C#从控件列表中引发事件

警告：嵌入式软件删除程序正在尝试构建PC软件

我正在尝试连接一个通过串行接口与PC通信的硬件。PC软件（C#）周期性地发送一个字节数组，我想用一些轨迹条来调整它

我没有在设计视图上添加8个轨迹栏，而是添加了一个来帮助我对齐它，然后创建一个列表，在加载时填充，如下所示：

public partial class FormDmxTemplate : Form
{
    // Controls
    // Create a list of tracbars.
    List<TrackBar> trackBarDmx = new List<TrackBar>();

    public FormDmxTemplate()
    {
        InitializeComponent();            
    }

    private void FormDmxTemplate_Load(object sender, EventArgs e)
    {
        // Add first instance on the list
        trackBarDmx.Add(trackBarDmx1);
        // Generate 7 more, 8 total, of each
        // Copy settings, and place them next to each other
        for (int i = 1; i < 8; i++)
        {
            // Trackbars
            trackBarDmx.Add(new TrackBar());
            trackBarDmx[i].TickStyle   = trackBarDmx[0].TickStyle;
            trackBarDmx[i].Orientation = trackBarDmx[0].Orientation;
            trackBarDmx[i].Minimum     = trackBarDmx[0].Minimum;
            trackBarDmx[i].Maximum     = trackBarDmx[0].Maximum;
            trackBarDmx[i].Size        = new System.Drawing.Size(trackBarDmx[0].Size.Width, trackBarDmx[0].Size.Height);
            trackBarDmx[i].Location    = new System.Drawing.Point(trackBarDmx[i-1].Location.X + 60, trackBarDmx[0].Location.Y);
            this.Controls.Add(trackBarDmx[i]);
        }
    }
}

这意味着我想更新字节数组中的相关字节以匹配轨迹栏值，如果可能的话，使用事件

注意：这是一个表单模板，我通过另一个表单加载并关闭它。

您可以在创建轨迹栏时订阅事件。所有事件都可以具有相同的事件处理程序：

trackBarDmx[i].Scroll += trackBarDmx1_Scroll;

然后在处理程序中，您可以找出哪个是这个轨迹栏，它位于哪个索引处（如果需要的话）

我不知道我是否理解你想要实现的目标。这是否满足您的需要：

for (int i = 0; i < 7; i++)
            {
                TrackBar trackBar = new TrackBar();
                trackBar.Tag = i;
                // Other properties
                trackBar.Scroll += new EventHandler(trackBar_Scroll);
            }

顺便说一句，你真的需要保留

轨迹栏的列表吗？
你可以这样做：

    for (int i = 1; i < 8; i++)
    {
       // Trackbars
       trackBarDmx.Add(new TrackBar());
       trackBarDmx[i].TickStyle   = trackBarDmx[0].TickStyle;
       trackBarDmx[i].Orientation = trackBarDmx[0].Orientation;
       trackBarDmx[i].Minimum     = trackBarDmx[0].Minimum;
       trackBarDmx[i].Maximum     = trackBarDmx[0].Maximum;
       trackBarDmx[i].Size        = new System.Drawing.Size(trackBarDmx[0].Size.Width, trackBarDmx[0].Size.Height);
       trackBarDmx[i].Location    = new System.Drawing.Point(trackBarDmx[i-1].Location.X + 60, trackBarDmx[0].Location.Y);
       this.Controls.Add(trackBarDmx[i]);

       // Notice no number in the handler name
       trackBarDmx[i].Scroll += trackBarDmx_Scroll;
     }

for (int i = 0; i < 7; i++)
            {
                TrackBar trackBar = new TrackBar();
                trackBar.Tag = i;
                // Other properties
                trackBar.Scroll += new EventHandler(trackBar_Scroll);
            }

void trackBar_Scroll(object sender, EventArgs e)
        {
           // Get the trackbar
            TrackBar current = sender as TrackBar;
            // Do something here. Use tag property to identify which byte array should be changed
        }

    for (int i = 1; i < 8; i++)
    {
       // Trackbars
       trackBarDmx.Add(new TrackBar());
       trackBarDmx[i].TickStyle   = trackBarDmx[0].TickStyle;
       trackBarDmx[i].Orientation = trackBarDmx[0].Orientation;
       trackBarDmx[i].Minimum     = trackBarDmx[0].Minimum;
       trackBarDmx[i].Maximum     = trackBarDmx[0].Maximum;
       trackBarDmx[i].Size        = new System.Drawing.Size(trackBarDmx[0].Size.Width, trackBarDmx[0].Size.Height);
       trackBarDmx[i].Location    = new System.Drawing.Point(trackBarDmx[i-1].Location.X + 60, trackBarDmx[0].Location.Y);
       this.Controls.Add(trackBarDmx[i]);

       // Notice no number in the handler name
       trackBarDmx[i].Scroll += trackBarDmx_Scroll;
     }

private void trackBarDmx_Scroll(object sender, EventArgs e)
{

   var tb = sender as TrackBar;

   if(sender == null)
   {return;}

   switch (sender.Name)
   {

       case "trackBarDmx1_Scroll" :
       // handle changes to bar 1
       break;

       // and so on

   }

}
