CSharp-Compile-Run-code

.NET is Microsoft’s free and open source framework for developing native software applications on Linux, macOS, and Windows. The power of cross-platform development allows developers to design, code, and run programs on a wide array of platforms.

This course is an introduction to developing .NET applications using C#. You’ll start start with a comprehensive review of C# and computer programming fundamentals: data types, conditionals, loops, methods, and more. You’ll then review the basics of object-oriented programming before diving into methods, exception handling, delegation, and events. With this foundation, you’ll continue building interfaces, collections, database operations, and multithreading. You’ll wrap up with process improvements using dynamic binding, garbage collection, and unmanaged resources.

By the end of this course, you’ll have hands-on experience with C# and .NET, and be ready to build applications using object-oriented programming principles on almost any platform.

# The `Exception` class

An exception is nothing more than a class. So, when an exception is generated, an object of a given exception type is created and thrown.

The base class of all exceptions in .NET is the `Exception` class. It defines several properties that can be used to obtain more information about the exception that’s occurred.

- `InnerException`: This stores the exception object that caused the current exception.
- `Message`: This stores the exception’s textual information.
- `Source`: This stores information about an object or an assembly where the exception was thrown.
- `StackTrace`: This stores the entire method call stack that led to the exception.
- `TargetSite`: This stores the method name where the exception occurred.

Let’s see the contents of the properties using the following example:
