在 flowlayout 面板内双击打开标签上的表单

Question

我正在尝试 Double Click 在 FlowLayoutPanel 中的 Label 上，标签是动态创建的。我正在尝试使用此

打开表单

foreach(Label label in myFlp )
{
    var Id = label.Name.ToString();
    int personID;
    if (!String.IsNullOrWhiteSpace(Id) && int.TryParse(Id, out personID))
    {
        FrmAddress frmAddress = new FrmAddress(_controller, personID);
        frmAddress.ShowDialog();
        frmAddress.Dispose();
    }
}

收到此错误；

foreach statement cannot operate on variables of type 'System.Windows.Forms.FlowLayoutPanel' because 'System.Windows.Forms.FlowLayoutPanel' does not contain a public definition for 'GetEnumerator'

尝试这样的事情：

foreach(var control in myFLp.Controls)
{
    if(control is Label)
    var Id = (Label)control.Name.ToString();
    int personID;

    if (!String.IsNullOrWhiteSpace(Id) && int.TryParse(Id, out personID))
    {
        FrmAddress frmAddress = new FrmAddress(_controller, personID);
        frmAddress.ShowDialog();
        frmAddress.Dispose();
    }
}
