DataMisalignedException Class

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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.

[ComVisibleAttribute(true)]
public sealed class DataMisalignedException : SystemException

The DataMisalignedException type exposes the following members.

Properties

	Name	Description
	Data	Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.)
	HResult	Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.)
	InnerException	Gets the Exception instance that caused the current exception. (Inherited from Exception.)
	Message	Gets a message that describes the current exception. (Inherited from Exception.)
	StackTrace	Gets a string representation of the frames on the call stack at the time the current exception was thrown. (Inherited from Exception.)

Methods

	Name	Description
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetBaseException	When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the runtime type of the current instance. (Inherited from Exception.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Creates and returns a string representation of the current exception. (Inherited from Exception.)

Remarks

Note:
This class supports the .NET Framework for Silverlight library and is not intended to be used by Silverlight application 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.
