c# - 为 foreach 获取 ObjectModel.ReadOnlyCollection

Question

我想获取对象的值和键。首先，我将其转换，然后将其放在foreach循环中以获取键和值。

object itemAttributes = web.javaScriptExecutor().ExecuteScript($"return window.INITIAL_STATE.items.itemAttributes")

                    var items = (ReadOnlyCollection<object>)itemAttributes;


                        foreach (Dictionary<string, object> item in items)
                        {
                            foreach (KeyValuePair<string, object> kvp in item)
                            {
                                if (Convert.ToString(kvp.Value) != null)
                                {
                                     Name = Convert.ToString(kvp.Key), Value = Convert.ToString(kvp.Value) });
                                }
                            }
                        }

我想投射时出现错误

var items = (ReadOnlyCollection<object>)itemAttributes;

//Unable to cast object of type 'System.Collections.Generic.Dictionary`2[System.String,System.Object]' to type 'System.Collections.ObjectModel.ReadOnlyCollection`1[System.Object]'.
