C# 7 and .NET Core: Modern Cross-Platform Development - Second Edition

Overview of this book

If you want to build powerful cross-platform applications with C# 7 and .NET Core, then this book is for you. First, we’ll run you through the basics of C#, as well as object-oriented programming, before taking a quick tour through the latest features of C# 7 such as tuples, pattern matching, out variables, and so on. After quickly taking you through C# and how .NET works, we’ll dive into the .NET Standard 1.6 class libraries, covering topics such as performance, monitoring, debugging, serialization and encryption. The final section will demonstrate the major types of application that you can build and deploy cross-device and cross-platform. In this section, we’ll cover Universal Windows Platform (UWP) apps, web applications, mobile apps, and web services. Lastly, we’ll look at how you can package and deploy your applications so that they can be hosted on all of today’s most popular platforms, including Linux and Docker. By the end of the book, you’ll be armed with all the knowledge you need to build modern, cross-platform applications using C# and .NET Core.

Preface

Reading and writing with streams


A stream is a sequence of bytes.

There is an abstract class named Stream that represents a stream. There are many classes that inherit from this base class, so they all work the same way. In the following table are some of the common members of the Stream class:

Member

Description

CanRead, CanWrite

This determines whether you can read from and write to the stream

Length, Position

This determines the total number of bytes and the current position within the stream

Dispose()

This closes the stream and releases its resources

Flush()

If the stream has a buffer, then it is cleared and written to the underlying stream

Read(), ReadAsync()

This reads a specified number of bytes from the stream into a byte array and advances the position

ReadByte()

This reads the next byte from the stream and advances the position

Seek()

This moves the position to the specified position (if CanSeek is true)

Write(), WriteAsync()

This writes the...
