arrays - Error only apears while running program as a stand alone C# -

the error occurs when resizing array on 1 specific array , when programme run outside of vs idea. when nail compile , run, no errors of description occurs.

here code intended resize array :

resizearray(zbuffer, new int[] {xdisplay});

and here method fetched net resize array :

private static array resizearray(array arr, int[] newsizes) { if (newsizes.length != arr.rank) throw new argumentexception("arr must have same number of dimensions " + "as there elements in newsizes", "newsizes"); var temp = array.createinstance(arr.gettype().getelementtype(), newsizes); int length = arr.length <= temp.length ? arr.length : temp.length; array.constrainedcopy(arr, 0, temp, 0, length); homecoming temp; }

this never happened me , didn't think possible.

try add together next lines:

private static array resizearray(array arr, int[] newsizes) { // add together next 4 lines if (newsizes == null) throw new argumentnullexception("newsizes null!"); if (arr == null) throw new argumentnullexception("arr null!"); if (newsizes.length != arr.rank) throw new argumentexception("arr must have same number of dimensions " + "as there elements in newsizes", "newsizes"); var temp = array.createinstance(arr.gettype().getelementtype(), newsizes); int length = arr.length <= temp.length ? arr.length : temp.length; array.constrainedcopy(arr, 0, temp, 0, length); homecoming temp; }
