将对象强制转换为以Type对象表示的类 [英] Cast an object to a class represented as Type object

问题描述

好吧，我什至不知道标题是否有意义，但是我很难描述我需要做什么。因此，请看示例plz。

Ok i dont even know if the title makes any sense, but i am having difficulty describing what i need to do. So take a look at the example plz.

我正在这样做：

(SportsParent)JsonConvert.DeserializeObject<SportsParent>(jsonObj);

但是如果我想将类名 SportsParent存储在字符串中并创建一个从中键入对象。然后使用该Type对象进行投射。

But what if i wanted to have the class name "SportsParent" stored in a string, and create a Type object from it. And then use that Type object for casting.

类似这样的东西：

Type type = Type.GetType("myNanespace.SportsParent");
(type )JsonConvert.DeserializeObject<type >(jsonObj);

谢谢。

推荐答案

JsonConvert.DeserializeObject 的重载可以接受 Type 。试试这个：

There is an overload of JsonConvert.DeserializeObject that accepts a Type. Try this:

string typeName = "myNamespace.SportsParent";

Type type = Type.GetType(typeName);
object obj = JsonConvert.DeserializeObject(jsonObj, type);

然后，在您的代码后面...

Then, later in your code...

if (obj is SportsParent)
{
    SportsParent sp = (SportsParent) obj;
    // do something with sp here
}
else if (obj is SomeOtherType)
{
    SomeOtherType sot = (SomeOtherType) obj;
    // handle other type
}
else
{
    throw new Exception("Unexpected type: " + obj.GetType().FullName);
}
