Can we interrupt creating an object in constructor

Question

Could you help me please. I have one idea but don\'t know how can I implement it.

So the question is: Can we interrupt creating an object in constructor i.e.

Answer 1

No it is not possible directly.

You could throw an exception and add the required code to check for the exception and assign null to you variable.

A better solution would be to use a Factory that would return null if some condition fail.

var someClass = SomeClassFactory.Create(someCriteria);
if(someClass != null)
{
}
