String extensions

The MADE.Data.Converters.Extensions.StringExtensions class provides extension methods for common string manipulation and parsing operations. These cover the transformations you'd otherwise implement as utility methods in every project.

Text formatting

ToTitleCase

Converts a string to title case (capitalizing the first letter of each word):

string title = "hello world".ToTitleCase(); // "Hello World"

ToDefaultCase

Converts a string to lowercase:

string lower = "HELLO".ToDefaultCase(); // "hello"

Truncate

Truncates a string to a specified maximum length:

string preview = "This is a long description of a product".Truncate(20);
// "This is a long descr"

URL slug generation with ToSlug

Converts a string to a URL-friendly slug by removing diacritics, replacing non-alphanumeric characters with hyphens, and lowercasing. This is essential for generating clean URLs from user input or content titles.

string slug = "How To Build & Publish NuGet Packages!".ToSlug();
// "how-to-build-publish-nuget-packages"

string international = "Cafe\u0301 Résumé".ToSlug();
// "cafe-resume"

The slug generator handles Unicode diacritics correctly, collapsing accented characters to their base forms.

Base64 encoding

Convert strings to and from Base64:

string encoded = "Hello, World!".ToBase64();     // "SGVsbG8sIFdvcmxkIQ=="
string decoded = encoded.FromBase64();             // "Hello, World!"

Safe numeric parsing

The standard int.Parse and double.Parse methods throw exceptions on invalid input. These extensions return null instead, which is cleaner when you're dealing with user input or configuration values that might not be valid:

// Returns null instead of throwing on invalid input
int? count = "42".ToNullableInt();        // 42
int? invalid = "not-a-number".ToNullableInt(); // null

float? price = "19.99".ToNullableFloat();  // 19.99f
double? rate = "0.05".ToNullableDouble();  // 0.05

// Non-nullable variants (return 0 on failure)
int count = "42".ToInt();           // 42
float price = "19.99".ToFloat();    // 19.99f
double rate = "0.05".ToDouble();    // 0.05

Boolean parsing with ToBoolean

Parses a string to a boolean value:

bool isEnabled = "true".ToBoolean();  // true
bool isActive = "false".ToBoolean();  // false

Stream conversion with ToMemoryStreamAsync

Converts a string to a MemoryStream, useful when an API expects a stream but you have string content:

using var stream = await jsonContent.ToMemoryStreamAsync();
await blobClient.UploadAsync(stream);
