public class Person
{
public bool name;
}

Do you mean at runtime?– adv12Commented Nov 13, 2015 at 14:35

Cannot be done. Cannot think of why anyone would want to do that.– JJFCommented Nov 13, 2015 at 14:39

You can create a typegeneric type, so you can create a Person with bool name and another Person with string name. Anyway, probably you are thinking to complex leading to this idea.– AntiHeadshotCommented Nov 13, 2015 at 14:39

This might be an X-Y problem. What initial problem gave rise to this attempted solution?– adv12Commented Nov 13, 2015 at 14:41

Ok, I'm searching for different solutions, but I had this doubt so I decided to post here, thanks for your answers. Anyway, I'm working with Entity framework, ASP.NET MVC in azure, my application uses n databases, so I have to constantly change context in order to synchronize my data, 2 databases use same context definition (exactly same tables), but now one table in just one of these databases had a different property, so I was trying to change just one property type from my context without having to create another class or a generic type.– Antonio CorreiaCommented Nov 13, 2015 at 15:03

If you want to do that at runtime you have different options. Some of them:
1) Make the property object and check types wherever you use it:
public class Person
{
public object Name;
}
2) Create a generic type for Person that allows you to define different instances of the class for different types:
public class Person<T>
{
public T Name;
}
var boolPerson = new Person<bool>();
boolPerson.Name = true;
var stringPerson = new Person<string>();
stringPerson.Name = "aString";
However you should explain why do you want to do this as there could be a better solution.
Have a look at this (you can create a dynamic object and change that object at runtime).
