Question

我想创建一个函数，它可以使用两个参数object和type，然后使用type参数将对象类型转换为适当的类型。那可能吗？我怎么能实现它？

public class TEST
{
    public int test;
}
object ot = new TEST();
Type type = typeof(TEST);
TEST t = (type)ot;

//Function will be something like this Type t is type we get using typeof() 
public string SearializeObject(Object obj, Type t)
{
    //check if obj is of type t
    if(obj is of type t){
    //cast obj to type t to read it
    ((Type t)obj).someMethod
}
}

Answer 1

public T cast<T>(object obj)
{
   return (T)obj;
}

object ot = new TEST();
TEST t = cast<TEST>(ot);

Answer 2

我会使用Generic方法：

public string SerializeObject<T>(object obj)
{
  if(obj is T)
    (obj as T).someMethod();
}

帮我解决类型问题
