This article mainly introduces the relevant knowledge of "how to develop interactive command line application in C #". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "how to develop interactive command line applications in C #" can help you solve the problem.

Preface

If you have developed vue applications, you should be impressed by its interactive command line:

It allows you to create vue applications without any programming experience and just answer questions.

Although as .NET, we don't use the command line most of the time, we still want to be able to develop such interactive command-line applications, such as code generators, in C #.

Sharprompt introduction

Sharprompt is an interactive command line application framework based on C #, which has the following characteristics:

Multi-platform support

Support common prompts (normal input / password / options, etc.)

Model-based prompts are supported (in preview)

Let's demonstrate how to use Sharprompt to generate an interactive command-line application.

The code is as follows:

Console.OutputEncoding = Encoding.UTF8;Prompt.ColorSchema.Select = ConsoleColor.DarkCyan;var type = Prompt.Select ("database type", new [] {"Oracle", "SQL Server", "MySQL", "PostgreSQL", "MariaDB"}, defaultValue: "MySQL", pageSize: 3); var server = Prompt.Input ("service address"); Prompt.ColorSchema.Answer = ConsoleColor.DarkRed;var name = Prompt.Input ("user name"); var password = Prompt.Password ("password") Console.WriteLine ($"you typed {type} {server} {name} {password}"); var confirm = Prompt.Confirm ("continue"); Console.WriteLine ($"your choice is {confirm}!"); this is the end of the introduction on "how to develop interactive command line applications in C#".
