Convert string to int array using LINQ

Question

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  and perhaps LINQ could help here  Unfortunately I am not very good in LINQ  Is there 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  lt  ia Length    i                int j          string s   sa i           if  int TryParse s  out j                         ia i    j                      return ia

You can shorten JSprangs solution a bit by using a method group instead   string s1    1 2 3 4 5 6 7 8 9 10 11 12   int   ints   s1 Split      Select int Parse  ToArray

s1 Split      Select s   gt  Convert ToInt32 s   ToArray      Untested and off the top of my head   testing now for correct syntax   Tested and everything looks good

Actually correct one to one implementation is   int n  int   ia   s1 Split      Select s   gt  int TryParse s  out n    n   0  ToArray

Here s code that filters out invalid fields       var ints   from field in s1 Split      Where  x    gt    int dummy  return Int32 TryParse x  out dummy                     select Int32 Parse field
