C# 如何解析System.RuntimeType由于其保护级别而无法访问。只能处理公共类型。？

我正在尝试序列化我的类。但我有以下例外

  System.InvalidOperationException was unhandled
  HResult=-2146233079
  Message=There was an error generating the XML document.

       InnerException: 

我的序列化代码是

XmlTextWriter xw = new XmlTextWriter("CustomClassSchema.xml", System.Text.Encoding.UTF8);
xw.Formatting = Formatting.Indented;
XmlSerializer serializer = new XmlSerializer(typeof(CustomSerializer));
CustomSerializer customSerializer = new CustomSerializer()
serializer.Serialize(xw, customSerializer);

请帮我解决这个问题。我需要对自定义类或任何自定义类进行自定义吗？

如果您无法为

CustomSerializer

类提供定义（从名称判断，尝试序列化是件奇怪的事情…），那么您看到此错误的原因是因为类包含一个公共属性，该属性要么是

RuntimeType

，要么继承自

RuntimeType

，要么包含

RuntimeType

属性本身。或者您的整个类继承了

RuntimeType

在任何情况下，

RuntimeType

似乎都是不可序列化的，因此您会看到异常

同样，由于不知道您的

CustomSerializer

是什么，我无法指出确切的解决方案-这可能很简单，就像使属性不可序列化一样…

我们需要查看您的

CustomSerializer

类定义。本质上，该类的某些部分是不可序列化的。而且，看起来你想。。。序列化序列化程序？这看起来有点奇怪，至少可以这么说。谢谢。但是我的自定义类是很大的代码部分。你能告诉我这些问题的根本原因吗？谢谢。我已将属性声明为类型。现在我通过包含[XmlIgnore]属性解决了这个问题
