我会尝试解释这个问题：
1-从服务器端，我得到了一个名为Document的类，它从类Node扩展（几个类从Node扩展）。
2-从rest API，我得到了一个服务，它发送作为响应Node对象（Document或其他从Node扩展的内容）。休息输出真的是发送所有信息（文档等...）。
3-当到达休息客户端时，我得到Node类（没问题，直到这里一切顺利）。
if (node.GetType() == typeof(Document))
{
// never goes into
var doc = (Document)node;
}
if (node is Document)
{
// never goes into
var doc = (Document)node;
}
4-当我查找Node是Document的类型时，问题就出现了，答案总是错误的。
在有人回答我之前是不可能的（我对java和php完全一样没有问题）。我没有找到密钥（在java中，例如那里有一些注释对它有帮助@XmlSeeAlso（{Document.class，Folder.class，Record.class，Mail.class}））。
我不知道是否可以使用restcharp执行此操作，或者我必须继续执行更低级别的实现。任何线索或帮助都表示赞赏。
