Answer 1

您可以在此处查看如何从对象创建数据集？

有很多方法可以用来从 json 字符串实例化一个对象。

如果您不能使用任何类型的第三方库，例如 Newtonsoft.Json，您可以使用JsonReaderWriterFactory 来完成

public static TEntity Create<TEntity>(string json)
{
    using (var memoryStream = new MemoryStream())
    {
        byte[] jsonBytes = Encoding.UTF8.GetBytes(json);
        memoryStream.Write(jsonBytes, 0, jsonBytes.Length);
        memoryStream.Seek(0, SeekOrigin.Begin);
        using (var jsonReader = JsonReaderWriterFactory.CreateJsonReader(
            memoryStream,
            Encoding.UTF8,
            XmlDictionaryReaderQuotas.Max,
            null))
        {
            var     serializer = new DataContractJsonSerializer(typeof(TEntity));
            TEntity entity     = (TEntity)serializer.ReadObject(jsonReader);
            return entity;
        }
    }
}

反之亦然

public static string Create(object entity)
{
    var serializer = new DataContractJsonSerializer(entity.GetType());

    using (var stream = new MemoryStream())
    {
        using (var writer = JsonReaderWriterFactory.CreateJsonWriter(stream, Encoding.UTF8))
        {
            serializer.WriteObject(writer, entity);
        }

        return Encoding.UTF8.GetString(stream.ToArray());
    }
}

然后，您只需稍微使用 C# 即可使用您的对象实例填充所需的 DataSet。

这是我的代码
