Limitation of memory

Question

Dear all,
I am working on a virtual machine with 58GB ram, in Microsoft Azure. In my program, I have an Byte array which the dimensions are : [10126,24738,24]. When I want to run the program, the memory exception occurs , but when I calculate the ram is enough for
this array size. Is there any limitation from the visual studio for the array size? If yes can I solve it?
Thanks in Advance

Indeed.  But it doesn't help in this particular case, as arrays are still indexed by signed 32bit integers.
eg
if you turn on support for very large objects
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<runtime>
<gcAllowVeryLargeObjects enabled="true"/>
</runtime>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
</configuration>
You can have an array whose total size is larger than 2GB, but you can't have an array with more than UInt32.MaxValue items in it.  eg
var EightGBArrayOfULong = new UInt64[1024 * 1024 * 1024]; //works
var EightGBArrayOfBytes = new byte[1024 * 1024 * 1024, 8]; //fails
