反序列化 response.Result.Content.ReadAsStreamAsync() 时出现 memory 异常以获取超过 400 mb 的响应

Question

如何反序列化为 2GB 左右的 object。

将 100000 条记录添加到 List 后退出 memory 异常。

请让我知道是否有替代方法可以在列表 object 或字符串中返回大约 900000 条记录？

var repsonse = httpClient.PostAsync(url,content);
List<object> lstObj = new List<object>();

using (var responseStream = response.Result.Content.ReadAsStreamAsync().Result)
{
    using (var textReader = new StreamReader(responseStream))
    {
        using (var jsonReader = new JsonTextReader(textReader))
        {
            while (jsonReader.Read())
            {
                object o = serializer.Deserialize<object>(jsonReader);
                lstObj.Add(o);
            }
        }
    }
}

if you realy need to load 2gb of an object in memory, Go to the project properties, you need to select Target platform "AnyCpu", so you can run on 64bits and use the memory enter image description here
