There's method for that :

string[] s = "4,5,6".Split(',');

to int array :

int[] ints = s.Select(x => int.Parse(x)).ToArray();

Cheers

Solution 3

Dim str as string="4,5,6"

C++

Dim arr() As String = str.ToString.Split(",")

Now, using for loop you can add this data in any datatable, dataset or as per your requirement.

For Eg. to add this data in Listbox

VB

For i As Integer = 0 To arr.Length - 1
            ListBox1.Items.Add(arr(i).ToString)
        Next

Solution 5

Have a look at String.Split[^] method. Once you have the substrings you may easily convert them to numbers.

Solution 1

C#

string str = "4,5,6";
string[] strings = str.Split(',');

or if you want it as int[]:

C#

string str = "4,5,6";
string[] strings = str.Split(',');
int[] ints = new int[strings.Length];
for(int i = 0; i < strings.Length; i++)
{
  Int32.TryParse(strings[i], out ints[i]);
}
