Json.Net PopulateObject追加列表而不是设置值

Question

我将Json.Net用于.Net 4.5，当在以下对象上使用populate对象时，它会用Json的内容来增加List，而不是设置其值。

Json.Net

JsonConvert.PopulateObject(string, object)

类别

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重新加载时，两个MyStringLists都是重复的"one", "two", "three", "one", "two", "three"

Answer 1

您应该告诉Json.Net替换数组，如下所示：

var serializerSettings = new JsonSerializerSettings {ObjectCreationHandling = ObjectCreationHandling.Replace};

JsonConvert.PopulateObject(jasonString, myObject, serializerSettings)
