How to query complex entities

```c#
public role {
  public string id{get;set;}
  public string name{get;set;}
}

public roleClaims{
  public string id{get;set;}
  public string roleid{get;set;}
  public role  role{get;set;}
}
```
How to  select ?
I need to choose. role.name
I do it like this:
`Context.Set<roleClaims>().Select("new{ id, roel.name}")`   but  this is error！
What should I do?
