Understand repository functions

Question

Hello Folks,

 

I am learning UnitofWork ,Repository pattern and in the genericrepository.cs file i have a method like this and i am not sure how to use that in real example.

 

 

/// <summary>

/// Include multiple

/// </summary>

/// <param name="predicate"></param>

/// <param name="include"></param>

/// <returns></returns>

public IQueryable<TEntity> GetWithInclude(

System.Linq.Expressions.Expression<Func<TEntity,

bool>> predicate, params string[] include)

{

IQueryable<TEntity> query = this.DbSet;

query = include.Aggregate(query, (current, inc) => current.Include(inc));

return query.Where(predicate);

}

 

for example if we have two repositories rep1,rep2 with a foreignkey relationship will this join two repositories and output it to a list

 

public IEnumerable<CREntity> GetAllCR()

{

var mapper = CreateMapper();

var CRAll = _unitOfWork.Rep1.GetAll().ToList();

//var joinFD = _unitOfWork.Rep1.GetWithInclude(); ---how to add Rep2 using getwithinclude

if (CRAll.Any())

{

var CRModel = mapper.Map<List<ChangeRequest>, List<CREntity>>(CRAll);

return CRModel;

}

return null;

}
