Beginning C# 7 Hands-On ??? Advanced Language Features

By: Tom Owsiak

Overview of this book

Beginning C# 7 Hands-On – Advanced Language Features assumes that you’ve mastered the basic elements of the C# language and that you're now ready to learn the more advanced C# language and syntax, line by line, in a working Visual Studio environment. You'll learn how to code advanced C# language topics including generics, lambda expressions, and anonymous methods. You'll learn to use query syntax to construct queries and deploy queries that perform aggregation functions. Work with C# and SQL Server 2017 to perform complex joins and stored procedures. Explore advanced file access methods, and see how to serialize and deserialize objects – all by writing working lines of code that you can run within Visual Studio. This book is designed for beginner C# developers who have mastered the basics now, and anyone who needs a fast reference to using advanced C# language features in practical coding examples. You'll also take a look at C# through web programming with web forms. By the time you’ve finished this book, you’ll know all the critical advanced elements of the C# language and how to program everything from C# generics to XML, LINQ, and your first full MVC web applications. These are the advanced building blocks that you can then combine to exploit the full power of the C# programming language, line by line.

Making a directory and creating a file from Command Prompt


Now, you want to make sure that you have the samplefile.txt file. So, to do that in Windows, type cmd, which is short for Command Prompt, and open that. At the C:\> prompt, start by typing cd.. to go up one level and then cd.. again to go up another level. Then enter cd data to change to the data directory. The system responds that this path does not exist, as you can see in Figure 5.5.3; so, we'll have to create the path and make the file:

Figure 5.5.3: The system indicates that the path c:\>data does not exist

To create the path, type the following at command prompt:

C:\>md data

Then, enter the following to change into that directory:

C:\>cd data

Next, type the following to show you the list of files in the directory:

C:\data\dir

As you can see in the Figure 5.5.3, there is nothing inside the directory: it's new, we just created it. So, to open a file in Notepad, type the following at the prompt:

C:\data\notepad.exe samplefile...
