I'm trying to get information about which child called parents constructor. I'm not allowed to pass the argument onto the constructor. Is something like this possible?
class Parent {
Parent() {
Console.WriteLine("Child1 called me");
}
}
class Child1: Parent {
string name;
Child1(string name) {
this.name = name;
}
}
class Child2: Parent {
string surname;
Child1(string surname) {
this.surname = surname;
}
}
GetType() will still work here, and is non-virtual (which limits how much trouble you can get into re uninitialized fields, which is a problem when calling virtual methods from a constructor); you can always explore the tree if multiple types are involved:
public Parent()
{
var type = GetType();
while (type != typeof(Parent) && type != null)
{
Console.WriteLine(type.Name);
type = type.BaseType;
}
}
If we have:
class Child3 : Child2
{
public Child3(string surname) : base(surname) { }
}
// ...
new Child3("whatever");
Then this will output:
Child3
Child2
