ArrayList Intent. How to write in C#

Question

How to write this in C#?

Intent intent = new Intent(Intent.ActionSendMultiple, Android.Provider.MediaStore.Images.Media.ExternalContentUri);
handler(intent);

....

void handler(Intent intent)
{
    ArrayList<Uri> imageUris = intent.GetParcelableArrayListExtra(Intent.ExtraStream);

    ...
}

`ArrayList` is still avaiable in C# but it belongs on old days when C# doesn't have _generics_. Use `List` instead. — Soner Gönül, Sep 11 '13 at 08:51
It returns IList, read documentation http://docs.go-mono.com/index.aspx?link=M%3AAndroid.Content.Intent.GetIntegerArrayListExtra(System.String) — Ilya Ivanov, Sep 11 '13 at 08:51
I'm sure you're not actually going to ask questions as you progress line by line. Short answer: Use the `List` class (which is not an interface in the C# BCL as opposed to Java's). Long answer: please read the rules of this site... Better answer: I'm sure there exist Java 2 C# translators which work empirically of course, but they could give you a hand.

I edited my question, I want it to match the Intent for Android. But the code is written in Java, so now I want to change it to C# — Calvin89, Sep 11 '13 at 09:01

ArrayList is available is c# but it does not have a generic (<T>) form. ArrayList is a list of objects.

What you want is System.Collections.Generic.List<T>

EDIT : In response to comments, try this;

List<Uri> imageUris = new List<Uri>(intent.GetIntegerArrayListExtra(Intent.ExtraStream));

more pragmatic comment, why not to use `IList`? – Ilya Ivanov Sep 11 '13 at 08:57
Good question. I always shoot for List as it has more methods on it. – Gusdor Sep 11 '13 at 09:00
sorry, It should be intent.GetParcelableArrayListExtra, but when i follow your method, i get error. – Calvin89 Sep 11 '13 at 09:03
`it has more methods on it` just because it is a specific implementation, not the abstraction. Following the principle of dependency inversion, one should rely on concrete implementation. – Ilya Ivanov Sep 11 '13 at 09:12

Easy, just use List<Uri>. It's also faster than ArrayList.
