我可以序列C＃类型的对象？ [英] Can I serialize a C# Type object?

问题描述

我想序列化以下列方式Type对象：

I'm trying to serialize a Type object in the following way:

Type myType = typeof (StringBuilder);
var serializer = new XmlSerializer(typeof(Type));
TextWriter writer = new StringWriter();
serializer.Serialize(writer, myType);

当我这样做，以序列化调用抛出以下异常：

When I do this, the call to Serialize throws the following exception:

是没有预料到的类型System.Text.StringBuilder。使用
XmlInclude或SoapInclude属性来指定不属于
静态已知类型。

"The type System.Text.StringBuilder was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically."

有我的方式来序列化键入对象吗？请注意，我不是要序列化的StringBuilder 本身，而是键入包含有关的元数据对象的StringBuilder 类。

Is there a way for me to serialize the Type object? Note that I am not trying to serialize the StringBuilder itself, but the Type object containing the metadata about the StringBuilder class.

推荐答案

我不知道，一个Type对象可以创建仅包含完全限定名称的字符串。要获得完全合格的名称，可以使用以下内容：

I wasn't aware that a Type object could be created with only a string containing the fully-qualified name. To get the fully qualified name, you can use the following:

string typeName = typeof (StringBuilder).FullName;

您可以再坚持这个字符串但是必须的，那么重建这样的类型：

You can then persist this string however needed, then reconstruct the type like this:

Type t = Type.GetType(typeName);

如果您需要创建类型的实例，你可以这样做：

If you need to create an instance of the type, you can do this:

object o = Activator.CreateInstance(t);

如果您检查o.GetType（）的值，这将是StringBuilder的，就像你期望。

If you check the value of o.GetType(), it will be StringBuilder, just as you would expect.
