Limt of array

Hello leelha,
The max no of elements that can be stored in an array is int32.MaxValue (2 147 483 647) in theory but by default the maximum size of an array is 2 gigabytes as mentioned on MSDN here: http://msdn.microsoft.com/en-us/library/System.Array%28v=vs.110%29.aspx.

In a 64-bit environment, you can avoid the size restriction by setting the enabled attribute of the gcAllowVeryLargeObjects configuration element to true in the run-time environment. However, the array will still be limited to a total of 4 billion elements, and to a maximum index of 0X7FEFFFFF in any given dimension (0X7FFFFFC7 for byte arrays and arrays of single-byte structures).
