所以我使用JSON.net进行基于研究的项目。我的示例JSON文件看起来像这样。文件很大但是请耐心等待，我只需要处理它的一部分：

}

所以我只想将name打印到输出窗口，这样我就创建了简单的CName类。这是我的代码：

public class CName
{
     public string name { get; set; }
}

DirectoryInfo dinfo = new DirectoryInfo(@"C:\output_v_2\");
FileInfo[] Files = dinfo.GetFiles("*.json");

foreach (FileInfo file in Files)
{
    CName read_data = JsonConvert.DeserializeObject<CName>(File.ReadAllText(file.Name));
    Debug.WriteLine(read_data.name);
}

编辑：似乎我对JSON的理解真的很差。我想要做的是：从"name" : "ECDHE_RSA_WITH_RC4_128_SHA",和所有与"name"相似的行，我需要那些我无法获得的ECDHE_RSA_WITH_RC4_128_SHA类型值。 但是我得到的只是空白输出。 建议？

感谢。

答案 0 :(得分：0)

如果您只想要一小部分内容并且不想创建完整模型，则可以使用DeserializeObject()代替DeserializeObject<T>()，这将返回一个JToken，这是一个具有所需函数的对象，以迭代它，访问它的成员，如数组等。

Here是JToken文档的链接。
