如何从 C# Asp.Net 中的 JSON 结果字符串中检索值

Question

如何解析 JSon 下面的字符串以获得 RESULT & ERROR 的值？

{
    "RESPONSE": [
        {
            "DT": "20210317",
            "I_NO": "1031021",
            "C_NO": "1021",
            "RESULT": "E",
            "DCODE": "2-B1",
            "ERROR": "[AMT] is mandatory."
        }
    ]
}

Answer 1

创建 c# class 以进行反序列化。

public class RESPONSE
{
    public string DT { get; set; }
    public string I_NO { get; set; }
    public string C_NO { get; set; }
    public string RESULT { get; set; }
    public string DCODE { get; set; }
    public string ERROR { get; set; }
}

public class Root
{
    public List<RESPONSE> RESPONSE { get; set; }
}

然后用Newtonsoft反序列化

var response = JsonConvert.DeserializeObject<Root>(jsonString);
