result shows System.String[]

On my GetBusiness.aspx page i have create a test list 

        List<string> l = new List<string>();
        l.Add("one");
        l.Add("two");
        l.Add("three");
        l.Add("four");
        l.Add("five");

        // B.
        string[] s = l.ToArray();

        Response.Write(s);

No on my second page(default aspx page) I have some jQuery to load this array and show the results: 

          $.get('GetBusiness.aspx', function (returndata) {
                            // for each address in returndata
                            alert(returndata);

but the result is : System.String[] If I iterate , he iterate the string "System.String[]"

          $.each(returndata, function (index, value) {
              alert(index + ': ' + value); 
          };

How can I show the results from the string array?

In your GetBusiness page, you are outputting the .ToString() property of the array, which is "System.String[]". You need to iterate the list and output each element separatly in some usable format, like JSON and then parse appropriately.

Example (untested):

string reponse = "";
response += "{ \"Output\":[";
for(int i = 0; i < s.Length; i++) {
  response += s[i];
  if (i < s.Length - 1) response += ", "
}
response += "] }";
Response.Write(response);

List<string> l = new List<string>();
l.Add("one");
l.Add("two");
l.Add("three");
l.Add("four");
l.Add("five");

// B.
string[] s = l.ToArray();

Response.Write(string.Join(",", s));

javascript:

$.get('GetBusiness.aspx', function(returndata) {

    var arr = returndata.split(',');
    $.each(arr, function(index, value) {
        alert(index + ': ' + value);
    });
});

Change Response.Write(s) to :

JavaScriptSerializer objSerializer = new JavaScriptSerializer();
Response.Write(objSerializer.Serialize(s));

Reference: JavaScriptSerializer
