我是Web API的新手，我正试图将其集成到我正在研究的项目中。
我将一个复杂的类型发送给WebApi操作，但是当我这样做时，它调用我的类型构造函数，这最终会覆盖我发送给该方法的值。
这正常吗?我在fiddler中看到了实际值，我想在反序列化对象时保留这些值。我应该用别的方法来实现这个目标吗?任何帮助或知识将非常感激!谢谢!:)

就像我提到的，我的fiddler显示正确的值，但它似乎调用我的构造函数，它使用我的初始化值，而不是在Web API方法。
可能是我的班级太大了吗?当我使用较小的类时，它似乎有效。
这是正常的。当你将一个复杂类型传递给web api时，这个对象实际上被api控制器作为字符串读取，并被序列化成由签名确定的正确对象。但是要做到这一点，需要调用类的基构造函数，因此在您的示例中，调用无参数构造函数，然后控制器尝试填充在对象的sting表示中传递的属性。基本上要解决这个问题，你需要有一个基本的无参数构造函数，它没有初始化值
