WebGetLength (n) gives you the number of cells in the specified dimension (relative to 0). If you have a 3-dimensional array: int [,,] multiDimensionalArray = new int [21,72,103] ; then multiDimensionalArray.GetLength (n) will, for n = 0, 1 and 2, return 21, 72 … WebApr 11, 2024 · Length is a property which specifies the total number of elements in array. While GetLength () is a pre-define method of Array class. It has an argument which specify the dimension. If we pass 0 to GetLenth () method then it returns the size of first dimension. And if we pass 1 to GetLegnth () method then it returns the size of second dimension.
