Converting observable collection back to regular collection
提问by Shawn Mclean
A function has a parameter of type object. I debugged it to see what type of datatype the other part of the program sent me. The base was of an ObservableCollection. How do i convert that to a list?
一个函数有一个对象类型的参数。我调试它以查看程序的另一部分发送给我的数据类型类型。基础是 ObservableCollection。我如何将其转换为列表？

Depending on the type of object in the ObservableCollection... I'll assume it's an intfor this example:
根据ObservableCollection......中对象的类型，我假设它是int这个例子的一个：
IEnumerable<int> obsCollection = (IEnumerable<int>)GetCollection();
var list = new List<int>(obsCollection);

ObservableCollectionimplements IList<T>, so you should be able to use ToList()on it.
ObservableCollection实现IList<T>，所以你应该可以使用ToList()它。

The Items property returns an IList. See http://msdn.microsoft.com/en-us/library/ms132435.aspx
Items 属性返回一个 IList。 请参阅 http://msdn.microsoft.com/en-us/library/ms132435.aspx

Given that ObservableCollection<T>implements IEnumerable<T>you can give it to the constructor of List<T>:
鉴于ObservableCollection<T>实现，IEnumerable<T>您可以将其提供给以下的构造函数List<T>：
List<T> myList = new List<T>(myObservableCollection);
Where Tis the type of the items in the collection.
T集合中项目的类型在哪里。

Just need to add the namespace using System.Linq;
只需要添加命名空间 using System.Linq;
and use the method ToList()in the ObservableCollection object
并使用ToList()ObservableCollection 对象中的方法
回答by Ion Todirel
I think the issue here is that ObservableCollection might be modified on the fly when you try to convert it to a List or use as such, so you might need to use a watchdog timer of sorts until ObservableCollection finishes
我认为这里的问题是当您尝试将 ObservableCollection 转换为 List 或将其用作此类时，可能会动态修改 ObservableCollection，因此您可能需要使用各种看门狗计时器，直到 ObservableCollection 完成
