String.Format: Input string was not in a correct format [closed]

Answer 1

In addition to escaping your curly braces also try changing your String[] definition to:

int id = 112;

String[] newData = {id.ToString(), "1", "2", "21", "reidb", "reidb", "reidb", "reidb", "aa", 
          "Some description", "11", "2012-02-28", "2012-01-29", "true", "1", "1", 
          "true", "note note note", "true", "1", "2011-12-03", "45"};

and change your String.Format to:

String cmd = String.Format(data,newData);
