Exception Types

An exception is an object that wraps error details. When an error occurs, the runtime creates and throws an object of a specific exception type.

The Exception class

The base class of all exceptions in .NET is the System.Exception class. It defines several properties that help us understand what went wrong.

• Message: A text description of the error.

• StackTrace: A string showing the method call sequence that led to the exception.

• Source: The name of the application or object that caused the error.

• InnerException: If an exception was triggered by another exception, this property holds the original error.

• TargetSite: The method name that threw the current exception.

The following example demonstrates these properties.
