indexof自定义列表的功能

Question

I need to update an entry in a custom list which i created, the list is shown below:
List<Data> Test = new List<Data>();
I found some solutions proposed online such as using FindIndex , however this function is not present.
Note: I'm using C# in windows phone 7 development if this helps.
Thanks

Answer 1

If you don't want to find the object by an index, but by some field inside your class, you could do something like this. I'm assuming your DATA object has a unique ID field inside it...

var someName = "name_i_want_to_find";
var myItems = Test.FindAll(x => x.Name == someName);

foreach (var item in myItems)
    item.FieldToChange = "someNewValue";

Answer 2

List有一个IndexOf方法，它存在于Windows Phone 7版本中。

Use IndexOf() method directly. MSDN
