  The <xref:System.Array> class is the base class for language implementations that support arrays. However, only the system and compilers can derive explicitly from the <xref:System.Array> class. Users should employ the array constructs provided by the language.  
 
- An element is a value in an <xref:System.Array>. The length of an <xref:System.Array> is the total number of elements it can contain. The lower bound of an <xref:System.Array> is the index of its first element. An <xref:System.Array> can have any lower bound, but it has a lower bound of zero by default. A different lower bound can be defined when creating an instance of the <xref:System.Array> class using <xref:System.Array.CreateInstance%2A>.A multidimensional <xref:System.Array> can have different bounds for each dimension. An array can have a maximum of 32 dimensions.

  Unlike the classes in the <xref:System.Collections> namespaces, <xref:System.Array> has a fixed capacity. To increase the capacity, you must create a new <xref:System.Array> object with the required capacity, copy the elements from the old <xref:System.Array> object to the new one, and delete the old <xref:System.Array>.
