我正在使用 COM 连接为设备控制器编写代码。在我的代码中,我有 3 个线程,侦听器、编写器和状态询问线程,对于每个线程,我计划使用 Spectre.Console 输出其状态(工作或暂停)和一个计时器以用于测试目的
LiveDisplay
。
我不知道当每个线程的状态属性发生变化时如何更新控制台。更新控制台需要在每次每个线程的状态发生变化时调用
ctx.Refresh()
,但我没有找到一种方法来调用它而不是从 AnsiConsole.Start()
方法。
我使用一个单独的类来存储状态,我从线程向其传递值,实现
INotifyPropertyChanged
。我仍然不确定在单独的类中实现它是否是一个好方法,所以我计划重新审视它,也许将它与控制器类一起加入。
这是我用于存储状态的类:
internal class ControllerData : INotifyPropertyChanged
{
private string _writeThreadState = "";
private string _readThreadState = "";
private string _stateThreadState = "";
private string _actionMessage = "";
public String WriteThreadState
{
get => _writeThreadState;
set
{
_writeThreadState = value;
OnPropertyChanged(nameof(WriteThreadState));
}
}
public String ReadThreadState
{
get => _readThreadState;
set
{
_readThreadState = value;
OnPropertyChanged(nameof(ReadThreadState));
}
}
public String StateThreadState
{
get => _stateThreadState;
set
{
_stateThreadState = value;
OnPropertyChanged(nameof(StateThreadState));
}
}
public String ActionMessage
{
get => _actionMessage;
set
{
_actionMessage = value;
OnPropertyChanged(nameof(ActionMessage));
}
}
public StringBuilder Output { get; set; } = new StringBuilder();
public event PropertyChangedEventHandler? PropertyChanged;
[NotifyPropertyChangedInvocator]
protected virtual void OnPropertyChanged([CallerMemberName] string? propertyName = null)
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}
记录器类:
internal class Logger
{
private ControllerData data;
public Logger(Controller cont)
{
data = cont.loggingData;
data.PropertyChanged += ControllerDataPropertyChangedHandler;
}
private void ControllerDataPropertyChangedHandler(object sender, PropertyChangedEventArgs e)
{
//refresh console
}
public void Start()
{
Table table = new Table()
.Border(TableBorder.Rounded)
.AddColumn("Thread")
.AddColumn("State");
table.AddRow("Listen Thread", data.ReadThreadState);
table.AddRow("Write Thread", data.WriteThreadState);
table.AddRow("Check state Thread", data.StateThreadState);
AnsiConsole.Live(table)
.Start(ctx =>
{
ctx.Refresh();
});
}
}
主要:
static void Main(string[] args)
{
ComConnector connector = new ComConnector();
try
{
Controller cont = new Controller(connector);
Logger log = new Logger(cont);
log.Start();
cont.StartMessaging(20000);
}
catch (Exception e)
{
Console.WriteLine(e);
throw;
}
}
}
这可能需要您重新考虑您的设计,但我通常这样做:
using Spectre.Console;
using SpectreTest;
Console.OutputEncoding = System.Text.Encoding.Unicode;
var table = new Table().AddColumns("Key", "Value");
await AnsiConsole.Live(table).StartAsync(async ctx =>
{
var sim = new CommunicationEmulator();
var entries = new Dictionary<string, int>();
await sim.SimulateAsync(new Progress<Update>(u =>
{
if (entries.TryGetValue(u.Key, out var rowIndex))
{
table.UpdateCell(rowIndex, 1, u.Value);
}
else
{
var columns = new List<Markup> { Markup.FromInterpolated($"{u.Key}"), Markup.FromInterpolated($"{u.Value}") };
var index = table.Rows.Add(columns);
entries[u.Key] = index;
}
ctx.Refresh();
}));
});
public record Update(string Key, string Value);
不管怎样,这显示了一个表格,该表格将由我在此处称为
CommunicationEmulator
的报告进行实时更新。
您可能也可以使用
要点是在
StartAsync
内部循环并发出更新,并保持从某种键到实际表的行索引的映射。
请注意,这不考虑了用户输入。它会一直运行,直到模拟器不再有输入为止。
