C# 我反序列化哪里出了问题

我正在尝试获取有关stackoverflow的问题总数，因为我正在做一个练习，并且一直在进行反序列化

如果有人能让我知道我需要做什么，我将不胜感激，也许能提供一些示例代码来帮助我

当我在控制台中运行这个时，我得到了错误 “反序列化类型的对象时出错。遇到意外字符”，该字符是向下指向的三角形

这就是我目前所拥有的

它返回的是压缩内容（特别是gzip）。如果可能，请告诉您的http客户端自动解压缩：

request.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip,deflate");
request.AutomaticDecompression =
    DecompressionMethods.GZip | DecompressionMethods.Deflate;

下一个问题是：模式不匹配；问题在根目录的

项中：

[DataContract]
public class Response
{
    [DataMember(Name ="items")]
    List<Question> questions { get;set; }
}

[DataContract]
公众课堂反应
{
[DataMember（Name=“items”）]
列出问题{get；set；}
}
您是否考虑过简单地使用StacMan或其他现有库？我不知道SO api，也从未遇到过“向下三角形…”，但我建议您使用NewtonSoft.Json库进行Json反序列化。此url的响应与响应类的属性不匹配。您建议这样做的原因是什么？我对这类请求的经验非常有限。@SimonPrice紧接着
GetResponse（）
@SimonPrice之前，在这种情况下，我强烈建议使用类似stacman的工具来更改[DataContract]公共类响应{[DataMember（Name=“items”）]列表问题{get；set；}这会引发类型或命名空间名称列表无法找到的错误found@SimonPrice如果您愿意，请使用

List
只需要在表单顶部使用

使用System.Collections.Generic
