Parsing a JSON array using Json.Net
提问by johngeek
I'm working with Json.Net to parse an array. What I'm trying to do is to pull the name/value pairs out of the array and assign them to specific variables while parsing the JObject.
我正在使用 Json.Net 来解析数组。我想要做的是从数组中提取名称/值对，并在解析 JObject 时将它们分配给特定变量。
Here's what I've got in the array:
这是我在数组中的内容：
[
{
"General": "At this time we do not have any frequent support requests."
},
{
"Support": "For support inquires, please see our support page."
}
]
And here's what I've got in the C#:
这是我在 C# 中得到的：
WebRequest objRequest = HttpWebRequest.Create(dest);
WebResponse objResponse = objRequest.GetResponse();
using (StreamReader reader = new StreamReader(objResponse.GetResponseStream()))
{
string json = reader.ReadToEnd();
JArray a = JArray.Parse(json);
//Here's where I'm stumped
}
I'm fairly new to JSON and Json.Net, so it might be a basic solution for someone else. I basically just need to assign the name/value pairs in a foreach loop so that I can output the data on the front-end. Has anyone done this before?
我对 JSON 和 Json.Net 还很陌生，所以它可能是其他人的基本解决方案。我基本上只需要在 foreach 循环中分配名称/值对，以便我可以在前端输出数据。以前有人这样做过吗？

You can get at the data values like this:
你可以得到这样的数据值：
string json = @"
[
{ ""General"" : ""At this time we do not have any frequent support requests."" },
{ ""Support"" : ""For support inquires, please see our support page."" }
]";
JArray a = JArray.Parse(json);
foreach (JObject o in a.Children<JObject>())
{
foreach (JProperty p in o.Properties())
{
string name = p.Name;
string value = (string)p.Value;
Console.WriteLine(name + " -- " + value);
}
}

Use Manatee.Json https://github.com/gregsdennis/Manatee.Json/wiki/Usage
使用 Manatee.Json https://github.com/gregsdennis/Manatee.Json/wiki/Usage
And you can convert the entire object to a string, filename.json is expected to be located in documents folder.
您可以将整个对象转换为字符串，filename.json 应位于文档文件夹中。
var text = File.ReadAllText("filename.json");
var json = JsonValue.Parse(text);
while (JsonValue.Null != null)
{
Console.WriteLine(json.ToString());
}
Console.ReadLine();
