BitConverter 类
将基础数据类型与字节数组相互转换。
**命名空间:**System
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
Public NotInheritable Class BitConverter
用法
可对静态类的成员直接进行访问，无需类的实例。
public static class BitConverter
public ref class BitConverter abstract sealed
public final class BitConverter
public final class BitConverter
备注
此类便于操作基本形式的类型。一个字节定义为一个 8 位无符号整数。
示例
下面的代码示例演示多个 BitConverter 类方法的用法。
