集合的大小是固定的

Question

list.RemoveAt(index)的时候老是报错，说集合的大小是固定的，用remove也是，请问这是怎么回事。

Answer 1

需要把前后代码贴出来，都不知道list是什么类型的

Answer 2

IList<AndroidTools2WebService.ListStorage> webListStorage = new List<AndroidTools2WebService.ListStorage>();  //这是定义  for (int i = 0; i < webListStorage.Count; i++)
                            {
                                if (webListStorage[i] == null)
                                    continue;
                                string tempId = webListStorage[i].ResourceId.ToString();
                                if (tempId.Equals(id))
                                {
                                    //移除控件中的选中项
                                    lvImageSequence.Items.RemoveByKey(id);
                                                                     
                                    
                                    int a = webListStorage.IndexOf(webListStorage[i]);                                    //webListStorage = tempList;                                 
                                    webListStorage.RemoveAt(a);
                                   
                                    break;
                                }
                            }
                        }
                    }
                }
这是后台代码

应该是不要在遍历的时候删除，，， 你可以记下key的集合 然后慢慢删吧、
