The Pandatech.BaseConverter library offers robust and flexible base conversion functionalities, enabling seamless transformations between base 10 and base 36 numeral systems. Designed for simplicity and efficiency, it's an essential tool for applications requiring numeral system conversions, particularly useful in scenarios like generating concise, URL-friendly unique identifiers from numeric values. Available as a convenient NuGet package, it integrates effortlessly into your .NET projects.

• Bi-directional Conversion: Supports converting numbers from base 10 to base 36 and vice versa.
• Custom Character Set Configuration: Allows customization of the character set used for base 36 encoding, enabling unique identifier generation tailored to specific requirements.
• Integration with Data Transfer Objects (DTOs): Facilitates the use of base 36 encoded strings in DTOs, enhancing API usability and readability.
• Swagger Integration: Ensures seamless integration with Swagger for API documentation and testing, with support for custom parameter converters.
• Robust Validation: Offers built-in validation for base 36 inputs, ensuring data integrity and error resilience.
• Exception Handling: Provides clear and informative error messages for invalid inputs, aiding in troubleshooting and debugging.

To include Pandatech.BaseConverter in your project, install it as a NuGet package:

Install-Package Pandatech.BaseConverter

Converting from Base 10 to Base 36 (2 overloads for nullable and non-nullable output)

long number = 12345;
string base36Number = BaseConverter.PandaBaseConverter.Base10ToBase36(number);
// Output: base36Number = "9ix"

Converting from Base 36 to Base 10 (nullable input and output)

string base36Number = "9ix";
long? number = BaseConverter.PandaBaseConverter.Base36ToBase10(base36Number);
// Output: number = 12345

Converting from Base 36 to Base 10 (non-nullable input and output)

string base36Number = "9ix";
long number = BaseConverter.PandaBaseConverter.Base36ToBase10NotNull(base36Number, false);
// Output: number = 12345

You can customize the character set used for base 36 encoding to suit your application's needs, for not exposing actual order:

var builder = WebApplication.CreateBuilder(args);
var customCharset = "0123456789abcdefghijklmnopqrstuvwxyz";
builder.Services.ConfigureBaseConverter(customCharset);

Decorate DTO properties with [PandaPropertyBaseConverter] to automatically handle base 36 encoding/decoding:

public class MyDto
{
    [PandaPropertyBaseConverter]
    public long Id { get; set; }
}

Use [PandaParameterBaseConverter] to automatically resolve base 36 encoded parameters in controller actions:

[HttpGet("{id}")]
public async Task<ActionResult<MyDto>> Get([PandaParameterBaseConverter] long id)
{
    // Your logic here
}

Validate base 36 inputs using the ValidateBase36Chars extension method:

string base36Number = "9ix";
bool isValid = base36Number.ValidateBase36Chars();
// Output: isValid = true

builder.Services.AddSwaggerGen(
    options =>
    {
        options.ParameterFilter<PandaParameterBaseConverterAttribute>();
        options.SchemaFilter<PandaPropertyBaseConverterSwaggerFilter>();
    }
);

The library employs ArgumentException to signal invalid inputs, equipped with descriptive messages to facilitate debugging:

try
{
    var result = BaseConverter.PandaBaseConverter.Base36ToBase10("invalid-input");
}
catch (ArgumentException ex)
{
    Console.WriteLine(ex.Message);
    // Handle the exception as needed
}
