DataMisalignedException 类

定义

当在某个地址读取或写入一个单元的数据,但该地址的数据大小不是该数据单元的整数倍时引发的异常。The exception that is thrown when a unit of data is read from or written to an address that is not a multiple of the data size. 此类不能被继承。This class cannot be inherited.

注解

某些微处理器 (如64位处理器) 可以在数据被读取或写入未对齐的地址时 (即, 当地址不是所访问数据的大小时大小的倍数) 时发出硬件例外。Some microprocessors, such as 64-bit processors, can issue hardware exceptions when data is read or written to a misaligned address (that is, when an address is not a multiple of the size of the data being accessed). DataMisalignedException当从非两个、四个或八个字节的倍数读取或写入16位、32位或64位数据时, 通常会引发。DataMisalignedException is typically thrown when 16-bit, 32-bit, or 64-bit data is read from or written to an address that is not a multiple of two, four, or eight bytes.

DataMisalignedException公开基础硬件异常, 这允许你以适当的方式进行响应。The DataMisalignedException exposes the underlying hardware exception, which allows you to respond in an appropriate manner. 例如, 应用程序中的例程尝试将字节序列从一个位置复制到64位单元中的另一个位置。For example, a routine in your application attempts to copy a sequence of bytes from one location to another in 64-bit units. 但是, 写入操作以未对齐的地址开始, 这会导致公共语言运行时引发DataMisalignedExceptionHowever, the write operation starts at a misaligned address, which causes the common language runtime to throw a DataMisalignedException. 例程通过一次复制一个字节来响应异常。Your routine responds to the exception by copying the data one byte at a time.
