  Whats wrong with this for loop?

  Mar 19, 2012 04:11 PM|LINK

  whats the problem with the following code, its giving me tough time for almost half a day.

  if ((extImage != null))
                      {
                          string[] ast_url = null;
                          ast_url[0] = "";
                          ast_url[1] = "";
                          ast_url[2] = "";
                          ast_url[3] = "";
                          ast_url[4] = "";
  
                          for (int i = 0; i < 5; i++)
                          {
                              if (extImage[i] != null)
                              {
                                  asset link = extImage[i];
                                  ast_url[i] = link.url;
                              }
                          }

  Is it not compiling or is it not producing the correct result? It it hanging?

  its giving the following error

  Object reference not set to an instance of an object.

  When I remove the empty string assignments, then it gives another error of object refernce not set to an instance of an object

  Change:

  string[] ast_url = null;
  
  to

  string[] ast_url = new string[5];
