LINQ中的反射bool属性

Question

I want to use reflection to write this code better. I now have the IsSearchable and IsEditable functions, but can I refactor this code to get the part c.Searchable and c.Editable out?

I have 10 functions like this and only need one. The only different part is what bool property to check, c.Searchable or c.Editable .

  bool searchable = conditions
                .Select(c => c.Searchable)
                .SingleOrDefault();

  bool editable = conditions
                    .Select(c => c.Editable)
                    .SingleOrDefault();

Using reflection is overkill. Assuming you are checking to see if there are ANY conditions in the list that match Editable or Searchable , you should maybe just use the Any() syntax...

You could use a method such as

public bool CheckCondition(IEnumerable<Condition> conditions, Func<Condition, bool> predicate)
{
    return conditions.Any(predicate);
}

and use it like:

var isSet = CheckCondition(conditions, c => c.Editable);

But you aren't saving yourself much. You might as well just write the Any() every time. For example,

var isEditable = conditions.Any(c => c.Editable);
