StringExtensions

c# StringExtensions Library provides comprehensive string extension methods that go behold just the common string validation methods extending the .Net System.string class. The idea to create such a library was motivated by the lack of such a StringUtil library such as org.apache.commons.lang3.StringUtils in the the .Net realm. The aim of this library is to serve as a goto library for those wishing to have such a library readily available to incorporate in to new or existing projects.

Installation

Usage

Once you have installed the String extension library within your project. String extensions functions will be available on all string types

	\\do something
}
