Merge multidimensional array

Question

I have two arrays (eut1 and eut2) that are rather large and i want to merge them to create a new one containing one after the other. I create the new array but i dont know how to assign eut1 and eut2 to the anglesEut so they end up after each other.

public void setgetAnglesEut(float[,] eut1, float[,] eut2)
{
this.anglesEut = new float[eut1.GetLength(0) + eut2.GetLength(0), eut2.GetLength(1)];

this.anglesEut = eut1;
// when anglesEut is assigned eut1 it also gets its dimentions. How do i add eut2 efter eut1.
// eut1 and eut 2 have the following dimentions
// Eut1 {float[3, 4096]}
// anglesEut {float[6, 4096]}

}

static void Main( string [] args) { float [] arr1 = new float [3 2] { { 0 12 } { 1 25 } { 2 45 } }; float [] arr2 = new float [3 2] { { 0 9 } { 1 17 } { 2 29 } }; int d1 = arr1.GetLength(0) + arr2.GetLength(0); int d2 = arr1.GetLength(1) > arr2.GetLength(1) ? arr1.GetLength(1) : arr2.GetLength(1); float [] result = new float [d1 d2]; AddToArray(result arr1); AddToArray(result arr2 arr1.GetLength(0)); for ( int i = 0; i { for ( int j = 0; j { Console .Write(result[i j] +   ); } Console .WriteLine(); } Console .ReadKey(); } static void AddToArray( float [] result float [] array int start = 0) { for ( int i = 0; i { for ( int j = 0; j { result[i + start j] = array[i j]; } } } It's a bit more complicated than I thought. There are no simple conversions from [] array since this type of array is not multi-dimensional in the same way that the others are for example List > or int[][] where you have list of lists or pointer of pointers.

It can be done in 2 lines if you replace arrays with lists: List > result = new List >(list1); result.AddRange(list2); ;)

Thanks that what i wanted to do but i was hoping there was a way to do it without looping each element. But at least it works.

I cant change anglesEut because it is used by other parts of the program. I can only change the contained data. anglesEut = (float[])eut1.Clone(); Clone() sems like it dose what i want to do but i also want to add the data in eut2 after eut1. eut1 0 12 1 25 2 45 eut2 0 9 1 17 2 29 anglesEut 0 12 1 25 2 45 0 9 1 17 2 29

array1: 123 456 array2: 78 99 12 Do you want this: 12378 45699 12 or this: 12378 45699 00012 this.anglesEut = eut1; - this simply makes anglesEut reference to the the eut1. You have to clone the array: anglesEut = (float[])eut1.Clone(); In any case it'll be simpler to use list with its AddRange method. List can then return an array copy of itself.
