PageRange Class

Definition

Represents a range of page numbers.

[TypeConverter(typeof(StringTypeConverter))]
public class PageRange : NumberRange

Creating a PageRange instance:

var pageRange = new PageRange("1-5");

//Same as above, PageRange can be implicitly converted from a string
PageRange pageRange2 = "1-5";

Dim pageRange As New PageRange("1-5")

'Same as above, PageRange can be implicitly converted from a string
Dim pageRange2 As PageRange = "1-5"

The range is specified as a string in the following forms or combination thereof:

5	single value
1,2,3,4,5	sequence of values
1-5	closed range
-5	open range (converted to a sequence from 1 to 5)
1-	open range (converted to a sequence from 1 to final page)
all	keyword representing all page numbers.
odd	keyword representing odd page numbers.
even	keyword representing even page numbers.

The value delimiter can be either ',' or ';' and the range separator can be either '-' or ':'. Whitespace is permitted at any point in the input.

Any elements of the sequence that contain non-digit, non-whitespace, or non-separator characters or that are empty are ignored.
