I have a function (tointarray) to convert a string into an array of ints, but I am not very satisfied with it. it does the job but there must be a more elegant way to do this, perhaps Linq could help here. unfortunately I am not very good in Linq. do you guys know a better way? my function:

{
    string s1 = "1;2;3;4;5;6;7;8;9;10;11;12";
    int[] ia = tointarray(s1, ';');
}
int[] tointarray(string value, char sep)
{
    string[] sa = value.Split(sep);
    int[] ia = new int[sa.Length];
    for (int i = 0; i < ia.Length; ++i)
    {
        int j;
        string s = sa[i];
        if (int.TryParse(s, out j))
        {
            ia[i] = j;
        }                 
    }
    return ia;
}
