如何使用强类型字典 <string,Type> 将字符串与类关联

Question

I want to create a dictionary to associate a string to a class for example:

"dog" -> Dog class
"cat" -> Cat class

so I tried this

public Dictionary<String, Type> dic = new Dictionary<String, Type>();
dic.Add("dog", Dog);

but Add doesn't accept Dog .

So what's the syntax ?

Answer 1

You should use the typeof operator to get the corresponding Type object:

public Dictionary<String, Type> dic = new Dictionary<String, Type>();
dic.Add("dog", typeof(Dog));

Answer 2

In .Net there is a dedicated class, System.Type , used to describe classes/structures/enums (any type) in the system. Dog is the class you want this info about, to get it you can either retrieve it using just the Type by using typeof(Dog) , or--if you have an instance of Dog you can use myDog.GetType();

Answer 3

public Dictionary<String, Type> dic = new Dictionary<String, Type>();
dic.Add("dog", typeOf(Dog));

Answer 4

typeof（Dog）如果Dog是一个对象
