Error: Any departure from the expected behavior of the system or program, which stops the working of the system is an error.
Exception:Any error or problem which one can handle and continue to work normally.
Note that in Java a compile time error is normally called an "error," while a runtime error is called an "exception."
Errors don't have subclasses while exception has two subclasses, they are compile time exception or checked exception (ClassNotFound Exception, IOException, SQLException etc.) and runtime or unchecked exception(ArrayIndexOutOfBounds Exception, NumberFormat Exception).

What is the function of catch Exception E?
In Java, if there is a run-time error then it allows the user to explicitly handle it by catching it in the catch block. If there is any error in the try block of code, automatically the flow control will be transferred to the catch block. Here Exception e indicates any exception. The same is true in both Visual Basic and C#. This is seen in the try {} catch (Exception e) {} blocks. Which then function as the previous poster said. == == == ==
How do you use exception in c sharp?
Exceptions are the error handling mechanism of C#. When an error occurs, an exception is thrown using this syntax: void BadMethod() { bool Error = true; if (Error) { throw new Exception("Whoops!"); } } Methods can then handle exceptions using a try/catch/finally syntax. The code that you are trying to execute goes between a try { } block, the code to handle the error goes between the catch { } block. Any code that you put between the finally { } block will always execute after the exception handling code is complete (or if an error did not occur). void test() { try { BadMethod(); catch (Exception ex) { Console.WriteLine("An error occured. The description is: " + ex.Description); } finally { Console.WriteLine("I'm done!"); } }
Does exception always signal an error?
It depends on exactly how you define an error. If an exception is thrown, then it means something has gone wrong. Some Exceptions, such as a NullPointerException, will almost certainly signal an error in your code or data. Others, such as IOExceptions, can be caused by things outside your control, and would probably not be considered errors.
What is difference between exception and error in java and explain using a program?
Error occurs at runtime and cannot be recovered, Outofmemory is one such example. Exceptions on the other hand are due conditions which the application encounters, that can be recovered such as FileNotFound exception or IO exceptions
Why do you need exception handling codes in a program?
separating error handling code from 'regular' code
