csharp实现两个对象的合并
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：
示例代码：
csharp
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：
json
{
"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：
csharp
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。
