How to use parameter array navigation properties EF linq ?

Question

I have a table structure with relationship in between three tables.

I have added edmx file into my project as below.

 

 

 

I would like to use parameter array navigation properties entity framework using linq.

 

I have written some code in controller like 

<Expression> parames1 = v => v.LoginInfo;
<Expression> parames2 = v => v.LoginInfo.UserDetail;
<Expression> [] paramesArray = new Expression>[] { parames1, parames2 };
var userPost = UnitoffWork.UserPostRepository.GetAll(navigationProperties: paramesArray).Select(u => new HomeViewModel(u));

 I am not able to implement this.

 

getting some errors like

1. parames1 does not exist.

2. can not create an instance of abstarct class or interface 'System.Linq.Expressions.Expression' 

 

Please suggest how can i get all data in single variable from mutliple tables.

Thanks
