针对多个索引值的PropertyChanged

Question

To raise a PropertyChanged event for an indexer and a particular index value, do this:

OnPropertyChanged(string.Format(CultureInfo.CurrentCulture, "Item[{0}]", indexValue));

But what if the indexer accepts multiple index values? Rather than Item[{0}] , what should the format string look like? Is it Item[{0},{1},{3}] or perhaps Item[{0}][{1}][{3}] ?

Answer 1

I've had something similar where I passed in multiple values to a function that was subscribed to OnPropertyChanged and just used some char to parse the items.

If I understand correctly you're just trying to get those values correct?

You could do:

 OnPropertyChanged(string.Format(CultureInfo.CurrentCulture, "Item[{0}];Item[{1}];Item[{2}]", indexValue, indexValue1, indexValue2));

Then just parse on ; using:

string[] stringArray = yourString.Split(';')

Hope that helps
