winfrom 表格数据自动刷新实现

应用场景

        在winfrom 下通过表格实现数据的实时刷新，确保性能稳定界面流畅，本案例是通过AntdUI控件下的table控件实现的，实现逻辑不受限空间控件：

实现逻辑

1、想要数据自动刷新更新界面，需要使用实体类实现NotifyPropertyChangedBase进行通知控件更新

//自定义的通知类，以下可以简写
public class NotifyPropertyChangedBase : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler? PropertyChanged;
    private SynchronizationContext? _syncContext;
    public void SetSynchronizationContext(SynchronizationContext context)
    {
        _syncContext = context;
    }

    protected void OnPropertyChanged([CallerMemberName] string? propertyName = null)
    {
        try
        {
            if (_syncContext != null && _syncContext != SynchronizationContext.Current)
            {
                _syncContext.Post(_ =>
                    PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName)),
                    null);
            }
            else
            {
                PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
            }
        }
        catch (Exception ex)
        {
        }
    }

    protected bool SetProperty<T>(ref T storage, T value, [CallerMemberName] string propertyName = null)
    {
        try
        {
            if (EqualityComparer<T>.Default.Equals(storage, value))
            {
                return false;
            }

            storage = value;
            OnPropertyChanged(propertyName);
            return true;
        }
        catch (Exception ex)
        {
            return false;
        }
    }

    protected string fromateTime(string hr, string min, string sec)
    {
        return $"{hr}：{min}：{sec}";
    }
}

//更新Model类 
public class DemoModel : NotifyPropertyChangedBase
 {
     private string _name = string.Empty;
     /// <summary>  
     /// 姓名  
     /// </summary>  
     public string Name
     {
         get => _name ;
         set
         {
             if (_name == value) return;
             _name = value;
             OnPropertyChanged();
         }
     }

     private int _age = 0;
     /// <summary>  
     /// 年龄  
     /// </summary>  
     public string Age
     {
         get => _age;
         set
         {
             if (_age== value) return;
             _age= value;
             OnPropertyChanged();
         }
     }
}

2、数据绑定控件更新

必须通过BingdList<T>承载数据集合，table控件通过table.Binding(dataList)进行绑定；

3、定时刷新列表数据

//定时刷新方法
public static void RefreshData()
{
    // 临时禁用列表变更通知
    if (dataList is BindingList<DemoModel> bindingList)
    {
        //暂停界面刷新
        var oldRaise = bindingList.RaiseListChangedEvents;
        bindingList.RaiseListChangedEvents = false;
        try
        {
            Stopwatch stopwatch = Stopwatch.StartNew();
            Parallel.ForEach(dataList, item =>
            {
                item.Age= new Random().Next(150);
                item.Name= new Random().Next(1000).ToString();
            });

            stopwatch.Stop();
            Logger.Info($"数据刷新完成，耗时：{stopwatch.ElapsedMilliseconds}毫秒");
           
        }
        catch (Exception)
        {
            bindingList.RaiseListChangedEvents = oldRaise;
            bindingList.ResetBindings(); // 触发一次全局刷新
        }
    }
}

测试列表一次绑定5000条数据，每2秒对5000条数据进行刷新界面流畅无卡顿；
