How to check if a property of a class has thrown an exception

Question

How can I check if a getter/setter of a property in a class, has thrown an exception? (Before accessing it)

Example

For example in this picture, the ExitTime property of a process threw an exception of type System.InvalidOperationException

If I use process.ExitTime, I get another runtime exception: No process is associated with this object.

Good question. I've had Properties that have caused exceptions, especially if a Property that is also a Factory (Get Property creates an instance if it doesn't already exist). In that case, I never get an error, and it can be hard to track down. — user153923

Technically it hasn't thrown an exception before you use the accessor method. The only reason that window shows it is because it tried to get the property.

So you can't detect this. All you can do is wrap the accessing code in a try/catch block to catch the exception when it is thrown.
