Hi, i put some data in xml, i get the data out of the xml and put it in a
string
string data= "1;2;3;4"

So i need something that do the ; away and puts every number into the array
i:

1 goes to i[0]
2 goes to i[1]

and so on........

How can i do this?

Do you mean sth. like:
string _content = "1;2;3"

int _nPos = _content.IndexOf(";");

int i = 0;

while ( _nPos > 0 )

{

myArray[i++] = int.Parse(_content.Substring(0, _nPos ));

_content = _content.Substring(_nPos+1);

_nPos = _content.IndexOf(";");

}

Yes, thx, but there is a little problem, the last number (3), isn't in the
array, so how can i fix it that it is add to the array?

Thx

JC,

i'm not sure if it is possible to change the size of an array at runtime (i
believe you can't).
use arraylist and addrange() instead of array.

Jergen,

You could also use String.Parse to separate the parts of the string. You
could estimate the size of array you'd need from the length of the string.

Have a look at regular expressions.
The following is taken from the msdn on the Regex.Split method

Regex r = new Regex("(-)"); // Split on hyphens.
string[] s = r.Split("one-two-banana");

following the example, your code would become

Regex r = new Regex("(;)"); // Split on hyphens.
string[] s = r.Split("1;2;3;4");

In his case you don't even need the regular expressions
string[] items = "1;2;3;4".Split(';');
int[] values = new int[items.Length];
for( int i = 0; i < items.Length; i++ )
values = int.Parse(items);
