将ObservableCollection <myclass>复制到ObservableCollection <keyvaluepair <string，object>＆gt;

Question

我想知道是否有人可以告诉我更简单的方法将ObservableCollection<myclass>复制到ObservableCollection<KeyValuePair<string, object>>

这就是我的表现：

 KeyValueCollection=new ObservableCollection<KeyValuePair<string, object>>();

 //Collection = ObservableCollection<myclass>
 foreach (var entry in Collection)
        {
             KeyValueCollection.Add(new KeyValuePair<string, object>(entry.Name,entry));
        }

Answer 1

您可以像这样使用ToDictionary()：

ObservableCollection<KeyValuePair<string, object>> KeyValueCollection =
          new ObservableCollection<KeyValuePair<string, object>>(collection.ToDictionary(
              entry => t.Name, 
              entry => (object)entry));

这会通过选择Dictionary<string,object>的{​​{1}}属性作为将Name转换为myclass作为值来创建myclass。

由于object是Dictionary<string,object>，您可以将其用作IEnumerable<KeyValuePair<string, object>>的构造函数参数。
