Examples
The following code example demonstrates how to use All to determine whether all the elements in a sequence satisfy a condition. Variable allStartWithB is true if all the pet names start with 'B' or if the pets array is empty.
The Boolean value that the All method returns is typically used in the predicate of a where clause (Where clause in Visual Basic) or a direct call to the Where method. The following example demonstrates this use of the All method.
