C# Programming - Exception Handling

1. try blocks cannot be nested.
2. In one function, there can be only one try block.
3. An exception must be caught in the same function in which it is thrown.
4. All values set up in the exception object are available in the catch block.
5. While throwing a user-defined exception multiple values can be set in the exception, object.
