我正在使用 JSON.NET 库.我创建了几个 JObject 并将它们添加到 JArray.
I am using JSON.NET library. I have created few JObjects and added them to a JArray.
JArray array = new JArray();
JObject obj = new JObject();
obj.Add(new JProperty("text", "One"));
obj.Add(new JProperty("leaf", false));
array.Add(obj);
obj = new JObject();
obj.Add(new JProperty("text", "Two"));
obj.Add(new JProperty("leaf", false));
array.Add(obj);
obj = new JObject();
obj.Add(new JProperty("text", "Three"));
obj.Add(new JProperty("leaf", true));
array.Add(obj);
现在我想找到一个文本(JProperty)是Two
的JObject.如何使用 JProperty 在 JArray 中找到 JObject.
Now I want to find a JObject who's text (JProperty) is Two
. How can I find a JObject within a JArray by using a JProperty.
你可以这样找到:
JObject jo = array.Children<JObject>()
.FirstOrDefault(o => o["text"] != null && o["text"].ToString() == "Two");
这将在 JArray
中找到第一个 JObject
,它的属性名为 text
,其值为 Two
.如果不存在这样的 JObject
,则 jo
将为空.
This will find the first JObject
in the JArray
having a property named text
with a value of Two
. If no such JObject
exists, then jo
will be null.
