Not sure why this was downvoted - shows two different methods in a simple way. 5'd for balance

Maciej Los 7-May-14 9:10am

Thank you, CHill60 ;)<br>
I suspect the reason: samples doesn't provide direct code(way) to achieve what OP wants to achieve.

Sanket Saxena 7-May-14 9:16am

Actually i am not sure with your solution because it is not satisfying the OP's requirement thats why didnt comment on your solution even not downvoted.

Maciej Los 7-May-14 9:25am

Thank you for clarification.

thanks and always welcome :)

Solution 6

It is possible with one line of LINQ Code :)

C#

string[] array1 = new string[] { "1", "2", "3"};
string[] array2 = new string[] { "6", "7", "8"};

string[] MergedArray = array1.Zip(array2, (a,b)=> new[]{a,b}).SelectMany(x=>x).ToArray();

I think there is a Bug in this voting widget, two have +5, but it is showing as one +5, one +3 and one 1+ :)

Solution 3

C#

int [] SouceArray1 = new int[] {2,1,3};
int [] SourceArray2 = new int[] {4,5,6};
int [] targetArray = new int [SouceArray1.Length + SourceArray2.Length];
SouceArray1.CopyTo(targetArray,0);
SourceArray2.CopyTo(targetArray,SouceArray1.Length) ;
foreach (int i in targetArray) Console.WriteLine(i + " ");

it will just merge the array but not serves the purpose of the OP. its requirement is different.

Manivignesh 7-May-14 7:49am

Thanks for the code...but this code helps to add two arrays one by one..but i need to add the first index element of first array with the second index element of the second array...

Solution 7

Try this

C#

int[] array1 = { 1, 2, 3, 4, 5 };
           int[] array2 = { 6, 7, 8, 9, 10 };
           var list = new List<int>();
           for (int i = 0; i < array1.Length; i++)
           {
               list.Add(array1[i]);
               list.Add(array2[i]);
           }
           int[] array3 = list.ToArray();

Solution 5

No direct method to do so....as you need to merge the first element of the first array with the first element of the second array then second element of the first array to the second element of the second array.

You should use loop for this.

Hope it helps :)

No need to loop if you know LINQ

Sanket Saxena 7-May-14 7:54am

yes. we can avoid loop if use LINQ.

Maciej Los 7-May-14 8:50am

Well... Not true! Using loop = ineffective way!

Maciej Los 7-May-14 9:26am

Thank you for clarification (in the comment to my answer). In this case, you're right. +5!

Sanket Saxena 7-May-14 9:33am

Great thanks Maciej :)
