🚀 ClassExtensions for C#

A set of handy C# extension methods for objects, collections, strings, and streams to make your code cleaner and more expressive.

🟢 Null Checks

bool IsNull(this object obj)
✅ Returns true if the object is null.
bool IsNotNull(this object obj)
✅ Returns true if the object is not null.

void ForAll(this IEnumerable<T> source, Action<T> action)
Executes action for each element. Safe if null.
void Times(this int count, Action<int> action)
Executes actioncount times. Safe if null.
bool IsEmpty(this IEnumerable value) – Checks if empty
bool IsNotEmpty(this IEnumerable value) – Checks if not empty
bool IsNullOrEmpty(this IEnumerable value) – Checks null or empty
bool IsNotNullOrEmpty(this IEnumerable value) – Checks not null and not empty
T Pop<T>(this IList<T> source) – Returns last element and removes it
T Shift<T>(this IList<T> source) – Returns first element and removes it
void Unshift<T>(this IList<T> source, T toAdd) – Adds element at first position
T AnyOne<T>(this IEnumerable<T> source) – Returns any element (throws if null/empty)
bool None<T>(this IEnumerable<T> source, Func<T, bool> predicate = null) – Checks if no elements match the predicate

void EqualJsonCheck(this object obj, object toCompare)
Compares objects via JSON serialization and throws if unequal.
bool IsEqualJson(this object obj, object toCompare)
Returns true if objects are equal via JSON.

string UseFormat(this string text, params string[] @params) – Uses string.Format for placeholders

byte[] ToByteArray(this Stream stream) – Converts a Stream to a byte array
Stream ToStream(this byte[] byteArray) – Converts a byte array to a Stream
