如何检查类的属性是否抛出异常

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.

Answer 1

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.
