Select the data between tables with many-many relationship using linq query with Entity Framework and C# as shown in the code below:

db.roles.Where(x => x.resource_id == moduleid && x.resource_type == "MyModule" && x.name == "member").SelectMany(x => x.users.Select(u=>u.id)).First();

User and Role entities in the above example have many-many relationship using a join table in the database. The above example selects the User Id with member role.
