Un algoritmo para justificar un string. Me he inspirado en este servicio online: https://onlinetexttools.com/justify-textEjemplo de uso: Dim input As String = "About 20% of oxygen is produced by the Amazon rainforest. The Earth's atmosphere is about 78 percent nitrogen, 21 percent oxygen, and about 1 percent other gases. For the existence of most organisms on the planet, oxygen is a necessary element, it provides the body with energy and removes carbon dioxide. Fortunately, plants constantly replenish the oxygen level of our planet thanks to photosynthesis. During this process, carbon dioxide and water are converted into energy, releasing oxygen as a byproduct. The Amazon rainforest covers 5.5 million square kilometers (2.1 million square miles), recycling much of the Earth's oxygen while absorbing large amounts of carbon dioxide." Dim lineLength As Integer = 50 Dim result As String = UtilString.JustifyText(input, lineLength, justifyLastLine:=True) Console.WriteLine(result)

Algunos atajos a modo de extensiones de métodos para simplificar la generación de excepciones al cumplir cierta condición en un objeto. Ejemplos de uso: - Object.ThrowIf Dim value As Integer = 0 ' value.ThrowIf(Of ArgumentOutOfRangeException)(Function(x) x = 0) value.ThrowIf(Function(x) x = 0, New ArgumentOutOfRangeException(paramName:=NameOf(value)))

- Object.ThrowIfNull Dim obj As Object = Nothing ' obj.ThrowIfNull(Of ArgumentNullException) obj.ThrowIfNull(New ArgumentNullException(paramName:=NameOf(obj)))
- Object.ThrowIfDefault Dim obj As Integer = 0 ' obj.ThrowIfDefault(Of ArgumentNullException) obj.ThrowIfDefault(New ArgumentNullException(paramName:=NameOf(obj)))
