SweetMeSoft.Tools

Library with a set of reusable tools and utilities for common tasks.

Description

SweetMeSoft.Tools is a library for .NET Standard 2.1 that groups a collection of static helper classes to perform a variety of tasks, from type conversions and validations to email sending and data encryption.

Main Components

Converters

Methods for data type conversions, handling local culture for decimal separators.

• StringToDouble(string)
• StringToFloat(string)
• StringToDecimal(string)
• StringToInt(string)
• IntToString(int)
• DecimalToString(decimal)
• StringToBool(string)

Email

A class for sending emails via SMTP.

• Send(EmailOptions): Sends an email configured through an EmailOptions object.
  • Supports preconfigured hosts like Gmail, Outlook and Webmail.
  • Allows normal and embedded (linked) attachments.
  • Requires EmailOptions.Sender and EmailOptions.Password to be set statically before use.

Reflections

Utilities that use reflection.

• CleanVirtualProperties<T>(T entity): Removes circular references in objects (commonly database entities) by serializing and deserializing the object with ReferenceLoopHandling.Ignore. Very useful for preparing data to be sent through an API.

Security

Methods for password hashing and reversible encryption.

• HashPasswordIrreversible(string): Creates a hash of a password using PBKDF2 with a salt.
• VerifyHashedPasswordIrreversible(string, string): Compares a plain text password with its hash.
• CipherPasswordReversible(string, key, iv): Encrypts text using AES.
• DecipherPassword(string, key, iv): Decrypts encrypted text with AES.

Utils

A set of miscellaneous utilities.

• GetException(Exception): Gets the innermost exception message.
• GetRandomNumber(int): Generates a string of N random digits.
• WriteToAPath(StreamFile, path): Saves a StreamFile to a disk path.
• StringMatchCompare(list, chain, threshold): Performs a "fuzzy" string comparison to find similarities.
• MinifyJson(string): Removes whitespace from a JSON string.

Validators

Common validation methods.

• IsValidEmail(string): Verifies if a string has a valid email format.
• IsValidPassword(string): Verifies if a password meets complexity requirements (uppercase, lowercase, numbers, symbols and minimum length).

Dependencies

• Microsoft.CSharp
• Newtonsoft.Json
• SweetMeSoft.Base

Installation

dotnet add package SweetMeSoft.Tools

Usage Example

using SweetMeSoft.Tools;

// --- Validation ---
bool isValid = Validators.IsValidEmail("test@example.com");

// --- Security ---
string password = "MySecurePassword123!";
string hashedPassword = Security.HashPasswordIrreversible(password);
bool isPasswordCorrect = Security.VerifyHashedPasswordIrreversible(hashedPassword, password);

// --- Converters ---
int number = Converters.StringToInt("123.45"); // Results in 123
