Since the version 2.5.0.2020 of LeoCorpLibrary, a new namespcae has been added: LeoCorpLibrary.Extensions. In this namespace, there is extensions for common types such as string, int, arrays...

If you wanna use those extensions, import the namespace:

C#

using LeoCorpLibrary.Extensions;

VB

Import LeoCorpLibrary.Extensions

Variation 2 This method has one argument:

Here's an example of usage:

C#

// Variation 1
int numberOfWords = "Hello, this is a test sentence!".CountWords();

// Variation 2
string[] wordSeparator = { " ", ",", ":", "!", "?", ";", "." };
int numberOfWords = "Hello, this is a test sentence!".CountWords(wordSeparator);

VB

' Variation 1
