DataMisalignedException Class

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

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. This class cannot be inherited.

Remarks

Note

This class supports the .NET Framework for Windows Phone library and is not intended to be used by Windows Phone app code.

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.
