Question

I have an arraylist called ‘pri1’, I want this array list to be available to other methods:

void downloader_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
        {
            if (e.Error == null)
            {
                Stream responseStream = e.Result;
                StreamReader responseReader = new StreamReader(responseStream);
                string response = responseReader.ReadToEnd();

                string[] split1 = Regex.Split(response, "},{");
                List<string> pri1 = new List<string>(split1);
                pri1.RemoveAt(0);
                string last = pri1[pri1.Count() - 1];
                pri1.Remove(last);

                List<string> str = pri1;
            }
        }

so a suggestion to me was to save it to a class variable which i did:

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

unfortunately the elements of ‘pri1’ did not successfully pass on to ‘str’:

 void AddPrimaryMarkerGraphics(object sender, getPrimaryListCompletedEventArgs e)
        {
         foreach (string item in str)
          {

So I was wondering where in these 3 steps did I go wrong?

My guess is that you’ve still declared a new local variable within your downloader_OpenReadCompleted instead of assigning to the existing variable:

pri1.RemoveAt(0);
string last = pri1[pri1.Count() - 1];
pri1.Remove(last);
str = pri1;
