Well in that case, you can create a class that holds those properties or try casting it to dto type in return statement or you can change the return type of this method to object and in your callinge method try casting object to dto type.

Hi Ravi Patel,
i tried the way as shown but EncounterUserDto has different Properties.
i have taken alias for that properties.

not able to return the anonymous types

Hi ,

its throwing error beacuse your method return type is EncounterUserDto but you are returning anonymous type

try this

i am assuming that EncounterUserDto is a class which contain the following property

userRoleId
userUserId
roleRoleId
roleValue
public EncounterUserDto GetUserRolesByUserId(Guid userId)
{
var userRolesList = from u in _unitOfWork.Repository().GetEntityAsQuerable()
join r in _unitOfWork.Repository().GetEntityAsQuerable()
on u.RoleId equals r.RoleId
select new EncounterUserDto
{
userRoleId = u.RoleId,
userUserId = u.UserId,
roleRoleId = r.RoleId,
roleValue = r.Value
};
return userRolesList;
}
if you tell me the exact type of EncounterUserDto then i can fix the issue

It seems that you are trying to create a list of anonymous type ( where you are doing select new {} ) but your method is expected to return the DTO of type EncounterUserDto.

If you take care of creating object of type EncounterUserDto, it should work fine. Try doing select new EncounterUserDto { properties}.
