How do I convert PascalCase to kebab-case with C#?

Question

How do I convert a string value in PascalCase (other name is UpperCamelCase) to kebab-case with C#?

e.g. "VeryLongName" to "very-long-name"

Answer 1

Here is how to do that with a regular expression:

public static class StringExtensions {     public static string PascalToKebabCase(this string value)     {         if (string.IsNullOrEmpty(value))             return value;          return Regex.Replace(             value,             "(?<!^)([A-Z][a-z]|(?<=[a-z])[A-Z])",             "-$1",             RegexOptions.Compiled)             .Trim()             .ToLower();     } }
