xyExtensions

Extracted component of xyToolz — source is maintained in the main xyToolz repository; this package exposes only this module standalone.

This provides some hyper useful methods for problems that where nonexistent before...

Extension methods for string, byte[], List<T>, and Dictionary<TKey,TValue>.

Install

dotnet add package xyExtensions

Contents

    • ToUtf8(this byte[]) — decode bytes to a UTF-8 string.
    • ToBase(this byte[]) — encode bytes to Base64.

  • xyStringExtensions

    • Repeat(this string, ushort count) — repeat a string.
    • Reverse(this string) / ReverseUnicode(this string) — reverse characters (Unicode-safe variant included).
    • ToBytes(this string) — UTF-8 encode to bytes.
    • BaseToBytes(this string) — decode a Base64 string to bytes.
    • IsNullOrEmpty(this string), IsNullOrWhitespace(this string).

  • xyListExtensions

    • FillWithNumbers(this IList<int>, int limit) — fill with 0..limit.
    • AddEvenNumbers(this IList<int>, int limit) — append even numbers up to limit.
    • AddOddNumbers(this IList<int>, int limit) — append odd numbers up to limit.

  • xyDictionaryExtensions

    • GetOrAdd<TKey,TValue>(this Dictionary<TKey,TValue>, TKey, TValue) — single-lookup get-or-add via CollectionsMarshal.

Example

string base64 = "hello".ToBytes().ToBase();
string doubled = "ab".Repeat(3);           // "ababab"
bool empty = someString.IsNullOrWhitespace();

var dict = new Dictionary<string, int>();
int value = dict.GetOrAdd("key", 42);
