一对一导航如何选择表中多个字段关联

[anhuizf1]

比如主表A：treeId, Id 子表B 也有treeId，Id ，如何实现一对一多列映射 （select * from A a left join B b on a.treeId=b.treeId and a.Id=b.Id）
代码如下：
public class A {
public int treeId {get;set;}
public int Id {get;set;}
[Navigate("treeId,Id?")]
public B Son {get;set;}
}

public class B{
public int treeId {get;set;}
public int Id {get;set;}
public string Name {get;set;}
}

是这样配置的

直接：

fsql.Select<A>().Include(a => a.B).ToSql()

不是查，是如何配置多个字段关联

[2881099]

public class A
{
   [Column(IsPrimary = true)]
   public int treeId {get;set;}
   [Column(IsPrimary = true)]
   public int Id {get;set;}

   [Navigate("treeId,Id")]
   public B Son {get;set;}
}

public class B
{
   [Column(IsPrimary = true)]
   public int treeId {get;set;}
   [Column(IsPrimary = true)]
   public int Id {get;set;}

   public string Name {get;set;}
}
