LINQ Unable to get distinct value from many to many Entity Framework

I am using linq to query many to many relationship
I have those tables/entities :
Each order has multiple products and I want to get distinct order with products.
Here is my query:
var query = (from order in db.Order
join orderproduct in db.OrderProduct
on order.orderId equals orderproduct.OrderId
join product in db.Product
on orderproduct.ProductId equals product.productId
select new
{ order.orderId,
order.name,
product.productId,
product.productName,
product.price
}).Distinct().ToList();
This is the result :
I want to get only name "Jane" with 2 products. The result is showed 2 records with same name "Jane".
How to get one record name "jane" and 2 products?
Thanks for your help.

use the following:
var query = (from order in db.Order
join orderproduct in db.OrderProduct
on order.orderId equals orderproduct.OrderId
join product in db.Product
on orderproduct.ProductId equals product.productId
select new {order.orderId,order.name,product.productId,product.productName,product.price}).GroupBy(order=>order.orderId).ToList();

If you want to return a structure containing the customer's name and its ordered products, I recommend to group the products by order.orderName (not order.orderId) and to load the result into a dictionary:
var query = from order in db.Order
join orderproduct in db.OrderProduct on order.orderId equals orderproduct.OrderId
join product in db.Product on orderproduct.ProductId equals product.productId
group product by order.orderName into orderGroup
select orderGroup;
var orderedProductsByName = query.ToDictionary(name => name.Key, products => products.ToList());

This is my SQL query that is used to retrieve the sum of quantity where product has same id, I want to use it in LINQ

This is my SQL query that is used to retrieve the sum of quantity where
product has same id, I want to use it in LINQ.
select p.ProductId,s.TotalQuantity,p.Title from Products p
join (SELECT ProductId, SUM(Quantity) AS TotalQuantity
FROM SalePerProduct s join Invoices i on s.InvoiceId = i.InvoiceId
where i.IssueDate like '%2016%'
GROUP BY s.ProductId) s
on s.ProductId = p.ProductId;
I have Tried this LINQ query but it does not work fine, It sums up the quantity having same product id but i am unable to show product title using this, need some help.
Thank you in advance.
var sales = from sale in db.SalePerProducts
join product in db.Products
on sale.ProductId equals product.ProductId
where sale.ProductId == product.ProductId
group sale by sale.ProductId into g
select new
{
ProductId = g.Key,
Sum = g.Sum(sale => sale.Quantity),
};

Here is the answer, finally i am able to retrieve multiple products with same name and PRODUCT_ID as a single record ans also sums up the quantity, Thankyou all of you.
Please vote up if you find this useful
var sales = from sale in db.SalePerProducts
join product in db.Products
on sale.ProductId equals product.ProductId
join invoice in db.Invoices
on sale.InvoiceId equals invoice.InvoiceId
where sale.ProductId == product.ProductId &&
invoice.IssueDate.Date == date
group sale by new { sale.ProductId,product.Title } into g
select new
{
ProductId = g.Key.ProductId,
Product_Title = g.Key.Title,
Quantity_Sold = g.Sum(sale => sale.Quantity)
};

var sales = from sale in db.SalePerProducts
join product in db.Products
on sale.ProductId equals product.ProductId
group new {sale, product} by sale.ProductId into g
select new
{
ProductId = g.Key,
Title = g.FirstOrDefault().product.Title,
Sum = g.Sum(s => s.sale.Quantity),
};
I removed unnecessary where clause, you have in your version.

