UnicodeCharacterRangeCollection.CopyTo 方法

从指定的目标数组索引处开始，将当前 UnicodeCharacterRangeCollection 集合的所有元素复制到指定的一维数组中。

命名空间：  Microsoft.Ink
程序集：  Microsoft.Ink.Analysis（在 Microsoft.Ink.Analysis.dll 中）

语法

声明
Public Sub CopyTo ( _
    array As UnicodeCharacterRange(), _
    index As Integer _
)
用法
Dim instance As UnicodeCharacterRangeCollection
Dim array As UnicodeCharacterRange()
Dim index As Integer

instance.CopyTo(array, index)

public void CopyTo(
    UnicodeCharacterRange[] array,
    int index
)

public:
void CopyTo(
    array<UnicodeCharacterRange^>^ array, 
    int index
)

public void CopyTo(
    UnicodeCharacterRange[] array,
    int index
)

public function CopyTo(
    array : UnicodeCharacterRange[], 
    index : int
)

参数

• array
  类型：array<Microsoft.Ink.UnicodeCharacterRange[]
  用作要将集合中的元素复制到的目标的一维数组。该数组必须具有从零开始的索引。

• index
  类型：System.Int32
  数组参数中从零开始的索引，将从该索引处开始复制。

示例

在此示例中，实例化 UnicodeCharacterRangeCollection 并对它执行几个操作。

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
UnicodeCharacterRange[] UCRArray = new UnicodeCharacterRange[UCRC.Count];
// copy from the collection to the array
UCRC.CopyTo(UCRArray, 0);
