如何通過C＃中的參數獲取屬性的對象實例？

如何通過C＃中的參數獲取屬性的對象實例？我不知道這是否就是所謂的變量實例，但這裏是我的意思是：如何通過C＃中的參數獲取屬性的對象實例？

在通常情況下，我們這樣做的時候，我們得到的變量在C＃中值：

void performOperation(ref Object property) { 
    //here, property is a reference of whatever was passed into the variable 
} 

Pet myPet = Pet(); 
myPet.name = "Kitty"; 
performOperation(myPet.name); //Here, what performOperation() will get is a string

什麼我希望達到的目標，是從階級的財產，就好說了獲取對象：

void performOperation(ref Object property) { 
    //so, what I hope to achieve is something like this: 

    //Ideally, I can get the Pet object instance from the property (myPet.name) that was passed in from the driver class 
    (property.instance().GetType()) petObject = (property.instnace().GetType())property.instance(); 

    //The usual case where property is whatever that was passed in. This case, since myPet.name is a string, this should be casted as a string 
    (property.GetType()) petName = property; 
} 

Pet myPet = Pet(); 
myPet.name = "Kitty"; 
performOperation(myPet.name); //In this case, performOperation() should be able to know myPet from the property that was passed in

的instance()只是爲了證明，我想要得到的屬性的實例對象的虛擬方法。我對C＃很陌生。這在概念上是我希望達到的目標，但我不確定我在C＃中如何做到這一點。我翻看了Reflection API，但我仍然不確定我應該用什麼來做到這一點。
