String.EndsWith メソッド (String)
アセンブリ: mscorlib (mscorlib.dll 内)

Dim instance As String Dim value As String Dim returnValue As Boolean returnValue = instance.EndsWith(value)
戻り値
このインスタンスの末尾が value と一致する場合は true。それ以外の場合は false。


このメソッドは、value と、このインスタンスの末尾にある、value とまったく同じ長さの部分文字列とを比較し、両者が等しいかどうかを調べます。等しいという結果を得るためには、value が、この同じインスタンスへの参照であるか、このインスタンスの末尾と一致している必要があります。

String.EndsWith メソッド (String, StringComparison)
アセンブリ: mscorlib (mscorlib.dll 内)

<ComVisibleAttribute(False)> _ Public Function EndsWith ( _ value As String, _ comparisonType As StringComparison _ ) As Boolean
Dim instance As String Dim value As String Dim comparisonType As StringComparison Dim returnValue As Boolean returnValue = instance.EndsWith(value, comparisonType)
[ComVisibleAttribute(false)] public: bool EndsWith ( String^ value, StringComparison comparisonType )
/** @attribute ComVisibleAttribute(false) */ public boolean EndsWith ( String value, StringComparison comparisonType )
ComVisibleAttribute(false) public function EndsWith ( value : String, comparisonType : StringComparison ) : boolean
戻り値
value パラメータがこの文字列の末尾と一致する場合は true。それ以外の場合は false。


EndsWith メソッドは、value パラメータと、この文字列の末尾にある部分文字列とを比較し、両者が等しいかどうかを示す値を返します。等しいという結果を得るためには、value が、この同じインスタンスへの参照であるか、空の文字列 ("") であるか、または、この文字列の末尾と一致している必要があります。EndsWith メソッドによって実行される比較の種類は、comparisonType パラメータの値に依存します。

ある文字列が特定の部分文字列で終わっているかどうかを判断するコード例を次に示します。選択したカルチャ、大文字と小文字の区別、比較の種類 (序数ベースにしたかどうか) が実行結果に影響します。

String.EndsWith メソッド

名前 | 説明 |
---|---|
String.EndsWith (String) | このインスタンスの末尾が、指定した文字列と一致するかどうかを判断します。 .NET Compact Framework によってサポートされています。 |
String.EndsWith (String, StringComparison) | 指定された比較オプションを使って比較した場合に、この文字列の末尾が、指定された文字列と一致するかどうかを判断します。 .NET Compact Framework によってサポートされています。 |
String.EndsWith (String, Boolean, CultureInfo) | 指定されたカルチャを使って比較した場合に、この文字列の末尾が、指定された文字列と一致するかどうかを判断します。 .NET Compact Framework によってサポートされています。 |

String.EndsWith メソッド (String, Boolean, CultureInfo)
アセンブリ: mscorlib (mscorlib.dll 内)

Public Function EndsWith ( _ value As String, _ ignoreCase As Boolean, _ culture As CultureInfo _ ) As Boolean
Dim instance As String Dim value As String Dim ignoreCase As Boolean Dim culture As CultureInfo Dim returnValue As Boolean returnValue = instance.EndsWith(value, ignoreCase, culture)
- culture
このインスタンスと value との比較方法を決定するカルチャ情報。culture が null 参照 (Visual Basic では Nothing) の場合は、現在のカルチャが使用されます。
value パラメータがこの文字列の末尾と一致する場合は true。それ以外の場合は false。


このメソッドは、value パラメータと、この文字列の末尾にある、value とまったく同じ長さの部分文字列とを比較し、両者が等しいかどうかを示す値を返します。等しいという結果を得るためには、value が、この同じインスタンスへの参照であるか、この文字列の末尾と一致している必要があります。
このメソッドは、大文字と小文字の区別とカルチャの種類を引数として受け取り、カルチャに依存する単語ベースの比較を実行します。

次に示すのは、ある文字列が別の文字列の末尾に出現するかどうかを調べるコード例です。EndsWith メソッドは、検索の結果に影響する大文字と小文字の区別の有無、およびさまざまなカルチャを指定して、複数回呼び出されます。
