C# 根据键尾号将json数据分组到列表中

我得到了一个json结果，如图1所示，但我需要一个输出，如图2所示。

我参加了以下课程

public class NameDTO
        {
            public string Name;
        }

        public class ValDTO
        {
            public string Val;
        }

我得到了上述类的列表，如图3和图4所示，并将它们合并并转换为json。

如何进行分组，以便获得正确的输出，如图2所示

谢谢。

如果可能，您可以使用Json.NET。 这里有一个例子来解决你的问题

const string JSON = @"{
    ""message-Code-1"": ""000"",
    ""msg-Number-Pos1-1"": ""0000"",
    ""msg-Number-Pos2-1"": ""1"",
    ""msg-Number-Pos3-1"": ""1"",
    ""message-Code-2"": ""1"",
    ""msg-Number-Pos1-2"": ""0001"",
    ""msg-Number-Pos2-2"": ""2"",
    ""msg-Number-Pos3-2"": ""1"",
    ""message-Code-3"": ""0002"",
    ""msg-Number-Pos1-3"": ""3"",
    ""msg-Number-Pos2-3"": ""1"",
    ""msg-Number-Pos3-3"": ""1"",
    ""message-Code-4"": ""0003"",
    ""msg-Number-Pos1-4"": ""3"",
    ""msg-Number-Pos2-4"": ""1"",
    ""msg-Number-Pos3-4"": ""1""
}";

JObject loMessages = JObject.Parse(JSON);
JArray loMessageArray = new JArray();
JObject loAddMessage;
foreach (var loMessageGroup in loMessages.Properties().GroupBy(item => Regex.Match(item.Name,@".*-(?<pos>\d+)").Groups["pos"].Value))
{
    loAddMessage = new JObject();
    foreach (var loMessage in loMessageGroup)
        loAddMessage[loMessage.Name] = loMessage.Value.ToString();
    loMessageArray.Add(loAddMessage);
}
Console.WriteLine(loMessageArray.ToString());

您显示的代码片段都不是C，因此我将语言标记更改为C#（我假设您正在使用）。请在以后的问题中使用正确的标签。是。。我用的是c#。我错漏了。我会确保的。谢谢。这可能不起作用，因为我必须再次在您的上下文中重新构建我的字符串，即conststringjson。

const string JSON = @"{
    ""message-Code-1"": ""000"",
    ""msg-Number-Pos1-1"": ""0000"",
    ""msg-Number-Pos2-1"": ""1"",
    ""msg-Number-Pos3-1"": ""1"",
    ""message-Code-2"": ""1"",
    ""msg-Number-Pos1-2"": ""0001"",
    ""msg-Number-Pos2-2"": ""2"",
    ""msg-Number-Pos3-2"": ""1"",
    ""message-Code-3"": ""0002"",
    ""msg-Number-Pos1-3"": ""3"",
    ""msg-Number-Pos2-3"": ""1"",
    ""msg-Number-Pos3-3"": ""1"",
    ""message-Code-4"": ""0003"",
    ""msg-Number-Pos1-4"": ""3"",
    ""msg-Number-Pos2-4"": ""1"",
    ""msg-Number-Pos3-4"": ""1""
}";

JObject loMessages = JObject.Parse(JSON);
JArray loMessageArray = new JArray();
JObject loAddMessage;
foreach (var loMessageGroup in loMessages.Properties().GroupBy(item => Regex.Match(item.Name,@".*-(?<pos>\d+)").Groups["pos"].Value))
{
    loAddMessage = new JObject();
    foreach (var loMessage in loMessageGroup)
        loAddMessage[loMessage.Name] = loMessage.Value.ToString();
    loMessageArray.Add(loAddMessage);
}
Console.WriteLine(loMessageArray.ToString());

[
  {
    "message-Code-1": "000",
