使用JContainer.Merge().

将JSON对象组合在一起的逻辑非常简单:名称/值被复制，如果现有属性已经具有值，则跳过null.

The logic for combining JSON objects together is fairly simple: name/values are copied across, skipping nulls if the existing property already has a value.

示例:

var jObject1 = // Your first json object as JObject
var jObject2 = // Your second json object as JObject 

jObject1.Merge(jObject2);

// jObject1 contains now the merged properties from jObject2.

请注意，对于两个对象中都存在的属性，jObject2优先(即覆盖jObject1中的属性).

Note that for properties that exist in both objects, the jObject2 ones take precedence (i.e. overwrite the properties in jObject1).
