Question

我目前有一个Windows窗体，有24个标签，需要定期更新，目前我这样做。

private void UpdateLabels()
    {
        // ------------------------------------------------------------------------
        // Group 1 Team 1
        // -------------------------------------------------------------------------
        lblGroup1Team1Points.Text = Convert.ToString(theTeams[0].returnPoints());
        lblGroup1Team1Points.Refresh();
        lblGroup1Team1Wins.Text = Convert.ToString(theTeams[0].returnWins());
        lblGroup1Team1Wins.Refresh();
        lblGroup1Team1Draws.Text = Convert.ToString(theTeams[0].returnDraws());
        lblGroup1Team1Draws.Refresh();
        lblGroup1Team1Loses.Text = Convert.ToString(theTeams[0].returnLoses());
        lblGroup1Team1Loses.Refresh();
        lblGroup1Team1GoalDifference.Text = Convert.ToString(theTeams[0].returnGoalDifference());
        lblGroup1Team1GoalDifference.Refresh();
        lblGroup1Team1Played.Text = Convert.ToString(theTeams[0].returngamesPlayed());
        lblGroup1Team1Played.Refresh();

        // ------------------------------------------------------------------------
        // Group 1 Team 2
        // -------------------------------------------------------------------------
        lblGroup1Team2Points.Text = Convert.ToString(theTeams[1].returnPoints());
        lblGroup1Team2Points.Refresh();
        lblGroup1Team2Wins.Text = Convert.ToString(theTeams[1].returnWins());
        lblGroup1Team2Wins.Refresh();
        lblGroup1Team2Draws.Text = Convert.ToString(theTeams[1].returnDraws());
        lblGroup1Team2Draws.Refresh();
        lblGroup1Team2Loses.Text = Convert.ToString(theTeams[1].returnLoses());
        lblGroup1Team2Loses.Refresh();
        lblGroup1Team2GoalDifference.Text = Convert.ToString(theTeams[1].returnGoalDifference());
        lblGroup1Team2GoalDifference.Refresh();
        lblGroup1Team2Played.Text = Convert.ToString(theTeams[1].returngamesPlayed());
        lblGroup1Team2Played.Refresh();

        // ------------------------------------------------------------------------
        // Group 1 Team 3
        // -------------------------------------------------------------------------
        lblGroup1Team3Points.Text = Convert.ToString(theTeams[2].returnPoints());
        lblGroup1Team3Points.Refresh();
        lblGroup1Team3Wins.Text = Convert.ToString(theTeams[2].returnWins());
        lblGroup1Team3Wins.Refresh();
        lblGroup1Team3Draws.Text = Convert.ToString(theTeams[2].returnDraws());
        lblGroup1Team3Draws.Refresh();
        lblGroup1Team3Loses.Text = Convert.ToString(theTeams[2].returnLoses());
        lblGroup1Team3Loses.Refresh();
        lblGroup1Team3GoalDifference.Text = Convert.ToString(theTeams[2].returnGoalDifference());
        lblGroup1Team3GoalDifference.Refresh();
        lblGroup1Team3Played.Text = Convert.ToString(theTeams[2].returngamesPlayed());
        lblGroup1Team3Played.Refresh();

        // ------------------------------------------------------------------------
        // Group 1 Team 4
        // -------------------------------------------------------------------------
        lblGroup1Team4Points.Text = Convert.ToString(theTeams[3].returnPoints());
        lblGroup1Team4Points.Refresh();
        lblGroup1Team4Wins.Text = Convert.ToString(theTeams[3].returnWins());
        lblGroup1Team4Wins.Refresh();
        lblGroup1Team4Draws.Text = Convert.ToString(theTeams[3].returnDraws());
        lblGroup1Team4Draws.Refresh();
        lblGroup1Team4Loses.Text = Convert.ToString(theTeams[3].returnLoses());
        lblGroup1Team4Loses.Refresh();
        lblGroup1Team4GoalDifference.Text = Convert.ToString(theTeams[3].returnGoalDifference());
        lblGroup1Team4GoalDifference.Refresh();
        lblGroup1Team4Played.Text = Convert.ToString(theTeams[3].returngamesPlayed());
        lblGroup1Team4Played.Refresh();
    }

这很好用，不会让我弄错，但是当它可以在某种循环中进行更新时它是一个相当漫长的过程 - 所以我基本上要问的是：是无论如何要将现有标签添加到标签数组中，以便我可以通过访问该标签数组中的元素来更新和刷新这些标签？我的想法就像这个一样简单

Label[,] group1Labels = new Label[5,7];
private void CreateLabelArray
    {
        group1Labels[0,0] = lblGroup1Team1Points;
    }

但是我错了，因为group1Labels给了我错误＆＃34;一个get或set accessor预期＆＃34;什么是正确的方法？

Answer 1

不确定这是多么漂亮或快，但你可以尝试类似的东西：

for (int i = 0; i < theTeams.Length; i++)
{
    foreach(Control ctr in this.Controls)
    {
        if (ctr.Name == "lblGroup1Team" + (i + 1) + "Points")
        {
            ((Label)ctr).Text = theTeams[i].returnPoints();
            ((Label)ctr).Refresh();
        }
        //other ifs for each label
    }
}

Answer 2

试试这个列表

foreach (Control c in group1.Controls)
        {
            if (c is Label)
            {
                string name = c.Name;
                // add your code to add in list or array
            }
        }

Answer 3

您可以使用此功能获取所有标签。您可以在表单构造函数中调用它

var labels = GetType()
    .GetFields(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public)
    .Where(x => x.FieldType == typeof(Label))
    .Select(x => (Label)x.GetValue(this))
    .ToArray();

C＃ - 表单上已有的标签数组？
