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 problem

By default, when we print the `DateTime` object, it has an inconvenient format:

using System;

namespace DateTimeFormatting
{
    class Program
    {
        static void Main(string[] args)
        {
            var dateTime = new DateTime(2021, 12, 24, 17, 45, 23); // 12/24/2021 17:45:23
            Console.WriteLine(dateTime);
        }
    }
}

This format may not be user-friendly. Fortunately, there are ways to change the output according to our needs.

# Output format methods

The `DateTime` struct offers several output-formatting methods. Each provides a different output:

 - `ToLocalTime()`: This assumes that the time inside the `DateTime` object is in UTC and converts it to local time.
 - `ToUniversalTime()`: This assumes that the time inside the `DateTime` object is in the local timezone and converts it to UTC.
 - `ToLongDateString()`: This returns a string version of the date with the month written in words.
 - `ToShortDateString()`: This only returns the date.
 - `ToLongTimeString()`: This returns time with seconds.
 - `ToShortTimeString()`: This returns time without seconds.

Let’s see each output:
