I want to get list listview items in the static class. Because I want to pass this class variable to another class. So I have tried... 
  1. public static class FileMngUserID  
  2.        {  
  3.            public static List<int> UserId;  
  4.            public static List<string> ImgName;  
  5.        }  
  6.   
  7. foreach (DocumentsUser item in listView1.SelectedItems)  
  8.            {  
  9.                FileMngUserID.UserId.Add(Convert.ToInt32(item.UserId));  
  10.                FileMngUserID.ImgName.Add(item.Parent_File_Name);                
  11.            }  
 but here  FileMngUserID.UserId.Add(Convert.ToInt32(item.UserId)); occurring error 'Object reference not set to an instance of an object.'
