假设我有两个变量，它们都是 var json = '[{"Status":"Success","Data":[{"UserID":null,"UserName":null,"EmailID":null,"EmailIDExists":false,"Active":null,"Country":null,"WishListID":"31","WishListName":"General","WishListItems":[{"WishListItemID":"3","ItemCode":"4414082000005","ItemName":"Notebook 4414-082","Image":"http://aljeel.gct.om/ProductsImages/4414082000005_MT1.jpg","ItemPrice":0.500,"CreatedDate":"25/05/2018"}]},{"UserID":null,"UserName":null,"EmailID":null,"EmailIDExists":false,"Active":null,"Country":null,"WishListID":"24","WishListName":"Default","WishListItems":[]}],"Message":null}]';
var obj = JSON.parse(json)[0].Data;
obj.data = obj.WishListItems;
delete obj.WishListItems;
json = JSON.stringify([obj]);
console.log("FINAL JSON " + (json));类型。
Dictionary<int, int>两个词典都可能包含相同的键。
我希望它们合并为一个Dictionary<int, int> d1 = new Dictionary<int, int> { ... };
Dictionary<int, int> d2 = new Dictionary<int, int> { ... };
。
这样做的优雅方式是什么？
我尝试过以下方法：
Dictionary<int, int> combinedDictionary但遗憾的是，在尝试返回此组合变量时，我收到以下错误：
无法转换表达式类型＆＃39; System.Collections.Generic.IEnumerable＆gt;＆＃39;返回类型＆＃39; System.Collections.Generic.Dictionary＆＃39;。
是否可以像这样安全地施放它？
var combinedDictionary = d1.Concat(d2.Where(x => !d1.Keys.Contains(x.Key)));
提前感谢！

Concat返回context.FindAllAsync<MyEntity>(1, 2, "foo")。您想调用ToDictionary将其转换为字典。
IEnumerable<KeyValuePair<TKey, TValue>>
