範例
在這個範例中,會具現化 UnicodeCharacterRangeCollection,並且對它執行數項作業。
Dim UCRC As UnicodeCharacterRangeCollection = New UnicodeCharacterRangeCollection()
' add three UnicodeCharacterRange objects
UCRC.Add("A", 26)
UCRC.Add("a", 26)
UCRC.Add("0", 10)
Dim countOfRanges As Integer = UCRC.Count ' 3
' this is true because collection contains the exact range
Dim thisIsTrue As Boolean = UCRC.Contains(New UnicodeCharacterRange("A", 26))
' this is false because collection does not contain exact range
Dim thisIsFalse As Boolean = UCRC.Contains(New UnicodeCharacterRange("a", 25))
' does not remove because the exact range: '0', 11 does not exist
UCRC.Remove(New UnicodeCharacterRange("0", 11))
' removes because the exact range '0', 10 does exist
UCRC.Remove(New UnicodeCharacterRange("0", 10))
Dim newCountOfRanges As Integer = UCRC.Count ' 2
' idxOfLowerCase = 1 (2nd range added)
Dim idxOfLowerCase As Integer = UCRC.IndexOf(New UnicodeCharacterRange("a", 26))
' idxOfDigits = -1 because that range does not exist (it was removed)
Dim idxOfDigits As Integer = UCRC.IndexOf(New UnicodeCharacterRange("0", 10))
' create an array of UnicodeCharacterRange
Dim UCRArray(UCRC.Count) As UnicodeCharacterRange
' copy from the collection to the array
UCRC.CopyTo(UCRArray, 0)
UnicodeCharacterRangeCollection UCRC = new UnicodeCharacterRangeCollection();
// add three UnicodeCharacterRange objects
UCRC.Add('A', 26);
UCRC.Add('a', 26);
UCRC.Add('0', 10);
int countOfRanges = UCRC.Count; // 3
// this true because collection contains the exact range
bool thisIsTrue = UCRC.Contains(new UnicodeCharacterRange('A', 26));
// this is false because collection does not contain exact range
bool thisIsFalse = UCRC.Contains(new UnicodeCharacterRange('a', 25));
// does not remove because the exact range: '0', 11 does not exist
UCRC.Remove(new UnicodeCharacterRange('0', 11));
// removes because the exact range '0', 10 does exist
UCRC.Remove(new UnicodeCharacterRange('0', 10));
int newCountOfRanges = UCRC.Count; // 2
// idxOfLowerCase = 1 (2nd range added)
int idxOfLowerCase = UCRC.IndexOf(new UnicodeCharacterRange('a', 26));
// idxOfDigits = -1 because that range does not exist (it was removed)
int idxOfDigits = UCRC.IndexOf(new UnicodeCharacterRange('0', 10));
// create an array of UnicodeCharacterRange
