我在我的应用程序的code的片段（它引用System.Windows.Forms的的），它试图解决的类型信息的表格像这样的类：

I have a snippet of code in my application (which references System.Windows.Forms) which attempts to resolve type information for a Form class like so:

Type tForm = Type.GetType("System.Windows.Forms.Form");
dynamic instance = Activator.CreateInstance(tForm);

但 Activator.CreateInstance 失败，因为 TForm的为空。

but Activator.CreateInstance fails because tForm is null.

我要如何解决这个问题？

How do I solve this?

编辑：类型必须是可解析在运行时

推荐答案

您需要使用的类型的程序集限定名称

You need to use assembly-qualified name of the type

Type tForm = Type.GetType("System.Windows.Forms.Form, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089");
