How to create a new object using string's content as an object name

Question

I am trying to name a Person object with "objectName" as below but not succeeding, any help? How to do it?

string objectNameString = "objectName";
Person objectNameString = new Person();

I try to create a Person list from several user inputs, the names must be unique in list.

Why you don't use `objectName` from the start? I don't see any logic on this. — Christos, Jul 09 '14 at 15:34
What is your goal? Do you want to set the name of the Person, or do you want to set the name of the variable (of Person)? — RvdK, Jul 09 '14 at 15:35

You might be trying to assign a property in Person object instead? — rageit, Jul 09 '14 at 15:36
You need to understand that a *variable* name isn't part of the *object*. Perhaps you just want a `Dictionary`? — Jon Skeet, Jul 09 '14 at 15:37

Following should create new instance of Person using string from objectNameString.

string objectNameString = "Person";

var person = System.Reflection.Assembly.GetExecutingAssembly().CreateInstance(objectNameString );

If you want to use the value of the objectNameString variable, using a Dictionary or ExpandoObject is the closest you can get:

Dictionary<string, object> someObject = new Dictionary<string, object>();
someObject[objectNameString] = new Person();

Person p = (Person)someObject[objectNameString];

Or, if you only add Persons, the dictionary could look like Dictionary<string, Person>.

I think I get your question. You have a string (e.g. from user input). And you want to create an Person which has the variable name of the string mentioned before.

Dictionary<string, Person> someObject = new Dictionary<string, Person>();
string objectNameString = "objectName";
someObject[objectNameString] = new Person();
