DisplayMode 枚举

定义

定义用于指示 ByteViewer 所使用的显示模式的标识符。Defines identifiers that indicate the display modes used by ByteViewer.

public enum class DisplayMode
public enum DisplayMode
type DisplayMode = 
Public Enum DisplayMode
继承
DisplayMode

字段

Ansi 2

ANSI 格式的显示。An ANSI format display.

Auto 4

自动选择显示模式的显示模式。A display mode that automatically selects a display mode. 在此模式下,将对字节进行检查,以确定它们是否为十六进制或可打印的格式。In this mode, the bytes are examined to determine if they are hexadecimal or printable. 如果字节为十六进制格式,则将选择 Hexdump 模式。If the bytes are in hexadecimal format, the Hexdump mode is selected. 如果字符匹配可打印的字符集,则运行一项测试,以自动选择 AnsiUnicode 显示模式。If the characters match a printable character set, a test is run to automatically select either the Ansi or Unicode display mode.

Hexdump 1

十六进制格式的显示。A hexadecimal format display.

Unicode 3

Unicode 格式的显示。A Unicode format display.

示例

下面的示例演示如何使用DisplayMode标识符。The following example demonstrates how to use DisplayMode identifiers. 此代码示例是为ByteViewer类提供的更大示例的一部分。This code example is part of a larger example provided for the ByteViewer class.
