Console.WriteLine($"Hello, {name}!");
var number = Prompt.Input<int>("Enter any number");
Console.WriteLine($"Input = {number}");
Confirm
var answer = Prompt.Confirm("Are you ready?");
Console.WriteLine($"Your answer is {answer}");
Password
var secret = Prompt.Password("Type new password");
Console.WriteLine("Password OK");
Select
var city = Prompt.Select("Select your city", new[] { "Seattle", "London", "Tokyo" });
Console.WriteLine($"Hello, {city}!");
MultiSelect (Checkbox)
var cities = Prompt.MultiSelect("Which cities would you like to visit?", new[] { "Seattle", "London", "Tokyo", "New York", "Singapore", "Shanghai" }, pageSize: 3);
Console.WriteLine($"You picked {string.Join(", ", cities)}");
List

[Required]
[InlineItems("Seattle", "London", "Tokyo")]

public bool? Ready { get; set; }
}
var result = Prompt.Bind<MyFormModel>();
Configuration
