Deserialize JSON text to a specific object type using the Type name [duplicate]

问题

This question already has answers here:

Referencing a type from string name in a type parameter (2 answers)

Closed 2 years ago.

I used to deserialize JSON text to a strongly type object using the code below

Trainer myTrainer = JsonConvert.DeserializeObject<Trainer>(sJsonText);

Now I need to convert deserialize JSON text to a specific type knowing only the name of the type.

I tried to use Reflection to get the Type from its name then use this type with JsonConvert as shown below:

Type myType = Type.GetType("Trainer");
var jobj = JsonConvert.DeserializeObject<myType >(sJsonText);

but unfortunately, the error below shown up:

CS0118  'myType' is a variable but is used like a type

Is there a way that I can make reference to a class using a string?

回答1:

Use JsonConvert.DeserializeObject(string, Type):

var jobj = JsonConvert.DeserializeObject(sJsonText, myType);

Or if you prefer

dynamic jobj = JsonConvert.DeserializeObject(sJsonText, myType);
