c# - Windows Phone - Listbox items on array -

i have listbox on windows phone app, listbox receive values collection. put listbox items on array. so, need value first list item, received value app1.pivotpage1+fields.

the collection item want show fnome. how it?

my code:

private void button_click(object sender, routedeventargs e)     {          string[] array = new string[list2.items.count];          (int = 0; < list2.items.count; i++)         {             object s = list2.items[i];             array[i] = s.tostring();         }          tjsonobject jobject = new tjsonobject();         tjsonpair jpair = new tjsonpair("test", array[0]);         tjsonpair jpair1 = new tjsonpair("test1", "test1");         tjsonarray jarray = new tjsonarray();          jobject.addpairs(jpair);         jobject.addpairs(jpair1);         jarray.add(jobject);           messagebox.show(jarray.tostring());      } 

my collection:

public observablecollection<fields> items { get; set; }      public class fields     {          [jsonproperty(propertyname = "fid")]         public int fid { get; set; }          public string fnome { get; set; }         public float festado1 { get; set; }         public string fpais { get; set; }         public string quantity { get; set; }         public string lero { get; set; }         public string quantity1 { get; set; }         public string festado { get; set; }       } 

my code working fine now. changed code:

private void button_click(object sender, routedeventargs e) {      string[] array = new string[list2.items.count];      (int = 0; < list2.items.count; i++)     {         object s = list2.items[i];         array[i] = s.tostring();     }      tjsonobject jobject = new tjsonobject();     tjsonpair jpair = new tjsonpair("test", array[0]);     tjsonpair jpair1 = new tjsonpair("test1", "test1");     tjsonarray jarray = new tjsonarray();      jobject.addpairs(jpair);     jobject.addpairs(jpair1);     jarray.add(jobject);       messagebox.show(jarray.tostring());  } 

for this:

 private void button_click(object sender, routedeventargs e)     {          fields[] array = list2.items.cast<fields>().toarray();          tjsonobject jobject = new tjsonobject();         tjsonpair jpair = new tjsonpair("fnome", array[0].fnome);         tjsonpair jpair1 = new tjsonpair("test1", "test1");         tjsonarray jarray = new tjsonarray();          jobject.addpairs(jpair);         jobject.addpairs(jpair1);         jarray.add(jobject);          messagebox.show(jarray.tostring()); }
