C# Dynamic Linq/Queries

UPDATE2 I started playing more with James suggestion of using reflection and got something working that will return a property value based on a string variable. I don't want to put this as an answer just yet though as I feel it is probably not the best solution. Here is the code:

DataContext dataBase = new DataContext();
List<string> listOfFields = new List<string>;
List<string> listOfUsers = new List<string>


//strFields and strNames are strings generated from listOfFields and listOfUsers
IEnumerable<myUserData> userInfo = dataBase.ExecuteQuery<myUserData>
                       ("select " + strFields + " from myUserData where user_id                          in (" + strNames + ")");    

foreach(var user in userInfo)
{
    foreach(string field in listOfFields)
    {
        string fieldValue = user.GetType().GetProperty(field).GetValue(user,null).ToString
        Console.WriteLine(fieldValue);
    }

}

UPDATE: I am making progress! I think. This could be a very terrible solution and resource hog, I'm not sure yet, but it's better than the blank screens I've been getting. The issue now is finding a way to just return the values and not the field name with it. Here is my code:

foreach(string userID in listOfUserIDs)
{
    //dataBase is a Datacontext
    var userInfo = dataBase.myTable
                   .Where("user_id == @0", userID)
                   .Select("New(" + strFields + ")");

    foreach(var user in userInfo)
    {
         Console.WriteLine(user);
    }
}

This outputs {first_name = JOHN, last_name = DOE} etc whatever other fields. I'm hoping I can find a way to modify my Select clause to just select the values.
