HelpLink =
Message = Attempted to divide by zero.
Source = ConsoleApplication1
StackTrace =    at Program.Main() in C:\...\Program.cs:line 9
TargetSite = Void Main()

HelpLink: This is empty because it was not defined on the exception. HelpLink is a string property.

Message: This is a short description of the exception's cause. Message is a read-only string property.

Source: This is the application name. Source is a string property that can be assigned to or read from.

StackTrace: This is the path through the compiled program's method hierarchy that the exception was generated from.

TargetSite: This is the name of the method where the error occurred. This property helps simplify what part of the errors are recorded.
