The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

LINQ Query by Name

Asked by veruthandai in MS SQL Server, Language Integrated Query - LINQ

Tags: LINQ

I have three tables...

Elements
- Id
- Name

Keys
- Id
- ElementId
- Value
- UserId

Users
- Id
- Name

What I basically want to do is to figure out a way to call item.Keys["Element Name"].Value so that I can use the Keys like an indexing system. Any ideas on a LINQ query that would express this?

It's kind of difficult to express. Essentially I need to get the index of the Keys as it is attached to another table where the Element.Name is equal to the expression.

So let's assume..

Users
1 - "Stacey"

Elements
1 - "Age"

Keys
1  - 1 - 25 - 1

In my Model, I would see

item.Keys[ -index can go here to get the key- ].Value

I'm trying to find the best way to lookup the Index based on the Label I want. I am using the Elements table between Keys and Tags to enforce non-duplication due to typos and case-sensitivity. So the Elements is behaving like a dictionary of valid Key and Tag names.

I know of the .Single( e => Element.Name == "Age") approach, but I cannot seem to figure out how to translate this into the index filed. The problem is that the array will not always be indexed the same for every single user. Some of them might have "Age" at index 0, some might have it at Index 37.
