i am getting string array on runtime like this
string[] array1 = {"5", "4", "2"};
values in array is added on runtime on the basis of checkbox selection from
screen (Note: i have 7 check boxes on screen )
if i check 3 check boxes then 3 values will be add in array1 but i want to add
zero at the end of the array in remaining 4 positions in array like this :
string[] array1 = {"5", "4", "2","0" ,"0","0" , "0"};
during runtime just to fix all 7 position in array ...what should i do ??
I don't get the usage of your requirement. But you can fill up the array with "0" with the following code:
List<string> list = array1.ToList();
for (int i = array1.Length; i < 7; i++)
{
list.Add("0");
}
array1 = list.ToArray();
You can do the following:
const int paddedSize = 7;
var newArray = array1.Concat(Enumerable.Repeat("0", paddedSize - array1.Length)).ToArray();
But maybe you'll understand it better without using Linq; the type you want to use is List<string> which can be dynamically resized, arrays can't. In order to get a list out of an array, you can use the linq extension:
var resized = array1.ToList();
Or
var resized = new List<string>(array1);
And now you simply add 0s until the total count of items is 7:
while (resized.Count < paddedSize)
resized.Add("0");
And back to an array:
var newArray = resized.ToArray();
