c# - 在 WPF 中向 ObservableCollection 添加数据

Question

我这里有一些问题。这里是:我有这门课

public class NewsFeedResources
{
    public string Name { get; set; }
    public string Id { get; set; }
    public string Message { get; set; }

    public static ObservableCollection<NewsFeedResources> _newsfeed = new ObservableCollection<NewsFeedResources>
    {

        new NewsFeedResources { Name = "Joe", Id = "1", Message="Foo" },
        new NewsFeedResources { Name = "Wandy", Id = "2", Message="Bar" },
        new NewsFeedResources { Name = "Yuliana", Id = "3", Message="Baz" },
        new NewsFeedResources { Name = "Hardi", Id = "4", Message="Baz" },

    };

    public static ObservableCollection<NewsFeedResources> newsFeedResources
    { get { return _newsfeed; }

    }
}

如果我有其他数据如

Name=John, Id=5, Message="堆栈溢出"
Name=Jane, Id=6, Message="Hello world"

如何将数据添加到类中，而不是从构造函数中添加？感谢您的帮助

ObservableCollection公开了 Collection<T>.Add 方法:

Adds an object to the end of the Collection.

所以你会:

_newsfeed.Add(new NewsFeedResources {Name = "John",
                                     Id = 5,
                                     Message = "Stack overflow"});
_newsfeed.Add(new NewsFeedResources {Name = "Jane",
                                     Id = 6,
                                     Message = "Hello world"});
