[英]Cast an object to a class represented as Type object
Ok i dont even know if the title makes any sense, but i am having difficulty describing what i need to do. 好的,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。 So take a look at the example plz.
因此,请看示例plz。
I am doing this: 我正在这样做:
(SportsParent)JsonConvert.DeserializeObject<SportsParent>(jsonObj);
But what if i wanted to have the class name "SportsParent" stored in a string, and create a Type object from it. 但是,如果我想将类名称“ SportsParent”存储在字符串中,并从中创建Type对象,该怎么办? And then use that Type object for casting.
然后使用该Type对象进行投射。
Something like that: 像这样:
Type type = Type.GetType("myNanespace.SportsParent");
(type )JsonConvert.DeserializeObject<type >(jsonObj);
Thank you. 谢谢。
There is an overload of JsonConvert.DeserializeObject
that accepts a Type
. JsonConvert.DeserializeObject
有一个接受Type
的重载。 Try this: 尝试这个:
string typeName = "myNamespace.SportsParent";
Type type = Type.GetType(typeName);
object obj = JsonConvert.DeserializeObject(jsonObj, type);
Then, later in your code... 然后,稍后在您的代码中...
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);
}