Multiple join with groupby in linq

i have 5 table from which i want to get some information using linq.i am using following query for reading data from data .
var query = (from GRD in _tblStudents.GetQueryable()
join apt in _tblApplicants.GetQueryable()
on GRD.ApplicantID equals apt.ApplicantID
join cls in _tblClasses.GetQueryable()
on GRD.CityID equals cls.ClassID
join prg in _tblPrograms.GetQueryable()
on cls.ProgramID equals prg.ProgramID
join city in _tblCities.GetQueryable()
on GRD.CityID equals city.CityID
where GRD.AcademicYearID == yearId && cls.ProgramID == programId
group apt by new{apt.Gender} into grouped
select new CityWiseStudentModel
{
CityName=city.CityName,
//'city' does not exist in the current context
Gender = grouped.Count(),
programName=prg.Program,
//'prg' does not exist in the current context
}
);
How i can get City name from city table and program name from prg table

group <--> by <--> into <--> is changed your scope to IGrouping<a,b>
My opinion is not only apt.Gender is your key but city.CityName and prg.Program
try this (or some similar):
group apt by new{apt.Gender, city, prg} into grouped
select new CityWiseStudentModel
{
CityName = grouped.Key.city.CityName,
Gender = grouped.Count(), //rename GenderCount
programName = grouped.Key.prg.Program,
// Gender = grouped.Key.Gender,
}

Remember that grouped will only hold the things you've grouped. If you only group adt, then city and prg will not be available in your select.
So you'll need to:
Include city and program into grouped (otherwise they're not available)
Access CityName and Program inside the grouped collection
Something like this should do the trick:
...
group new { apt, cls, prg, city } by new{apt.Gender} into grouped
select new CityWiseStudentModel
{
CityNames = grouped.Select(g => g.city.CityName),
...
programNames = grouped.Select(g => g.prg.Program)
}

How to select CompanyName and number of its products?

I want to write a Linq query that will return, columns with CompanyName of Supplier and number of all products of this company. Can you help me?
So far I got this:
var company = from pro in db.Products
join sup in db.Suppliers
on pro.SupplierID equals sup.SupplierID
group pro by pro.SupplierID
into g
select new { Name = g.Key, COUNT = g.Count() };
But this returns SupplierID not CompanyName. Database is Northwnd.

Use group join (i.e. join...into) to join suppliers with products and get all products of supplier in group:
from s in db.Suppliers
join p in db.Products
on s.SupplierID equals p.SupplierID into g
select new {
s.CompanyName,
ProductsCount = g.Count()
}

The following compiles and runs with Linq-for-objects. I can't vouch for whether Linq-to-SQL will cope.
var company = from sup in db.Suppliers
select new
{
Name = sup.CompanyName,
COUNT = db.Products
.Where(pro => pro.SupplierID == sup.SupplierID)
.Count()
};

SQL Query selecting where there are more than 3 distinct

I am having problems with a SQL query, i need a list of consumers having purchased at least 3 different products whose suppliers are from a certain city (Lets say new york).
Tabels Columns:
Tb_Consumer..........Con_ID(PK), Name, City
Tb_Supplier.............Supp_ID(PK), Name, City
Tb_Transactions.....Tran_ID(PK), Supp_ID(FK), Con_ID(FK), PROD_ID(FK)
Tb_Products............Prod(ID(PK), Name
What i have so far:
var query8Result = (from c in context.Tb_Consumer
join t in context.Tb_Transactions on c.Con_ID equals t.Con_ID
join s in context.Tb_Supplier on t.Supp_ID equals s.Supp_ID
join p in context.Tb_Product on t.Prod_ID equals p.Prod_ID
where s.City == "New York"
select new { Name = c.Name }).Distinct();

I think you need a few Group-by's
var query8Result = (from c in context.Tb_Consumer
join t in context.Tb_Transactions on c.Con_ID equals t.Con_ID
join s in context.Tb_Supplier on t.Supp_ID equals s.Supp_ID
join p in context.Tb_Product on t.Prod_ID equals p.Prod_ID
where s.City == "New York"
group c by new { c.Name, t.Prod_ID } into customerProducts
group customerProducts by new { customerProducts.Key.Name } into customers
where customers.Count() > 3
select g.Key);
Sorry if this isn't 100% correct - It's a little hard to test this...
