CaseConverter

CaseConverter can be used to change the case of different strings.

Reference namespace: ByteDev.Strings.Case.

CaseConverter has the following methods:

• ToCamelCase
• ToKebabCase
• ToPascalCase
• ToSnakeCase
• ToSnakeUpperCase

string s1 = CaseConverter.ToCamelCase("snake_case", CaseType.SnakeCase);   // "snakeCase"

string s2 = CaseConverter.ToPascalCase("kebab-case", CaseType.KebabCase);  // "KebabCase"

bool isPascalCase = s2.IsPascalCase();   // true

There are also a number of case related string extension methods:

• IsCamelCase
• IsKebabCase
• IsPascalCase
• IsSnakeCase
• IsSnakeUpperCase
• IsCaseType

---

StringCommands

Various StringCommands are included that encapsulate different string operations.

Reference namespace: ByteDev.Strings.StringCommands.

var c1 = new CaseToLowerCommand().SetValue("John Smith");
var c2 = new CopyPasteCommand(0, 4, 0).SetValue("John Smith");

IStringCommandInvoker invoker = new StringCommandInvoker();

invoker.SetCommands(c1, c2);
invoker.Invoke();

// c1.Result == "john smith" 
// c2.Result == "JohnJohn Smith"

Commands can also be chained together using the StringChainedCommand:

// Note: we don't have to call SetValue on each command just on StringChainedCommand
// as this will provide the initial value.

var commands = new List<StringCommand>
{
    new CaseToLowerCommand(),
    new InsertCommand(100, " lives in England."),
    new CutPasteCommand(5, 5, 0)
};

var c1 = new StringChainedCommand(commands).SetValue("John Smith");

IStringCommandInvoker invoker = new StringCommandInvoker();

invoker.SetCommands(c1);
invoker.Invoke();

// command.Result == "smithjohn  lives in England."

---

ToStringBuilder

The assembly also contains the type ToStringBuilder to help return string representations of an object when overriding it's ToString method.

Reference namespace: ByteDev.Strings.

public class MyClass
{
    public string Name => "John";

    public string Age => null;

    public IEnumerable<string> Address => new List<string>
    {
        "123 Highstreet",
        "London",
        "UK"
    };

    public override string ToString()
    {
        return new ToStringBuilder()
            .WithNullValue("<null>")
            .WithStringQuoteChar('\'')
            .With(nameof(Name), Name)
            .With(nameof(Age), Age)
            .With(nameof(Address), Address)
            .Build();
    }
}

// ...
string s = new MyClass().ToString();

// s == "Name: 'John', Age: <null>, Address: { '123 Highstreet', 'London', 'UK' }"

---

Masker

Use the Masker type to help mask different types of strings.

Reference namespace: ByteDev.Strings.Masking.

// Initialize Masker type

var options = new MaskerOptions
{
    MaskChar = '#',
    MaskSpace = true
};

var masker = new Masker(options);

// Mask a payment card number

string card = masker.PaymentCard("4111111111111111");

// card == "############1111"

// Mask an email address

string email = masker.EmailAddress("[email protected]");

// email == "j#########@#####.co.uk"

// Mask a custom string

string custom = masker.Custom("12345", 1, 2);

// custom == "1##45"
