with Clone() the destination array need not exist yet since a new one is created from scratch. with CopyTo() not only does the destination array need to already exist it needs to be large enough to hold all the elements in the source array from the index you specify as the destination. check here for example http://geekswithblogs.net/dforhan/archive/2005/12/01/61852.aspx you can also refer to msdn http://msdn.microsoft.com/en-us/library/system.array.clone.aspx http://msdn.microsoft.com/en-us/library/system.array.copyto.aspx

Hi Amit Normal 0 The first one performs a deep copy of the array the second one is shallow. The CopyTo() method copies the elements into another existing array . The Clone() method returns a new array (a shallow copy) object containing all the elements in the original array. Thanks
