c# - How to select the comma in multidimensional array? -

i have been developing application quite long time now, started using rectangular array:

int[,] array = new int[900,800] 

but after giving higher values turned out caused lot of outofmemoryexception problems, decided replace multidimensional array this:

int[][] array /*init stuff*/ 

but after doing compiler gave me 3000 errors (obviously), require lot of time fix manually, started thinking regular expressions replace ',' ']['. want select , inside array square brackets. far got:

(?<=array\[).*, 

which selects ',' right, selects rest of index like:

array[aaa,bbb]       ^^^^ array[bbbb,ccc]       ^^^^^ 

is there way select ',' like:

array[aaa,bbb]          ^ 

note: doesn't have 100% perfect, want work in of cases. thanks.

you can use expression:

\[([0-9]+),\s*([0-9]+)\] 

and replace with:

[$1][$2] 

this expression matches less current attempt, result in less error-prone matching.
