如何得到

在c#中解析JSON

我刚用了Newtonsoft。Json，并能够读取Json与以下代码:

string json = File.ReadAllText(pathToFile);
dynamic jsonObj = JsonConvert.DeserializeObject(json);
dynamic value = jsonObj["Value"];
foreach (var val in value)
{
     Console.WriteLine(val.Name);
}

您将需要包括Microsoft。

如前所述，如果您没有合法的JSON，那么您需要编写自己的解析器。

这并不难做到，但是您没有提供源文件的充分定义，我无法为您编写它。例如，您是否真的发布了正确的JSON?它总是从"value"开始吗，其他物质有多少是固定的或可以变化的?

如果您想使用自定义解析，另一种解决方案是:

var source = File.ReadAllText(pathToFile);
string pattern = @"""'d{10}""";    // Note: {10} wil match only 10 digit number           
var matches = Regex.Matches(source, pattern);
foreach (var val in matches)
   Console.WriteLine(val);
