General Catch Handler
A catch block which will catch any exception is called a general catch handler. A general catch handler does not specify any parameter and can be written as

try
{
// Statement which causes an exception
}

catch //No parameters
{
//Handles any type of exception
}

catch(Exception e) can handle all the exceptions thrown by the C# code and therefore can be used as a general catch handler.

If the program uses libraries written in other languages, then there may be an exception that is not derived from the class Exception. Such exceptions can be handled by the parameter-less catch statement.

This handler is always placed at the end. Since there is no parameter, it does not catch any information about the exception and therefore we do not know what went wrong.
