Im trying to excersize on substring but its not working good

the code is:

private void test()          {              int countfiles = 0;              byte[] a;              string starttag = "t256=\"";              string endtag = "\"";              int starttagwidth = starttag.length;              int endtagwidth = endtag.length;              index = 0;              w = new streamwriter(@"c:\test.txt");              while (true)              {                  index = f.indexof(starttag, index);                  string test = f.substring(index , starttagwidth);                  if (index == -1)                  {                      break;                  }

the starttag t256= endtag should 1 qouta "

i need find between t256 , "

for example if have t256="hi mose" need hi mose

for im getting t256=

what should next ? ( substring testing far not need in final result )

hi danieli,

i found old code in library.  it working fair requirement.

private void form1_load(object sender, eventargs e)         {             string data = "t256=\"hi mose\"";             string starttag = "t256=\"";             string endtag = "\"";              string result = getstringbetween(data, starttag, endtag);         }          public string getstringbetween(string data, string startkey, string endkey)         {             if (string.isnullorempty(data) || string.isnullorempty(startkey) || string.isnullorempty(endkey))                 return string.empty;              if (!data.contains(startkey) || !data.contains(endkey))                 return string.empty;              int ix_start = data.indexof(startkey);             int ix_end = data.indexof(endkey, ix_start + startkey.length);              int valuestart = ix_start + startkey.length;              string ret = data.substring(valuestart, ix_end - ix_start - startkey.length);              return ret;         }

please try it.
