How to get the no of memory bytes allocated to the Array of type String?

Hi All,

How to get the no of memory bytes allocated to the Array of type String?

Dim arrDetail(100,10) As String

Thanks and Regards

How to get the no of memory bytes allocated to the Array of type String?


The array data itself takes (IntPtr.Size * 101 * 11) bytes. The array
class probably contains a header taking up some additional bytes.

allocated in memeory?

Dim arrDetail(100,10) As Integer

Enjoy Coding,

On a 32-bit platform where the size of an object reference is the same
as the size of an Integer, they take the same amount of memory. On a
64-bit platform the string array would consume twice as much memory.
