我试图发送 http 请求,但在PostAsync()行上遇到异常
System.NotSupportedException:不支持“System.Action”实例的序列化和反序列化。路径:$.MoveNextAction。
因此,在不知道结构的情况下,data我只能假设以下内容。Action您有一个类,其中有 的定义。像下面这样的东西。
public class YourData
{
public string Name { get; set; }
public Action TheAction { get; set; }
}

当您尝试序列化它时,您会收到异常。如果这就是您遇到的情况,您将需要更新表示数据的类并向其添加属性,这将排除您不想要/无法序列化的属性。像下面这样的东西
[JsonObject(MemberSerialization.OptIn)]
public class ClassWithAction
{
[JsonProperty]
public string Name { get; set; }
public Action TheAction { get; set; }
}
