Exception classes in C #

C # exceptions are represented by classes. The exception class in C # is mainly derived directly or indirectly from the System.Exception class. The System.ApplicationException and System.SystemException classes are exception classes that derive from the System.Exception class.

The System.ApplicationException class supports exceptions generated by the application. So all exceptions defined by programmers should be derived from this class.

The System.SystemException class is the base class for all predefined system exceptions.

The following table lists some predefined exception classes derived from the System.SystemException class:

The exception class describes the System.IO.IOException handling of the Istroke O error. System.IndexOutOfRangeException handles errors generated when a method points to an array index that is out of range. System.ArrayTypeMismatchException handles errors generated when array types do not match. System.NullReferenceException handles errors generated when complying with an empty object. System.DivideByZeroException handles errors generated when divided by 00:00. System.InvalidCastException handles errors generated during type conversion. System.OutOfMemoryException handles errors generated by insufficient free memory. The System.StackOverflowException processing stack overflowed the generated error.
