ByteViewer-Klasse

Zeigt Bytearrays im hexadezimalen Format, ANSI-Format und Unicode-Format an.

Namespace: System.ComponentModel.Design
Assembly: System.Design (in system.design.dll)

Syntax

'Declaration
Public Class ByteViewer
    Inherits TableLayoutPanel
'Usage
Dim instance As ByteViewer

public class ByteViewer : TableLayoutPanel

public ref class ByteViewer : public TableLayoutPanel

public class ByteViewer extends TableLayoutPanel

public class ByteViewer extends TableLayoutPanel

Hinweise

ByteViewer stellt eine Schnittstelle zum Anzeigen von Daten im hexadezimalen Format, ANSI-Format und Unicode-Format bereit.

Die DisplayMode-Enumeration gibt die Bezeichner an, mit denen der zu verwendende Anzeigemodus angegeben wird. Abhängig vom Inhalt des Bytearrays legt der Auto-Anzeigemodus einen Standardanzeigemodus fest. ByteViewer verwendet einen einfachen Algorithmus, um die Art der Daten zu ermitteln, die im Puffer gespeichert sind. In der hexadezimalen Hexdump-Ansicht werden die hexadezimalen Werte und die zugehörigen Bytedarstellungen (Zeichen) in einem schreibgeschützten Eingabefeld angezeigt. Die Standardspaltenanzahl beträgt 16. In der Ansi-Ansicht und der Unicode-Ansicht wird das Bytearray in einem schreibgeschützten Eingabefeld angezeigt. In diesen Ansichten werden NUL-Zeichen durch Unicode-Blockzeichen ersetzt.

Beispiel

Im folgenden Codebeispiel wird ein ByteViewer-Steuerelement in einem Form gehostet und eine Schnittstelle zum Konfigurieren und Steuern von ByteViewer bereitgestellt.
