在一些情况下，我们并不清楚匿名对象具备哪些属性，当需要合并两个匿名对象时，手动实现比较复杂，可以直接使用TypeMerger来实现merge

TypeMerger简单使用

TypeMerger是 .NET Core中的对象合并方法，支持多种合并处理方式，这里只简单的使用一下。

使用包管理进行安装：

TypeMerger

示例代码：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
var config1 = new {
    name = "Tom",
    age = 18
};

var config2 = new {
    age = 20,
    desc = "A student in high school",
    experience = new
    {
       first = "Grade 6 of primary school won the third prize in football",
       second = "I was the first in my class in the final exam of the third year of junior high school"
    }
}
var mergeConfig = TypeMerger.TypeMerger.Merge(config1, config2);
var configString = JsonConvert.SerializeObject(mergeConfig);
Console.WriteLine(configString);

返回结果：

1
2
3
4
5
6
7
8
9
{
  "name": "Tom",
  "age": 18,
  "desc": "A student in high school",
  "experience": {
    "first": "Grade 6 of primary school won the third prize in football",
    "second": "I was the first in my class in the final exam of the third year of junior high school"
  }
}

直接merge两个对象（JObject或者匿名对象），如果两个对象有相同属性，默认情况下，第二个对象的属性值会被忽略。

如果想要第二个对象的age，代码微调：

1
2
3
var mergeConfig = TypeMerger.TypeMerger.Ignore(() => config1.age).Merge(config1, config2);
var configString = JsonConvert.SerializeObject(mergeConfig);
Console.WriteLine(configString);

或者调整object的顺序即可。
