C# Returning object from Array leaves pointer to Array item

Question

I have a List<T> and I do the following:

var myObj = List[2];  //Return object at position 2
myObj.Name = "fred";  //If you look at List[2] its name has changed to fred

I tried the following but it still updates the item in the List

var newObj = new MyObj();
var myObj = List[2];  //Return object at position 2
newObj = myObj;
newObj.Name = "fred";  //If you look at List[2] its name has still changed to fred

How can I avoid this pointer remaining so I can update properties without it updating it in the list?

Answer 1

You could make your object implement the ICloneable interface using the MemberwiseClone method and then:

var myObj = List[2];
var newObj = myObj.Clone();
newObj.Name = "fred";

UPDATE:

As pointed out in the comments section it is not recommended to implement the ICloneable interface as it does not specify if it will perform a shallow or deep clone. Just add a Clone method to your class.
