SmartMapValidator 1.2.2

SmartMapValidator

🔧 SmartMapValidator is a lightweight, attribute-based object mapping and validation library for C#. It helps you map DTOs to entities and validate properties using simple custom attributes.

🚀 Features

• ✅ Custom mapping with [MapTo] attribute
• 🚫 Skip mapping with [MapIgnore] attribute
• 📋 Built-in validation support with [Required] and [Range] attributes
• 🧩 Modular and extensible architecture

📦 Installation

You can use it locally as a class library or package it as a NuGet package.

🔹 Add project reference manually:

dotnet add reference ../SmartMapValidator/SmartMapValidator.csproj

🧪 Usage Example

Define a DTO and Entity:

public class UserDto
{
    [Required]
    public string Name { get; set; }

    [MapTo("UserAge")]
    [Range(18, 99)]
    public int Age { get; set; }

    [MapIgnore]
    public string Secret { get; set; }
}

public class UserEntity
{
    public string Name { get; set; }
    public int UserAge { get; set; }
}

Mapping:

var dto = new UserDto
{
    Name = "Aysel",
    Age = 25,
    Secret = "Hidden"
};

var entity = SmartMap.Map<UserDto, UserEntity>(dto);

// entity.Name -> "Aysel"
// entity.UserAge -> 25

Validation:

var invalidDto = new UserDto
{
    Name = "",
    Age = 10
};

var result = SmartMap.Validate(invalidDto);

if (!result.IsValid)
{
    Console.WriteLine(result.ToString());
    // Output:
    // Name field cannot be empty.
    // Age must be between 18 and 99.
}
