Public Enumeration LayoutKind

[ComVisibleAttribute(true)]
public enum LayoutKind

	Member name	Description
	Sequential	The members of the object are laid out sequentially, in the order in which they appear when exported to unmanaged memory. The members are laid out according to the packing specified in StructLayoutAttribute.Pack, and can be noncontiguous.
	Explicit	The precise position of each member of an object in unmanaged memory is explicitly controlled. Each member must use the FieldOffsetAttribute to indicate the position of that field within the type.
	Auto	The runtime automatically chooses an appropriate layout for the members of an object in unmanaged memory. Objects defined with this enumeration member cannot be exposed outside of managed code. Attempting to do so generates an exception.
