how to create 2d arrays of large size ?

Question

hello, i wish to know can i create 2D arrays of double datatype with large size like 120,000 X120,000? I came to know that in .net the upper bound on index in any single dimension is 2,147,483,591 (0x7FFFFFC7) for byte arrays. because of this i get an error saying memory not sufficient. any help. your inputs will be of great value to me. 


thank you
