DisplayMode 枚举
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
定义用于指示 ByteViewer 所使用的显示模式的标识符。
public enum class DisplayModepublic enum DisplayModetype DisplayMode = Public Enum DisplayMode- 继承
字段
| Ansi | 2 | ANSI 格式的显示。 |
| Auto | 4 | 自动选择显示模式的显示模式。 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。 如果字节为十六进制格式，则将选择 Hexdump 模式。 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 Ansi 或 Unicode 显示模式。 |
| Hexdump | 1 | 十六进制格式的显示。 |
| Unicode | 3 | Unicode 格式的显示。 |
示例
以下示例演示如何使用 DisplayMode 标识符。 此代码示例是为 ByteViewer 类提供的一个更大示例的一部分。
