还是内存泄露，3月份的问题没有彻底解决！

Question

 dataGridView1  绑定了数据  BindingList<T> 类型的，其他线程会改变这个BindingList<T>；T类型：
   public class TaskData : INotifyPropertyChanged
    {
public event PropertyChangedEventHandler PropertyChanged;
        private int _编号;
        public int 编号
        {
            get { return _编号; }
            set
            {
                if (_编号 != value)
                {
                    _编号 = value;
                    try
                    {
                        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("编号"));
                    }
                    catch (Exception err)
                    {
                 
                    }
                }
            }
        }
下面很多字段类型
......}winform 应用程序 ，过一会就开始内存不断增长，几百M，两天下来占用1G多，但我找了几个月了都找不到原因，和解决办法。

Answer 1

额，我们可不知道你到底干了啥，你要是加了100w条记录呢？你从不清list，gc当然不释放，gc只释放你不用的，你说我100w条记录都用，自然微软也不干帮你释放

Answer 2

正常情况下，默认监听list，只显示最近1小时的。如果需要查询以前的则是另外的查询UI去数据持久层找别说dataGridView1，你就是一个execel你不停的写他也扛不住
