CompareInfo.LastIndexOf メソッド (String, String, Int32, Int32)
指定した部分文字列を検索し、検索対象文字列の指定したインデックスで終了し、指定した数の要素を含んでいる範囲内で、その部分文字列が最後に出現する位置の 0 から始まるインデックス番号を返します。
Overloads Public Overridable Function LastIndexOf( _
ByVal source As String, _ ByVal value As String, _ ByVal startIndex As Integer, _ ByVal count As Integer _) As Integer
[C#]
public virtual int LastIndexOf(stringsource,stringvalue,intstartIndex,intcount);
[C++]
public: virtual int LastIndexOf(String* source,String* value,intstartIndex,intcount);
[JScript]
public function LastIndexOf(
source : String,value : String,startIndex : int,count : int) : int;
パラメータ
- source
検索対象の文字列。 - value
source 内で検索する文字列。 - startIndex
後方検索の開始位置を示す 0 から始まるインデックス。 - count
検索対象の範囲内にある要素の数。
戻り値
startIndex で終了し、count で指定した数の要素を含んでいる source の範囲内で value が見つかった場合は、最後に見つかった位置の 0 から始まるインデックス番号。それ以外の場合は -1。
例外
| 例外の種類 | 条件 |
|---|---|
| ArgumentNullException | source が null 参照 (Visual Basic では Nothing) です。
または value が null 参照 (Nothing) です。 |
| ArgumentOutOfRangeException | startIndex が source の有効なインデックスの範囲外の値です。
または count が 0 未満です。 または startIndex および count が source 内の有効な部分を指定していません。 |
解説
検索範囲の文字列内で、検索は startIndex から開始して逆方向に進み、 startIndex- count + 1 の位置で終了します。
このオーバーロードは、カルチャを考慮した検索を実行します。カルチャによっては、合字の 'Æ' (U+00C6) など構成済み文字を表す Unicode 値と、この文字の構成要素が "AE" (U+0041、U+0045) のように正しい順序で出現したものが等価であると見なします。Unicode 値を比較する番号順 (カルチャを考慮しない) 検索を実行するには、 CompareOptions 値をパラメータとして受け取るオーバーロードのいずれかを使用して、 Ordinal 値を使用します。
使用例
[Visual Basic, C#, C++] 次に示すのは、文字列の一部分の、最初と最後に出現する文字または部分文字列のインデックスを調べるコード例です。
