🎯 Common Extensions

String Extensions

using DKNet.Fw.Extensions;

// Email validation
var email = "[email protected]";
if (email.IsValidEmail())
{
    // Valid email
}

// URL validation
var url = "https://example.com";
if (url.IsValidUrl())
{
    // Valid URL
}

// Null or whitespace check
if (string.IsNullOrWhiteSpace(name))
{
    // Empty
}

// Truncate string
var truncated = longText.Truncate(100); // Max 100 chars

// To camel case
var camelCase = "HelloWorld".ToCamelCase(); // "helloWorld"

// To pascal case
var pascalCase = "hello_world".ToPascalCase(); // "HelloWorld"

// To snake case
var snakeCase = "HelloWorld".ToSnakeCase(); // "hello_world"

// Remove special characters
var cleaned = dirtyString.RemoveSpecialCharacters();

// Safe substring
var part = text.SafeSubstring(0, 10); // Won't throw if text is shorter

Type Extensions

using DKNet.Fw.Extensions;

// Enum conversion with validation
if (typeof(OrderStatus).TryConvertToEnum("Pending", out OrderStatus status))
{
    // status = OrderStatus.Pending
}

// Type checking
if (myObject.IsNumericType())
{
    // It's a number
}

if (typeof(string).IsNullableType())
{
    // Check if nullable
}

// Get default value
var defaultValue = typeof(int).GetDefaultValue(); // 0

// Property exists check
if (typeof(Product).HasProperty("Name"))
{
    // Property exists
}
