Public NotInheritable Class BitConverter
静的クラスのメンバは、クラスのインスタンスなしに直接アクセスされます。
public static class BitConverter
public ref class BitConverter abstract sealed
public final class BitConverter
public final class BitConverter
このクラスを使用すると、値の型を基本的な形式で操作できます。1 バイトは、8 ビットの符号なし整数として定義されます。
BitConverter クラスの一部のメソッドの使用方法を次のコード例に示します。
