DisplayMode Enumeración

Definición

Espacio de nombres:

System.ComponentModel.Design

Ensamblado:

System.Windows.Forms.Design.dll

Define identificadores que indican los modos de presentación que utiliza ByteViewer.

C#

public enum DisplayMode

Herencia

Object

ValueType

Enum

DisplayMode

Campos

Nombre	Valor	Description
Ansi	2	Presentación en formato ANSI.
Auto	4	Modo de presentación que selecciona automáticamente un modo de presentación. En este modo, se examinan los bytes para determinar si son hexadecimales o imprimibles. Si los bytes tienen formato hexadecimal, se selecciona el modo Hexdump. Si los caracteres coinciden con un juego de caracteres imprimibles, se ejecuta una prueba para seleccionar automáticamente el modo de presentación Ansi o Unicode.
Hexdump	1	Presentación en formato hexadecimal.
Unicode	3	Presentación en formato Unicode.
