Silverlight / WPF - Add next line(\n) in a generic List contains more than 100 characters

hi..

i have a generic list contains 100 index values..

for examples

private List<string> _list=new List<string> ();

 _list.Add("The Microsoft Developer Network (MSDN) is the portion of Microsoft responsible for managing the firm's relationship with developers and testers, such as: hardware developers interested in the operating system (OS), and software developers standing on the various OS platforms or using the API and/or scripting languages of Microsoft's applications. The relationship management is situated in assorted media: web sites, newsletters, developer conferences, trade media, blogs and DVD distribution. The life cycle of the relationships ranges from legacy support through evangelizing potential offerings.");

            _list.Add("welcome");

here i need to give "\n" if the index contains more than 100 characters.


i have used the below lines 

 static IEnumerable<string> Split(string str, int chunkSize)
        {
            return Enumerable.Range(0, str.Length / chunkSize)
                .Select(i => str.Substring(i * chunkSize, chunkSize));
        } 


  IEnumerable<string> ss = Split(_list[0].ToString(), 100);  
in the above line i need to pass my whole list values and split if any index contains more than 100 characters.
but i passed the static index value of my list. but i need to pass my whole list.

i dont waant to use for loop. is it possible to achieve this in linq..

need ur suggestions with examples...

Use this working code-


       List<string> _list=new List<string> ();
       _list.Add("a");
       _list.Add("asjgjkfsdhgjkfhsdjkghjkfsdgjkhfksdgkjfjksdgkfsdgkhfsdkggggggggggggggggggggggggggggggggggggggggggggggggggggggggghsdfgjkfsdjkgjkjkjkjkjkjkjkjkjkjkjkjkjkjkjkjk");
       _list.Add("b");


       foreach (string str in _list)
       {
         if (str.Length > 100)
         {
           string s = str.Insert(100, "\n");
         }
       }

Try this and let me know.
