问题描述
我在 .Net 4.5 中使用 Json.Net,当在以下对象上使用填充对象时,它会使用 json 的内容来增加 List 的值,而不是设置它的值.
I am using Json.Net for .Net 4.5 and when using populate object on the following object it increments the List's with the content of the json rather than setting its value.
Json.Net
JsonConvert.PopulateObject(string, object)
类
class MySettingSubClass
{
public List<string> MyStringList1 = new List<string>(){"one", "two", "three"}
}
class MySetting
{
public string MyString = "MyString";
public int MyInt = 5;
public MySettingSubClass MyClassObject = new MySettingSubClass();
public List<string> MyStringList2 = new List<string>{"one", "two", "three"};
}
当它们最初加载时,一切都是正确的,但是从 JSON 重新加载两个 MyStringLists 都是重复的 one"、two"、three"、one"、two"、three"
When they initially load, all is correct, however reloading from JSON both MyStringLists are duplicated "one", "two", "three", "one", "two", "three"
推荐答案
你应该告诉 Json.Net 替换数组,像这样:
You should tell Json.Net to replace the arrays, like this:
var serializerSettings = new JsonSerializerSettings {ObjectCreationHandling = ObjectCreationHandling.Replace};
JsonConvert.PopulateObject(jasonString, myObject, serializerSettings)
