internal interface Rule {
}
private class Rule<T> : Rule {
//Properties & Other Stuff
}
void method() {
//For simplicity I used string here. It can be anything when the code is in context
Type _type = typeof(string);
Rule[] _rules;
//This is causing an error because _type could not be found
_rules = new Rule<_type>[] { };
}
是否有可能使用存儲在變量中的泛型類型實例化一個類?初始化泛型類作爲變量
- 編輯
從我的第一個例子,我想我能夠運用相同的概念調用方法。但似乎我錯了。我試圖使用newtonsoft json庫將字符串反序列化爲泛型類型。我發現這個question,它允許你調用一個泛型類型的方法。我環顧四周如何將對象轉換爲_foo,但只能找到類型已知的地方。任何想法?
Using Newtonsoft.Json;
void method() {
//For simplicity I used string here. It can be anything when the code is in context
Type _type = typeof(string);
Rule[] _rules;
// ------------------ New Additions ----------------
var _foo = (Rule[])Array.CreateInstance(typeof(Rule<>).MakeGenericType(_type),0);
MethodInfo method = typeof(JsonConvert).GetMethod("DeserializeObject");
MethodInfo generic = method.MakeGenericMethod(_foo.GetType());
//How do you cast this to a type _myType?
_rules = generic.Invoke(this, new[] { "JSON Data" });
}
