public class SuperClass { }

public class SubClass1 : SuperClass { }
public class SubClass2 : SuperClass { }

public void DoStuff(SuperClass arg)
{
if (arg is instance of SubClass1, but not an instance of SubClass2) // How to check this ?
{
var data = (SubClass1) arg;
// Do stuff
}
}

Sagen wir, ich habe diese Superklasse:
[code]public class SuperClass { }
[/code]
Und diese Unterklassen:
[code]public class SubClass1 : SuperClass { }
public class SubClass2 : SuperClass { }
[/code]
Wir haben diesen Kundencode:
[code]public void DoStuff(SuperClass arg)
{
if (arg is instance of SubClass1, but not an instance of SubClass2) // How to check this ?
{
var data = (SubClass1) arg;
// Do stuff
}
}
[/code]
Wie überprüfe ich, ob arg nur eine SubClass1 oder nur eine SubClass2 ist?
