I cannot seem to find a way to have LINQ return the value from a specified accessor.
I know the name of the accessors for each object, but am unsure if it is possible to pass the requested accessor as a variable or otherwise achieve the desired refactoring.
Consider the following code snippet:
// "value" is some object with accessors like: format, channels, language
row = new List<String> {
String.Join(innerSeparator, (from item in myObject.Audio
orderby item.Key ascending
select item.Value.format).ToArray()),
String.Join(innerSeparator, (from item in myObject.Audio
orderby item.Key ascending
select item.Value.channels).ToArray()),
String.Join(innerSeparator, (from item in myObject.Audio
orderby item.Key ascending
select item.Value.language).ToArray()),
// ...
}
I'd like to refactor this into a method that uses the specified accessor, or perhaps pass a delegate, though I don't see how that could work.
string niceRefactor(myObj myObject, string /* or whatever type */ ____ACCESSOR) {
return String.Join(innerSeparator, (from item in myObject.Audio
orderby item.Key ascending
select item.Value.____ACCESSOR).ToArray());
}
I have written a decent amount of C#, but am still new to the magic of LINQ. Is this the right approach? How would you refactor this?
