c#中如何将一个数组拆分多个小数组

如图所示，每3个存为一个数组，该怎么写呢？请各位大神赐教！谢谢！

 int[] data = {1,2,3,4,5,6,7,8,9};
int[][] result = Enumerable.Range(0, data.Count() / 3).Select(x => data.Skip(x*3).Take(3).ToArray()).ToArray();

 int[] x = {1,2,3,4,5,6,7,8,9};
int[][] result = Enumerable.Range(0, x.Count() / 3).Select(x => x.Skip(x*3).Take(3).ToArray()).ToArray();
