使用反射投射到通用类型化对象(Casting to a Generic Typed Object Using Reflection)

如果我直到运行时才知道T是什么，才可以使用反射将对象从类型object为MyType<T> ？

Can I cast an object from type object to MyType<T> using reflection if I don't know what T is until runtime?

您不能在编译时转换为未知类型。 铸造实际上仅作为编译时构造有用，因为您需要知道该类型才能直接使用它。

如果你的目标是通过反射来处理对象，那么这是一个不同的场景。 在这种情况下，您可以使用Type.MakeGenericType为您的对象创建正确的类型。

这将允许您使用反射来处理您的对象。

You can't cast to a type unknown at compile time. Casting is really only useful as a compile-time construct, as you'd need to know the type in order to use it directly.

If your goal is to work with the object via Reflection, however, that's a different scenario. In that case, you can use Type.MakeGenericType to create the correct type for your object.

This will allow you to use reflection to work upon your object.
