Question

I have two lists from which I have to get two values(MyCaption and MyValue).

List<UserInfoModel> userInfo = new List<UserInfoModel>();

List<myuser_field> myUserFields = GetMyUserFields();
var otherUserFields = otherUserService.GetOtherUserFields();

userInfo = (from otherUserField in otherUserFields
               where otherUserField.Chosen == true 
                    select new UserInfoModel {
                        MyCaption = otherUserField.FieldAlias,
                        MyValue =
                    }).ToList();

MyCaption I am directly getting from one of the list. Now to get MyValue I need to find based on otherUserField.FieldName.
i.e I have to find myUserFields.FieldName which is equal to otherUserField.FieldName and assign it to MyValue.

Can it be done in the single query which is as above? Please suggest

Answer 1

userInfo = (from myUserField in myUserFields
            join otherUserField in otherUserFields
            on myUserField.FieldName == otherUserField.FieldName
            where otherUserField.Chosen == true 
            select new UserInfoModel {
                MyCaption = otherUserField.FieldAlias,
                MyValue = myUserField.FieldName
            }).ToList();
