List<>.Exists() doesn't exist in WP7?

Question

Unless I'm missing something here Exists() doesn't exist in WP7? If this is true does someone know of an equivalent?

Answer 1

By looking at the MSDN it seems it doesn't exist. You can simulate it with:

 myList.Any(p => p == something);

Answer 2

.Any（）.Contains（）应该正常工作
