2,115 PointsWhat is "ex"? where did it come from? Why does it work?
I understand that Exception is from System, but what is this ex "keyword".

So the Exception ex is the type then the name of that variable. It could have been for another function something like string MyString.
So you're saying any parameter sent to my catch method of the type Exception I would reference it as ex.
Then you can later drill down into that object to find other things, like the exception's message.

2,115 PointsBut why is it "ex" is that syntax?
Kevin Gates
15,053 PointsHi Matthew De-Veale Cutts ,
the ex specifically is the name you chose to give the variable.
So it's setup in a TYPE Name relationship. So the TYPE is an Exception and the Name is the name of the variable. This example chose ex but it could be exception or even random like BadNews.
Make sense?

2,115 PointsKevin Gates I think i get it! So Exception is a type (like int, double, etcetc) and ex is a variable name (like X)
