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 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.

The DataMisalignedException exposes the underlying hardware exception, which allows you to respond in an appropriate manner. For example, a routine in your application attempts to copy a sequence of bytes from one location to another in 64-bit units. However, the write operation starts at a misaligned address, which causes the common language runtime to throw a DataMisalignedException. Your routine responds to the exception by copying the data one byte at a time.
