StringCollection.AddRange メソッド

文字列配列の要素を StringCollection の末尾にコピーします。

Public Sub AddRange( _
   ByVal value() As String _)
[C#]
public void AddRange(string[] value);
[C++]
public: void AddRange(String* value __gc[]);
[JScript]
public function AddRange(
   value : String[]);

パラメータ

• value
  StringCollection の末尾に追加する文字列配列。配列自体を null 参照 (Visual Basic では Nothing) にすることはできませんが、配列に格納する要素は null 参照 (Nothing) であってもかまいません。

例外

解説

StringCollection は、 null 参照 (Visual Basic では Nothing) を有効な値として受け取り、要素の重複を許可します。

使用例

[Visual Basic, C#, C++] StringCollection に新しい要素を追加するコード例を次に示します。
