:

List<classA> query = db.ClasseA.
            Join(db.ClasseB, a => a.keyA, b => b.foreignkeyA,
                (ca, cb) => new { ca, cb })
                .Where(q => q.cb.propBC == 'some value')
                .Select(????);

How can I do that??

Answer 1

One example

var query = from obj1 in db.Object1
            join obj2 in db.Object2 on obj1.key equals obj2.somekey
            where obj1.something = "something"
            select obj1

This will join the two but only bring back obj1 items
