String.IndexOfAny メソッド

Unicode 文字の指定した配列内にある文字がこのインスタンスで最初に見つかった位置のインデックスをレポートします。

オーバーロードの一覧

Unicode 文字の指定した配列内にある文字がこのインスタンスで最初に見つかった位置のインデックスをレポートします。

.NET Compact Framework でもサポート。

[Visual Basic] Overloads Public Function IndexOfAny(Char()) As Integer

[C#] public int IndexOfAny(char[]);

[C++] public: int IndexOfAny(__wchar_t __gc[]);

[JScript] public function IndexOfAny(Char[]) : int;

Unicode 文字の指定した配列内にある文字がこのインスタンスで最初に見つかった位置のインデックスをレポートします。検索は、指定した文字位置から開始されます。

.NET Compact Framework でもサポート。

[Visual Basic] Overloads Public Function IndexOfAny(Char(), Integer) As Integer

[C#] public int IndexOfAny(char[], int);

[C++] public: int IndexOfAny(__wchar_t __gc[], int);

[JScript] public function IndexOfAny(Char[], int) : int;

Unicode 文字の指定した配列内にある文字がこのインスタンスで最初に見つかった位置のインデックスをレポートします。検索は指定した文字位置から開始され、指定した数の文字位置が検査されます。

.NET Compact Framework でもサポート。

[Visual Basic] Overloads Public Function IndexOfAny(Char(), Integer, Integer) As Integer

[C#] public int IndexOfAny(char[], int, int);

[C++] public: int IndexOfAny(__wchar_t __gc[], int, int);

[JScript] public function IndexOfAny(Char[], int, int) : int;
