Description

StringExtensions

The StringExtensions project is a collection of extension methods for the string class in C#. These methods provide additional functionality for working with strings,

such as capitalizing the first letter, converting the string to lowercase, counting the number of occurrences of a specific character, and checking the encoding of the string.

ArrayExtensions

The ArrayExtensions project is a collection of extension methods for arrays in C#. These methods provide additional functionality for

working with arrays, such as appending elements, clearing the array, counting the number of occurrences of a specific element, finding the index of an element,

inserting an element at a specific index, and reversing the order of the elements in the array.

Tests

Both projects have corresponding unit tests projects, these unit tests for these extension methods using xUnit and FluentAssertions.

Methods

The following methods are included in the StringExtensions class:

• Capitalize: This method capitalizes the first character of a string.
• Count: This method counts the number of occurrences of a specified character in a string.
• IsAllNum: This method determines whether a string consists only of numeric characters.
• IsASCII: This method determines whether a string consists only of ASCII characters.
• IsUTF8: This method determines whether a string is encoded in UTF-8 format.
• IsUTF16: This method determines whether a string is encoded in UTF-16 format.
• IsDecimal: This method determines whether a string represents a valid decimal number.
• IsDigit: This method determines whether a string consists only of digits.
• IsIdentifier: This method determines whether a string is a valid identifier.
• IsLower: This method determines whether a string consists only of lowercase characters.
• IsUpper: This method determines whether a string consists only of uppercase characters.
• ToJson: This method generates a JSON string from a source string with the format "key:value|Key:value".
• Reverse: This method reverses the order of the characters in a string.
• IsAlpha: This method determines whether a string consists only of alphabetic characters
• ToInt16: This method converts a string to an int16 value
• ToInt32: This method converts a string to an int32 value
• ToInt64: This method converts a string to an int64 value
• ToDecimal: This method converts a string to an decimal value
• ToFloat: This method converts a string to an float value
• ToBoolean: This method converts a string to an boolean value
• ExtractQuotedText: This method extracts the text inside a quote inside a string.

The following methods are included in the ArrayExtensions class:

• Append: Adds one or more elements to the end of an array.
• Clear: Removes all elements from an array.
• Count: Counts the number of occurrences of a specific element in an array.
• Index: Returns the index of a specific element in an array.
• Insert: Inserts an element at a specific index in an array.
• Revert: Reverses the order of the elements in an array.
• Remove: Removes all occurrences of a specific element from an array.

Usage

To use these extension methods, simply call them on any string value like this:

string input = "hello";
string output = input.Capitalize();

// Result: Hello
