c#中参数的动态类型转换

public class MyClass
{
    public int MyIntProperty { get; set; }
    public string MyStringProperty { get; set; }
}

public void MyMethod(dynamic obj)
{
    if (obj is MyClass)
    {
        MyClass myClass = (MyClass)obj;
        Console.WriteLine("MyIntProperty: " + myClass.MyIntProperty);
        Console.WriteLine("MyStringProperty: " + myClass.MyStringProperty);
    }
    else if (obj is int)
    {
        int myInt = (int)obj;
        Console.WriteLine("My int value: " + myInt);
    }
    else if (obj is string)
    {
        string myString = (string)obj;
        Console.WriteLine("My string value: " + myString);
    }
}
