我有一个这样的 JSON 字符串:
I have a JSON string like this:
{
"code": "GENDER",
"value": { "option": "ML" }
}
如果值为 "ML"
和 "Female",我想将
option
属性更新为 "Male"
如果值为 "FM"
.
I would like to update the option
property to "Male"
if the value is "ML"
and "Female"
if the value is "FM"
.
我已经到了这一点,但不确定如何继续:
I have got to this point, but am unsure how to proceed:
JArray contentobject = (JArray)JsonConvert.DeserializeObject(contentJSON);
JObject voicgObj = contentobject.Children().FirstOrDefault(ce => ce["code"].ToString() == "GENDER") as JObject;
JProperty voicgProp = voicgObj.Property("value");
我不知道如何访问 option
,它是 value
的子项.
I don't know how to get to the option
which is a child of value
.
提前致谢.任何指针都会很棒.
Thanks in advance. Any pointers would be great.
可以通过属性作为键来访问对象:
You can access the object by using properties as keys:
JObject obj = JObject.Parse(json);
string gender = (string)obj["value"]["option"];
对于您的示例,请尝试:
For your example, try:
JObject obj = JObject.Parse(json);
var val = obj["value"];
string option = (string)val["option"];
if (option == "ML")
val["option"] = "Male";
if (option == "FM")
val["option"] = "Female";
string result = obj.ToString();
