我正在使用Json.Net for .Net 4.5,并且在以下对象上使用填充对象时,它会使用json的内容而不是设置其值来增加List的值。
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,一切都正确,但是从JSON重新加载两个MyStringLists都是重复的 "one", "two", "three", "one", "two", "three"
"one", "two", "three", "one", "two", "three"
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)
