DataMisalignedException Class
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.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
The DataMisalignedException type exposes the following members.
| Name | Description | |
|---|---|---|
   | DataMisalignedException() | Initializes a new instance of the DataMisalignedException class. |
| DataMisalignedException(String) | Initializes a new instance of the DataMisalignedException class using the specified error message. |
| DataMisalignedException(String, Exception) | Initializes a new instance of the DataMisalignedException class using the specified error message and underlying exception. |
| Name | Description | |
|---|---|---|
| Data | Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.) |
| HelpLink | Gets or sets a link to the help file associated with this 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.) |
| Source | Gets or sets the name of the application or the object that causes the error. (Inherited from Exception.) |
| StackTrace | Gets a string representation of the immediate frames on the call stack. (Inherited from Exception.) |
| TargetSite | Gets the method that throws the current exception. (Inherited from Exception.) |
| Name | Description | |
|---|---|---|
| Equals(Object) | Determines whether the specified object is equal to the current object. (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.) |
| GetObjectData | When overridden in a derived class, sets the SerializationInfo with information about the exception. (Inherited from Exception.) |
| GetType | Gets the runtime type of the current instance. (Inherited from Exception.) |
| ToString | Creates and returns a string representation of the current exception. (Inherited from Exception.) |
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.
